Demon WP Insecticide

Walt Cline - Pest Control Professional Pro Tip: "Demon WP packs are easy to use, just mix them into water. Mix well in your sprayer, and use the finished solution within a couple of days. Demon was a good German Roach killer, but they seem resistant to it now. Gel and powder baits are the best choices for the German Roach.

Cyper WSP ( packets) have the same label as Demon WP but are more economical. Both Demon WP and Cyper WSP are classified as a long-term residual insecticides.

Very good so far and just started using only 20 minutes ago
I just ordered this stuff it came in two days,today (08/5/2017) I just used 1 envelope in a gallon sprayer I wasn't even done spraying the house before roaches started falling dead.i will write a further review in the next couple of days when I see how effective it works.

This stuff works
This stuff works really well on roaches and spiders.saw roaches around trash barrels and had lots of cellar spiders.sprayed barrels and inside and outside of foundation about a month ago.just started to see a few cellar spiders now and nothing on trash barrels yet.I plan on spraying a couple times a summer from here on out.get yourself good gloves.Cheap latex ones are barely good enough.

Money Saver
I've been using this stuff for years. I spray twice a year, Spring & Fall. The only bugs I see in my house are dead ones. This stuff is amazing, I can't say enough good about it. Buy It, It Works.
