Had a humongous roach infestation at the trailer I used to live in. I'll tell you what did it for me and these were the little boogers that were near impossible to get rid of. Invest in combat bait gel and bait stations. Make sure they have Fipronil. Also invest in the blue BIG jug of Raid roach spray. Fipronil is a life saver. The problem is you're spraying and only killing the few you see while there are likely thousands hiding else where. Fipronil works by the roach ingesting the poison, then slowly kills the roach (give or take 7-10 hours). In the meantime when the roach goes to the bathroom the other roaches will feast on that which contains the poison. When the roach dies the roaches feast on the carcass which has the poison too. So it is the gift that keeps on giving. When you see the roaches, don't spray but feed them the bait gel. It's the gift that keeps on giving. Bear in mind this takes a few weeks to fully cycle through, but, be diligent about laying the bait. We did this on a house where we would wake up with roaches on us and would've put the houses on Billy the Exterminator show to shame. Tried Borax and no luck. But definitely give the Combat bait gel a shot as the DIY places sell the same stuff but it's called MaxForce and costs 2 to 3 times more. Also once you have the infestation under control check out a product called Demon WP. It's a great barrier spray. Let us know how that works out for you
