Demon WP Insecticide is a great product but yes, it is always a good practice to alternate products with different active ingredients. Resistance can take a few years to become an issue but you can switch between chemicals every 30 days, on a yearly or two year basis, no longer than that, to avoid any issues.
Yes, Demon WP Insecticide may be used as a crack and crevice treatment for general pest control in homes with children. Pets and children should be kept out of the area while the product is being applied and until it has thoroughly dried.
The mix rate for Demon WP Insecticide is 1-2 packets per gallon of water. You would need at minimum 25 packets added to 25 gallons of water. You may want to look at Demon Max, which has the same active ingredient, but it is a liquid concentrate so it may be easier to mix for larger applications.
Demon WP Insecticide when used inside is only applied to cracks and crevices. It could be used in the drop ceiling around vents and other entry points that allow insects in.

While the Demon WP is a great insecticide and covers a wide range of insects, it would not be our best recommendation for control of grubs and other insects the moles would feed on.
Merit Granules are most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.
Dylox 6.2 Granules is only active and kills for 48 hours. Dylox should be watered in for at least 1 to 1.5 hours for best results to ensure the product makes it through the thatch layer to where the grubs are feeding. Mature grubs usually require at least 2 applications, 3 to 4 days apart.

Demon WP Insecticide is not labeled nor would it be recommended to treat a pantry for moths. The best way to eliminate pantry moths is to find the infested food items and dispose of them immediately, then thoroughly clean the infested cabinet. The moth larvae (immature moths) can usually be found in grain products such as pasta, rice, flour, or spices. The adult moths and wandering larvae can be killed with D-Force Insecticide. The active male moths can be lured and trapped with the ProPest Pheronet Pantry Pest Traps. We have put together a Pantry Pest Kit that contains everything you need to get rid of the pantry moths.
Demon WP Insecticide specifically states on the product label for Outdoor Flea Control only. It cannot be used inside homes for fleas. When Demon WP is used inside correctly for the listed insects it is only applied to cracks and crevices around rooms, along baseboards and cannot be used across entire floor surfaces where you would need to treat for fleas. Precor IGR would be a great part of treatment along with an insecticide such as Onslaught which can be used on carpets. We also have great guides here for identifying, inspecting and treating fleas to ensure you are correctly treating.
Demon WP is a professional grade product and is not sold in retail stores. You can purchase it through us, online or over the phone, and we offer free shipping. We are available at 866-581-7378, M – F 9 am – 5 pm ET.

It is always a good practice to alternate products with different active ingredients. Resistance can take a few years to become an issue but you can switch between chemicals every 30 days, on a yearly or two-year basis. A great alternative to Demon WP would be something like Suspend SC. Suspend SC is a general insecticide that is labeled for various pests, including roaches, mosquitoes, ticks, fleas, etc. This can be used indoors and outdoors around the perimeter of your home. We would recommend 30 days between applications of different products.
Demon WP is not labeled for gnats. We would recommend Bifen IT instead. You may also want to look over our article on Getting Rid of Gnats for more information.
