So you have any pets? I did and alas I had roaches after an extended visit to GA.
Finally the cat natural died so Now it's just me, and the roaches here in my apartment. and a couple pounds of Ouroboric Acid (I used a blower to "Dust" most all the apartment. all the carpeting, Under appliances, into cracks and crevices and even the fake wood (Vinyl) flooring where I did not walk...
I now see bugs on occasion but the I may well have seen my last roach.. (It was hiding in an older microwave I brought up from the RV. Said Microwave failed dangerous (IT's an LG/Dometic and LG's do that) and is now, cordless and control paneless, in the big metal box across the parking lot (Dumpster).
The Oh-So-Boring acid just bores them to death (Word play there)
Watched one of 'em walk out onto a field of acid, he made it about 6" before ..... He decesed walking and deceased
Got Pets? The powder they use to treat pool filters (Diatomic Earth if I got the speialing right helps. not as effective as the acid but it helps.
BUG Doctor, ZEVO and other organic bug killers also work but not as well as their ads imply.
