My dad had a deplorable mice and roach problem back in Louisiana. When I was a kid, he used to tell me that he'd call roaches "cousins" back in Sri Lanka, because they invade your home, mooch off of you, and give nothing in return. A cat used to come in through the back window of my dad's house to take care of the mice. My dad never fixed that window for some reason. Darn brown hick... I recall waking up in the morning only to see that cat sitting on the kitchen sink of all places. (lol) I used to be so embarrassed to have friends over due the roach and mouse infestation, but we were all 'country rednecks,' so no one cared too much. My friends and I once watched my older brother smash a mouse to smithereens with sledgehammer; I recall its insides being various hues of green and yellow.
Speaking of my brother... He lives in Canada next to a large field, and as such, he gets bombarded with a crapton of field mice, especially during the winter. I hate those squirmy little devils. There also used to be a bigass rat that set up camp in his tool shed, but there was only the one that we knew of, so no infestation, thankfully. My brother set a match to that monster.
My aunt's basement was once overwhelmed by spiders of all shapes and sizes. I even stumbled upon a few wolf spiders down there, if I'm not mistaken. There also used to be loads of centipedes and silverfish; although, I never thought of it as an infestation. They tended to disappear when the dehumidifier was introduced every time the basement flooded.
