Demon WP Insecticide will kill adult fleas outdoors only 1-2 days after the lawn is mowed. It is mixed at 1-2 packs per gallon of water per 1,000 sq ft. Please take a few moments to review our article/videos on How to Get Rid of Fleas for a successful eradication program.
Demon WP Insecticide can be applied every 21 days as needed.
Demon WP is a great choice for spider control. Demon WP is a wettable powder that is diluted in water, and then sprayed around door frames, window frames, in areas where utilities (cables, pipes, wires) enter into a structure, around the bottom of the foundation and other area where insects are known to harbor. Demon WP can leave a white powdery residue on dark surfaces. If the powdery residue is a concern, you can choose a micro-encapsulated product such as Onslaught Fast Cap Spider and Scorpion.
No, the Demon WP would not have any effect on the eggs produced by the chickens. There is such a small amount that would be in their system that kills them it would be eliminated by the time the chicken would come in contact with the roaches. The chickens would however need to be completely out of the area while you are spraying the Demon WP initially and until the product completly dries.
