The thing is I enjoy to kill little bitty bugs surrounded by them and I don't want to ruin them... what's the best way?
Answers:    Little bitty bugs? Are you referring to scabies? An alternative to putting the sweater contained by the dryer to kill scabies would be to disappear the sweater out of human contact for at least 4 days. Scabies cannot survive more than 4 days short having access to skin cell.

Depending on the fiber content of the sweater, it may not shrink. If it's wool, of course it will shrink. Other fibers may not be as probable to shrink, especially if you've washed and dried it until that time. And yes, high grill from the dryer will kill the little critters.

Another alternative would be to spray the sweater with bedding spray, which is commonly used to spray bedding, furniture, stuffed animals, etc. after a scabies or lice infestation. Good luck.
Throw them contained by the drier. They should be fine
