With roach baiting using gel baits I understand you can't liquid/aerosol treat in the same room where you place the bait. BUT, can you treat a basement with liquid AND gel bait in the kitchen? Can you liquid treat a living room on 1st floor and Gel bait a bathroom on the 2nd floor? Please define the word "area" when I read statements that say "you should not bait and spray the same AREA". Thanks for your help.
I think that a better word than "area" would probably be "surface". You would not want to apply a bait in a crevice and then apply an insecticide spray over the top of the bait, and that is probably the only conflict that exists. Our "spray" type insecticides are not volatile materials. You will not have vapors carrying the active ingredient out of cracks and crevices where you applied spray products, and have them floating around and re-depositing on bait materials in other crevices. They simply do not do that. I believe that you could place a bait in a crevice for German Roaches, since this is the preferred technique with gel baits for these roaches, and a few feet away treat other crevices with spray residual products and not contaminate the bait.
