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?

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

  • 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.
  • 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!

    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
    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!

    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?
  • 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!

    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?

    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.

    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.

    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 :)
