Demon WP is labeled for both indoor and outdoor use. Apply Demon WP to exterior door frames, window frames, places where utilities (cables pipes and wires) enter into the structure, eaves, soffits, around the bottom of the foundation and out onto the ground several feet. If you have an existing insect infestation, you may also need to spray indoors around the door frames, window frames, places where utilities (cables, pipes and wires) enter into the structure and around the baseboards. Demon WP will last for about 4 weeks outdoors and about 12 weeks indoors.
Demon WP is not a problem to use around pets as long as you apply it according to the product label. Once Demon WP is mixed with water, it is only strong enough to kill small insects. You would not want to leave the jar of Demon WP open where dogs could get into a large quantity of it. It is always a good idea to keep pets and children out of the area while you are treating. Once the product dries, usually after 30 minutes, it is perfectly fine to allow pets and children back in the area. However, all pesticides are very dangerous to fish and aquatic life. You would not want to use Demon WP or any other pesticide near a body of water. 50 yards away is a good distance, but if the land sloped down towards the pond, then there may be a concern. If it does not, it should not be a problem to treat around your home that is 50 yards away from the pond.
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.
That is a hard question to answer because both work very well. However, we do sell the Demon WP in our Roach Control Kits and it does work a little faster and provides a punch for quick knock down. Sprays alone usually do not work. You should use this along with a Roach Bait so the roaches have something to take back in the walls and other hiding places that you do can not spray. Our Roach Control Kits have a very high success rate and incorporates sprays and baits.
