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?
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.
