Why did my snake bite me?


If you’ve kept snakes for any amount of time you’ve very likely been bit at some point by one of them. Many times there is a simple explanation as to why a snake is biting the hand that feeds it:

  • Handling a rodent and not washing your hands
  • The snake feels threatened
  • Your snake misses a feeding strike and gets your hand
  • You’re Chewy from SnakeBytes TV and seem to like it

At other times a snake that has been docile and easily handled for years will suddenly and inexplicably start striking at anyone and everyone who comes near it. Often this is accompanied with violent displays of hissing, thrashing about the tank, and showing of the inside of the mouth. Personally I’ve dealt with three snake’s that began for no good reason to behave like this. All 3 were ball pythons, considered by many people to be the most docile snake there is. Which just goes to show that no species of snake is immune.


Snake Bites Hand

What makes a snake suddenly become aggressive?
I’ve never found a solid answer to this question but there seems to be a few factors which come into play:

The snake is more stressed than it was before:
It could be due to a simple environmental change. For example maybe you moved the tank into another room and the snake has to deal with more noise and foot traffic. Ask yourself what could be stressing the snake out. One of the ball pythons I mentioned became stressed and began striking when I put in a new washer and dryer. I finally figured out that the vibrations were driving the snake up the wall. After putting down some foam padding to muffle the noise the snake went back to it’s old, calm self. Here are a few examples of things that might stress out your pet snake and make it more prone to biting:

  1. Appliances
  2. More foot traffic
  3. A new pet in the house (other animals often love to harass pet snakes)
  4. Improperly maintained temperatures and humidity levels

The snake doesn’t like you:
Ok, so that’s not really possible as a snake isn’t capable of like or dislike. However there might be something you are doing that agitates it. A corn snake I had at one point would constantly strike at my ex girlfriend any time she tried to get it out. Everyone else could hold the snake all day long and nothing would happen. Finally we figured out that a bracelet she wore would set the snake off. Once we realized that she just took the bracelet off before trying to handle the snake and everything was fine. Strange thing was that anyone else wearing the bracelet had no problems, only her.

Another snake, the second of the three ball pythons I mentioned, would strike at anyone wearing clothes washed in Arm & Hammer laundry detergent. Once I figured that out I switched detergents and the snake stopped being aggressive. From what I could tell it was only triggered by the Arm & Hammer detergent and then only the liquid version. That’s not to say I tested all possible detergents, but I was able to narrow it down and eliminate the problem. If you have a snake that is biting try to pay attention to the little things and see if there’s not something simple that might be causing it to react in a defensive manner.

The snake is ill or injured
Just like a person, or any other living creature when a snake isn’t feeling well it can get grumpy. Before you assume that the snake is just being a “jerk” check to make sure it isn’t hurting. Even though they can’t vocalize a snake still has nerves and still feels pain. A friend of mine had a Rat Snake that suddenly became an absolute terror. Turned out to be a piece of substrate had been lodged into the roof of its mouth. Once the vet got it out and the snake had 2 weeks of being left alone it went back to normal. If your snake starts to strike at everyone around it check to make sure that there isn’t an injury or illness. If need be don’t hesitate to get a vet involved.

What if the snake won’t go back to being “nice”?
It ultimately comes down to the snake, and yourself. It can be a tough decision but remember your own health and safety has to take priority. A small snake, such as a ball python can draw blood, and cause some pain but for the average adult they pose very little health risk. On the other hand a Boa Constrictor could easily kill a full grown adult male if things get too far out of hand. You’ll need to evaluate a few things in deciding what to do with a snake that has become aggressive and won’t stop:

  1. Can you handle it on your own?
  2. Are you putting yourself or anyone else at risk?
  3. Is someone more experienced more appropriate to own the snake? I don’t generally recommend passing your problems on to others but sometimes someone with more knowledge will be able to handle a biting snake better
  4. If the snake were to strike someone aside from you what kind of liability is involved. A snake that is a classroom pet could become a problem if parents start hearing it is biting their kids

There are other questions you can ask but that should give you an example.

Have you had to deal with any pet snakes which have suddenly and for no obvious reason begun biting and striking at people? How did you end up having to handle the situation?

    Could my son’s Red Tailed Boa be getting aggresive because of not handleing it enough. Meaning it gets aggressive when it sees someone or the tank is opened. Is the snake taking that as feeding time?? Also, Someone told me they can get parasites and that can make them aggresive?? Any help would be great thanks…..

  • PetSnakes

    Dan, that is absolutely possible. Reptiles aren’t like dogs. What I mean is you can’t leave on a trip for 3 weeks and they remember you. If you aren’t handling a snake enough it will start to forget who you are.

    It is also possible that the snake is associating the opening of it’s cage with feeding time. Especially if that’s the only reason the cage gets opened. It needs to see that there’s a difference between the tank being opened/approached for feeding and opened/approached for cleaning, handling, etc.

    As far as parasites go I’ve heard the same but never experienced it. Though it makes sense. Any living animal that doesn’t feel well tends to get grumpy. I don’t see why a snake would be any different. To rule out the possibility of parasites get it to a vet that specializes in exotic animals, particularly snakes and have them run some tests. If you look in out pet snakes by state section and choose your state you’ll see a link to vets in your state that handle exotics. If your snake isn’t listed yet just reply here with what state you are in and I’ll get the information for you.

    We were given a corn snake from a coworker whose son was no longer interested in it. He said it never bite him. It has bitten my son twice. They said they feed him 7 to 10 days and that he is 2 years old. He is very small for his age according to a corn snake book I read and not very active. The first time I feed him he seemed interested in another pinkie and I talked to a pet shop owner who said to feed 4 to 5 days. So I started to feed every 4th day and feed bigger pinkies. I made sure my son played with him on the 2nd and 3rd days. He now is very active but my son is getting scared of him. Am I feeding to much? Or what could be wrong? I make sure my son washes his hands before touching the snake.

  • kim

    i have a corn snake i have had him for like 6 weeks. iv handled him alot and he has always been calm and nice, but i havent handeled him for a week and he was out roaming his tank so i picked him up as soon as i grabbed him he freaked out and bit me, so i dropped him back in his tank and he keeps like rattleing his tail agenst the tank.also i was feeding him and he tryed to bite me again and would become aggresive if anyone even looked at him. can you please help??
    thanx

  • PetSnakes

    Laura – There’s often a “feeling out” period that a snake and new owner will go through during which time you can expect to get bit. Sometimes, for reasons entirely unknown to me, a snake will be fine with 100 other people but for a while they will bite that one “special” person. It sounds like your son is that person. In almost all cases, except for very aggressive snakes, regular handling will help the snake to calm down. Your son should be handling the snake for a few minutes every day except for 2 days following a feeding and while the snake is in shed. He should also expect to get bit while the snake gets used to him. Assuming he’s not hurting the snake by being to rough things should calm down sooner than later. Maybe have him wear some soft cloth gardening gloves and a long sleeve shirt if he’s afraid of getting bit by the snake.

  • PetSnakes

    Kim – A snake is never tamed. It’s not like a dog. They become acclimated to being handled. Sounds like your snake forgot about being handled. If that’s the case regular handling should help it get used to you again. On the other hand if the snake is injured, or your husbandry is off you’ll need to correct those issues first.

  • Justin

    I am also having an issue with biting. I bought a young kingsnake about 6 months ago. I handling her daily but every time I pick her up she bites me but it is not a strike. She bites and holds on and wraps herself around my hand as if she is going to eat me (she is only 24 inches long and a little thicker than a nickel). I feed her once a week with an appropriately sized mouse. I also feed her in a separate container. I have caught wild snakes that are more friendly than my kingsnake. Does anybody have any suggestions?

  • Jay

    Same here. My kingsnake is about 24 inches and got grumpy after we moved out of state. My girlfriend’s mom was taking care of her for two months before she gave her back to us. I think she wasn’t monitoring the humidity level in the tank very well and she started feeding her with small mice instead of pinkies. So now she bites my hand every time before I grab her but then settle down and just calmly moves around. I haven’t played with her much because of her new behavior. She hasn’t eaten in two weeks and a half week either, making me waste about 4 mice. She looks healthy though, enough the scare the fuzz out of me when she strikes. Her attacking stance is quite scary too… So I guess patience and bites should do the trick. What king of foaming did you use to isolate the tank? Maybe that would also help…

  • Antony

    I have a 2 corn only a year old my female has just started to bit today for the 1st time. I handle them everyday worried they might have mated are they to young could that be y she’s bitting

  • Tracey

    Hi Antony, first off, I’m not a herp expert, I have 2 corn snakes and a boa constrictor myself and read up alot on them. I notice you think the snakes may have mated. I have just recently learned that corn snakes should be three years old, three feet long and at least three hundred grams for them to mate healthy. Your snakes are way too young and small to be mating, perhaps she has not liked the attention the male may be paying to her so doesn’t like any attention. You may be putting pressure on a tender spot if she was biten herself or got hurt. Perhaps you have a scent on your hands that smells like food to her. I suggest a vet as snakes can’t “tell” you what’s wrong. Good luck

  • Dani Malloy

    hi i just got a quick question! I Got my first corn snake ruby last week and she had a rough time setteling in. I didnt handel her for the first 3 days.. to give her a setteling in period.. and then she fed.. tonight shes hungry again and she just fed.. i dont wanna handel her now incase she regurges.. she is very tame but im just wondering will not handeling her for the week do any damage to this?

  • Sarah

    Hi,
    My snake (1 year Ball Python) has always been really nice. Then the other day when I was trying to feed it, he wasnt interested in the snake at all, but he kept staring at only my hand. Then I accidently dropped the mouse inside his feeding box, and when I reached in to get it, he bit me! And I started bleeding. He wouldnt eat the mouse, and it seriously seemed like the whole time he wanted to bite me and not the mouse, and he never ended up eating the mouse. I tried feeding him again today, and the same thing happened, he wasnt interested in the mouse, and wanted to bite me. Its not only during feeding either. When I look at him through the glass, he strikes and hits the glass. Im starting to get too afraid to take him out, and me not taking him out isnt helping anything. :( what do I do! Im afraid hes never going to be nice again!

    Thank you!

  • PetSnakes

    Dani,

    Give her 48 hours to settle and try handling her. Usually they do fine with that amount of time. That way you can get in at least a day when you can handle her. I handle my snakes on feeding day. I handle them in the morning or afternoon and feed in the early evening. There has been no ill effects from doing so.

  • PetSnakes

    Sarah,

    The reason he bit you when you reached in to get the mouse out is pretty obvious. He was in “hunt mode”, smelled mouse, saw movement, and your hand was the moving target. As to why he’s striking at you now he’s scared and stressed. Let him alone other than making sure he has fresh water for 5 to 7 days and then take him out and handle him for a few minutes. If need be get some gloves until you get his trust back.

  • Joe

    Hi I’ve just got a corn snake on Tuesday this week it’s my first pet snake. I feed him on wednesday, he was due to be fed then, I then left him to settle in till saturday and then I handled him for the first time for about 10 mins then put him back. I’ve come to handle him again today,Sunday around the same time, and it bit me. What is wrong?

    Thanks

  • Crystal

    I have had a corn snake for over three years, ever since she was the size of a small worm. I have handled her many many times, and have never ever been bitten or even struck at. Not too long ago she decided to strike at my hand and bite me when i was reaching into the cage. It scared me badly. Nothing like this has ever happened before. Now im scarred to even reach my hand into the cage at all. Do you know a reason as to why she would have done this out of no where? (I had just fed her a few days ago, didnt startle her, didnt have on any jewlrey or lotion or anything). Could a possible reason be that she wants live mice instead of the frozen i have always given her? Does she need a bigger cage? Or is she just become more intune with her wild side and likely to bite me again?? Please help so i dont feel the need to give her away!!

  • Carlie

    Hi!

    I have a Ball Python called Freefall. We call him that because he’s a strange soul that loves to hang from the creases in the top of his tank and falls thereafter. We’re always hearing bumps as he hits the tank floor. It’s not a great height he’s falling from but why the heck does he do it? I thought Boa’s were the climbers?

    Cheers!

  • Sian

    Hello :) My royal python bit my Uncle the other day. It’s the first time he’s done so. I noticed my snake take an unusual interest in my uncles hand as he put it in the tank. Usually he doesn’t look at me when I put my hand in. I tried to pull his arm out before he struck him but it was too late. Was it just that he was in hunting mode or is there something else? I had’nt handled him other than to clean his tank for about a month before it happened…maybe thats it? I haven’t put my hand in the tank since as he’s straight on me whenever I open the top. Perhaps he associates the sound of the tank opening with the sudden appearence of a mouse?

    My uncle thankfully laughed the while thing off :)

    Thanks for help :)

    I had a beautiful pastel Boa female for several years. Recentlyshe started getting extremely aggressive — the whole open-mouthed hissing, thrashing, etc — and while I never got bit by her once she got like that I decided to rehome her.

    I have two young children. I can tail-grab almost any snake and keep out of range, but a highly aggressive 6ft boa is not something I want to risk their safety with. Herps are my passion; my family still comes first.

    I still have the rest of my herp collection which includes milks, pythons, kings, corns, and another boa (this one a docile 8ft girl).

    I made the difficult decision to rehome my boa because it was best for all of us. Boas are inherently potentially dangerous pets; I don’t need to add unnecessary risks. Even a locked enclosure didn’t justify owning something that would attack my kids.

  • Dennis

    I recently purchased a red tail boa and it was fine when i held it in the pet shop but now it continues to bite me everytime i take it out. Ive had ball pythons and red tail boas before one of the boas grew to be about 8 feet and i never got bit by any of them. When he bites i put him up and leave him be till the next day. The next day i get him out and everything is fine within 10 or 15 minutes hes striking again. If i go to open the cage and he looks agressive i leave him be. Am i doing something wrong or should i continue with the way i am goin about it?

  • Adrian

    I have a ball python, had him for almost 8 years now and hes never been aggressive up until a couple weeks ago. He bit my hand and wrapped around my wrist as if trying to subdue prey. My hand did not smell of mouse or anything. Could it just be from lack of interacting with him? I’ve been so busy with work for a while and I never get enough free time to play with him. I thought I would try to hold him today and he tried to strike me from his cage. Should I just put on a glove and tough it out till he gets friendly again?

  • arielle

    i have a snake an albino california kingsnake and he bit me a couple he bi me on my ring finger it really didnt hurt he is about 1 yr old he bit me because i didnt feed it! i feel really bad about it i didnt have the money! i am 14 and i have had it for 1 year! my dad has a bull python that is 14 ft he is about 3 or 4

  • alyssa

    I have a baby corn snake, and she hasn't bitten me for the first six months i had her. She bit me yesterday, but i think i know the reason. She had just ate, and my freind wanted to see her. I moved her rock but to put the rock back i had to move her, and she bit me. I went to her cage this morning to check on her, and she is usually curious, putting her nose to the glass. But she pulled back in a defensive mode. Is she acting like this because she is full and stressed and will she be okay once her food digests?

  • Bmiller0221

    my ball python did the same thing and yes it could be that reason he needs to get used to being handled again. so i would say tough it out. hope this helps!

  • Bmiller0221

    It is suggested that you do not handle them that much after they eat give them up to 3 days to digest. Hope this helps!

  • Eric

    your dads ball python is not 14 feet

  • Jajanes91

    I tried getting my snake out with my shirt off today, and that set her off. Thank you for the article, i never thought it would be something that simple. Oh and after finishing getting dressed she let me get her out.

    Glad it helped!

  • Sam

    I have a Mexican black king snake, she is about 3-4ft long, she is usually a really calm snake and most of the time is in her little cave, but this morning i went to get her out to clean the tank a bit and put in some food but as i went to grab her she bit me, and whenever i go near the tank she stands up (i know they don't stand but, that's the only work i can think of) at the glass and follows my hand or foot around as if she wants to attack it, can anyone help?
    she shed about 2 weeks ago i think and about 3-4 days ago i put in a new log for her to climb around.

  • http://pet-snakes.com Pet Snakes

    Were you handling food just prior to getting bit? You said you were going to clean out the tank and put in some food.

  • Tigerstripes

    Snakes purchased from pet stores aren't likely to be properly socialized. By putting the snake away every time he bites, you're basically rewarding undesirable behavior in teaching the snake that being aggressive will result in being put back in his tank. If he hasn't been properly socialized yet, this is a good thing. For him. Barring this, it could be that the move from pet store to new home was stressing him. Hopefully he's better now.

  • Sam

    no i hadn't yet got the food, it was still in the freezer.
    Literally the first thing did was to go and get her out of the tank, i wasn't able to get her out or clean the tank afterwards but i still put some food in there, she still seems aggressive though and i cant open the tank if she is out of her cave thing without her rushing towards my hand.

  • Amb_anakin

    Well if it was feeding time she probably thought your hand was food.

  • Amb_anakin

    Or maybe she needs to be fed more often.

  • Sam

    maybe but she still acting kind of funky, im gonna feed her again today then see if she lets me get her out in a couple days.

  • Donna

    My snake bit me when I was being stupid and I tried to take him out in dim lighting. I wasn't that stupid to take him out in complete dark, tere was fairly good light, but he couldn't here me and thus, I was bit. Sometimes your snakes bite you in self defense so I wouldn't start freaking out about food and all, just be careful you don't surprise them.

  • Jaseislovinit

    Hi I have a red tail boa, which I have had since she was very young – baby, now had her about 8 months maybe less and she was very tame though in the last few months I have not held her as been so busy with work and the girlfriends so not been home much -obviously I have been feeding her. I went to hold her other day and she bit me – more shocking then painful – now whenever i go near her she strikes the plastic sides and goes insane and looks savage – i can see her breathing goes crazy too – if i walk past her she follows me but basically she is consistantly striking the sides and top – i bought her a new bigger home other day and loads of cool things and myself some gloves – now i have got as mental fear to get her out….i know her bite wont hurt but it is more the unknown i think – if i attempt to start holding her daily will she become tame again? at the moment she really is striking a lot and looking menacing! Hope you can help. I dont want to sell her and i want my tame Boa back

  • Spencer5909

    Hello All
    we had a corn snake that had been in the family for years start acting this was and we called the vet, upon examining the snake he said that the reason that the snake was agressive was that it was “horny” and that if he started showing signs of the same behavior the best thing to do was put him in a slightly warm bath and let him swim around for a while. Dont know if this helps but would like to know in the future.

  • Iceprincess98

    I just got a 1 year old king snake and when the man brought it over he picked it up and gave it to me to hold no problems at all. But now i cant even put my hands near it because it would vibrate its tail and get into striking condition. I have oinly had it for about two or three days. and i already fed it too. so it being hungry is not the problem. how can i handle my snake with ease without it biteing me.

  • Wildoafi33
