We have always had out unit pest controlled by a pest control company. Due to living in an extremely humid city, we have had to call out the guys a few times in their 1 year of warranty do deal with recurring cockroaches. The only thing that bothers us is cockroaches.
Our unit is clean and there is barely any clutter and no food left around etc. This time around the pest control guy just came in and sprayed something on the bottom and top of the boundaries on the walls with his magical spray. "I have sprayed your house with blah and that should take care of them all"
I am thinking, I can get that chemical/spray and do this myself. Has anyone done pest control of their homes themselves ? If so, what did you use and how did you go ?
The usual Mortein/etc baits and mist sprays etc dont work.
If you can, call the pest company and say you’re worried about the toxicity of what they’re spraying. Ask them to supply a Material Safety Data Sheet (MSDS). Its a pretty standard document, but it should tell you exactly what they use - then you could figure out where to source it from.
