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.

Not a bug in 3 years!
I battled ants in my kitchen and bathrooms and was beginning to see small roaches and an assortment of other pests in my garage. For three years now my house and garage have been bug free.

This product is virtually odorless, non-staining and very easy to use.

Unbelievably effective!

BUT do not get carried away and use it on your plants in the garden. I saw from the label that it could be used in the grass and no harm was done. It completely wiped out my beds of well established and previously healthy english ivy. (Not smart on my part!)

Best stuff I ever used
Used for carpenter ants and scorpions. Fantastic. Collateral action on other insects and spiders. Well worth the money.

I have been buying this product since the mid 90s and found it to work great. Friends and family that I introduced to it have agreed it is awesome.
