Airdrop Desperate with German cockroach problem - bait gel advice?

[DavidBluet]

Hey everyone, I've been battling a nasty cockroach problem for months and I'm looking for a reliable cockroach exterminator near me because DIY methods just aren't cutting it - I've tested multiple roach killer spray reviews from online but these German cockroaches are resilient and I can spot all their cockroach life cycle stages from baby roaches to big ones which tells me this infestation is serious, plus I'm seeing clear cockroach life cycle stages explained infestation signs like droppings in my kitchen cabinets and that disgusting smell, so I'm curious about professional pest control services and their pest control cost cockroaches because I need know how to get rid of cockroaches permanently - should I use cockroach bait gel first or just contact the pros, and what cockroach prevention tips actually help to prevent them from coming back?
