ku'u, one thing is a must --- all food products, including pet food, must be kept in tight containers. A pet water dish should be emptied at night, also.
Make sure all food waste is removed and counters wiped down.
I lived in roach heaven --- Houston, TX --- my roach problem disappeared when I started feeding the cat outside and cleaning the bowl.
"Squirt" some powdered Boric Acid behind your stove, fridge, and behind any cabinets. Also get behind your sink along the wall...Ensure you let your kids know that this stuff is not for play. You should let it sit for about a week.
The other day I was in the kitchen and I saw a 3" roach. It was skeevy. K screamed and stood on the chair.
Then a few days later, I ran into one that was about an inch and a half, in the bathroom (which is adjacent to the kitchen)
Both were really gross. The one in the bathroom I kicked to flip it on it's back so it couldn't crawl around. The one in the kitchen, we just left immediately and haven't gone back.
