I have 450 sq ft that's on the ground floor. Like almost 0 elevation at all from street level. 100 year old building. I live a 10 minutes walk away from the Pacific Coast, SF climate
Every time I wake up and go to the bathroom, I see 2-5 insects in it. 1-2 are cockroaches, rest are some other small thing. Flies maybe? Always see some cockroach droppings on sink counter that I have to spray and wipe down
Every time I leave a room dark for a few hours and turn on the lights, I always see 1-3 insects
During the day with lights on, I notice 1-4 insects per hour in various places excluding tiny fruit flies. Those I probably see like 5 times a day
Problem has been getting worse since I've moved in but this is also the first summer I've lived through in this place
And if I need pest control, how much work is it to have them come in? Should I just move apartments if I need them?
Honesltly I dunno. german roaches are very hard to kill. Can't say on the other critters if you can't ID them. Like silverfish aren't much of a problem unless they're eating your books, but carpenter ants are a big problem.
If you want to try an "organic" solution try paying neighborhood kids to bring you house centipedes (the gnarly ones with giant legs) and various spiders. idk if house centipedes can tackle a german cockroach but they'll eat everything smaller than that very efficiently.
