okay I got this one.... My dad used to spray house for a side hustle. __>other poster was right about orkin and their watered down stuff. They got to get their money too.
There is a product called D-E-M-O-N. it actually stands for some chemical name. It comes in 2 water soluble packets per box. You take 1 packet and drop it into a gallon of water. let it dissolve and mix by swisking it around. 1 gallon will treat 5000 sqr feet. but I treated the house every month.
THIS SUBSTANCE WILL KILL EVERYTHING...INCLUDING YOU IN LARGE DOSES.
USE GLOVES!
WheN I built my home, I was considering using boron, sulfuric acid and a number of other chemicals when my dad suggested this do it yourself DITY place for pest control. demon WAS highly recommended bc when you spray it behind appliances, piping areas, attics, garages, it leaves a light residue when it dries. Even if insect walk through it, they take it back to the nest with them or past it on to other insects they come in contact with during mating.
I have not had a roach problem ever. I gave the other packet to my cousin in the country. IT wiped out his roach problem completely. Its hard to get a hold of but if you do it works.
