I used to deal with these things in hordes when I had an apartment in Bristol, VA, but lol, I'd never chop a tree just to get rid of an occasional non-destructive bug infestation. The only nuisance factor to them is their sheer numbers. Here's a good article about the bugs:

As a side note, the only insecticides we use in our house are the packages of ant baits to combat the carpenter ants that are so plentiful here in MI. I know this is gonna rub a lot of you the wrong way due to phobias, but for those of you with indoor grows who can stomach the "creepy crawlies", but if you let your house spiders and house centipedes (not the red ones but the gray/whitish, fuzzy-looking ones with the long legs that skitter all around the room day and night) do their job and don't kill them, even fruit flies will never become a major problem.
Now, I know a lot of you are going to wonder how I can say this when I am not a pest control specialist, so let me tell you a little about my qualifications... I've been an arachnoculturist for over 10 years now, at one point having kept over 500 (close to $10k worth of stock there) different tarantulas spread across about 12 different species. Tarantulas, being spiders, are very sensitive to most insecticides, and are VERY expensive for some of the harder to acquire species (Mexican Red Knee, for example... one of the most beautiful and THE most easily recognizable tarantula (think.. Black and Orange Halloween spider). Adult females sell for $300+ and live for up to 30 years or more), so pesticides have never been an option for me and I've been forced to learn to cooperate with nature, even if it means extra cobwebs around my home.
So believe me, in an area where Black Widows are non-existent and Brown Recluses are very rare (EXTREMELY scarce north of the Ohio state line), you're going to be hard pressed to wind up with anything dangerous in your house if you skip the Orkin man and let nature do the work for you.
For those of you who don't believe me about the Black Widow and Brown Recluse status in MI, read the following guide on Michigan spider species:

I really can't stress enough that insects really are our friends. We don't get overwhelmed by pests in the home until we go on an insecticide fueled rampage and destroy the beneficial residents along with the pests. In those cases, the pests are usually the ones to come back first, as the rest won't return in quantity until there's an available food supply.
We should all be more aware of our surroundings and the creatures that we share our lives with on a daily basis. With that said, know that even someone as adamant as myself about keeping beneficial species in the home will NEVER fault you for "cleaning house" so-to-speak, in the event of a serious infestation of something like Cockroaches, Termites, and Carpenter Ants, just to name a few of the more "horde-like" pests. Sometimes, the only thing you CAN do is to just kill everything and let your home "ecology" reset itself.
