It is early, but I have turned the tide against the roaches! There were scores of them, so bad that when I turned on the light there were hundreds of them!
I got a sprayer, and filled it with 1oz Gentrol, and 2 of the DEMON pesticide packs. Sprayed GOOD under the stove, refrigerator, and under the sink. Then I put out ADVANCE gel. The remaining roaches went right to it, I was watching them. I put the ADVANCE in the cabinets mostly, and the area by the microwave.
There was a fast knockdown. The ADVANCE gel works good, and I am still putting it out, but there are just stragglers now.. got to keep on them!
