When treating for roaches, we recommend using a bait, a liquid insecticide and an insect growth regulator (IGR). You are able to treat with all 3 of these products at the same time, just not on top of each other. For instance, our Roach Control Kit # 2 has all 3.
The Demon WP is for crack and crevice treatment around baseboards. Dilute 1 packet per gallon of water in a pump sprayer and apply in cracks and crevices where pests are seen, may harbor, or may enter the structure (corners, baseboards, and under and behind appliances) Do not spray on top of baits where bait will be used.
No, Demon WP is not labeled for bed bugs.
We would recommend using Temprid SC. For your first treatment, you will use 16 mL per gallon of water and spray around the baseboards and cracks and crevices in the rooms where bed bug activity has been found. You will do follow up treatments every 10-14 days until there is no activity for 30 days. We would also recommend using Cimexa dust inside the wall voids. The bed bugs will walk over the dust and dry out. This can be applied with a hand duster. We would also recommend treating your mattress and box spring directly with Bedlam Insecticide. You will treat the tufts and seams of the mattress where bed bugs are likely to reside. Our Bed Bug Guide is a wonderful guide that we provide as well.
We would recommend contacting your veterinarian as soon as possible. They would better be able to give you advice on your cat.
We do recommend keeping your animals out of any area that was sprayed until Demon WP and any other product is completely dry.
