I shot a squirrel with 2 warbles. Anyone having warble problems this year?

Not to sound stupid but that are they?

a warble is a botfly larva, the fly lands on the squirrel and bites it, laying the egg between the skin and the muscle. as the warble grows a large mound appears. when the warble reaches maturity it breaks the skin and comes out. they are common on rabbits also here's a picture of one.

ewwww lol i saw a show on tvonce where a guy popped one of those out of a cow like it was a living wriggling zit, grossed me out then and i guess it still does. ive yet to shoot any yet this yr though, so idk if they'rea problem i dont even know if we have em here in WI
