I caught a mouse one night and found that there were four huge bumps on its back. I looked closer and saw what appeared to be botfly larvae in holes on each bump. I froze it and gave it to our local science teacher who dissected it with her class. Here’s a picture of what they dissected. Sure looks like a botfly to me!
I live in Fort Albany First Nation, Ontario, Canada, and I am surprised that there are botflys this far North! But is it really a botfly?

I caught a mouse in my kitchen. I come to find I was able to because it was injured. I put it into a clear cage to show the kids. I come to find the mouse has a hole in its stomach and Two protruding round items imbedded inside. Which I thought were ticks. The mouse is almost dead anyways. So I decide to keep it in the container and wait to see what happens. I check the next day after work and find the bugs detached from the mouse. Each about a half inch long wiggling around. Not really moving in any direction but just wiggling. I also showed this to a friend who’s an exterminator and he says he’s never seen anything like it, also the mouse may be a rat. If that helps. I’ve always been into bugs and snakes, etc. I have never seen anything like this before. Should I be worried seeing as I caught the mouse in the house?

Dear Matt,
Bot Fly or Warble Fly Larvae in the family Oestridae are common endoparasites in mammals, especially rodents.  The adult Bot Fly resembles a bumble bee.  From what we have read, the larvae do not kill the host, so perhaps your mouse died of other causes, or perhaps in the case of small animals, the Bot Fly Larvae can do significant damage.  We will copy Bot Fly specialist Jeff Boettner to see if he can add any information.

Possibly Mouse Droppings

Dear Jack,
Your photo does not have the necessary detail to be sure, but we do not believe this phenomenon is insect related.  We believe you have mouse droppings.  Please compare what you have to this image on the University of Michigan Museum of Zoology website.  You can also visit the Cornell University Integrated Pest Management website.  You can start by cleaning out the kitchen thoroughly and discarding any food that rodents would have access to.  If you disagree with us and still believe you have insects, please send a better photo for identification.

Dear Jack,
We do not remove content from our archives.  We do not publish email addresses unless a reader requests that for some reason.  There are so many Jacks in New York that there was no way your friends could connect this posting to you as an individual until you yourself posted a comment that included your user name.  The google search is not leading your acquaintances to our posting, but to the comment you sent as a follow up to the posting.  We can delete the comment, but we will not remove the posting.  We don’t know how much longer the cached information on your user name will lead your friends to our site, but once information has been uploaded to the WWW, it runs the risk of going viral.  It is a sad comment on the state of interpersonal relationships that your so called friends need to troll the internet with the intention of digging up dirt (or in this case mouse feces) on you so that they can publicly ridicule you.  As an aside, when we did the google search we observed that our website comes up seventh, after male enhancements and online hookups.  We fully understand how your slovenly housekeeping might reduce your internet heat factor since it might be a dealbreaker.  We believe it is best in the interest of running a family oriented website that we not only remove your comment, but also that we censor your user name from this request so that our younger readers will not inadvertently be led to the adult content associated with your internet profile.
