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.

Excellent and Easy
Demon WP was just what the doctor ordered! Have not seen a scorpion since we sprayed. Thanks so much.

Excellent product
Over the past 17 years we have been fighting box elder bugs and Asian lady beetles among a variety of other random insects that like to frequent our 145 year old home. Last year a colony of carpenter ants took up residence in a 200+ yr old maple tree and soon expanded to other trees and our home. We have tried everything to win this insect battle and after ordering and applying Demon WP we only saw one bee in our attic window. We consider this a miracle, if we had only known about Demon years ago it would have saved us many hours of grief and a lot of wasted money. Thank you.

demon wp A+
long story short
we decided to move north to western maine .
after moving in we had a problem with those Japanese lady bugs
and also cluster flies, went to the box stores we bought and tried several things which to be honest had no affect.
after doing some research online we decided to buy demon wp.
all I can say is incredible! those Japanese lady bugs are no longer
and cluster flies is reduced 90% this stuff really works when applied
as directed. I sprayed around the foundation, all my eves and around the roof line.
worth every penny in my book great product.
