    Demon WP may be used as a crack and crevice and/or spot treatment for indoor surfaces use. Cockroaches, Spiders, Crickets, Scorpions, Silverfish, Ticks, and Firebrats

    Apply as a coarse, low pressure treatment to areas where these pests hide, such as baseboards, corners, storage areas, closets, around water pipes, doors and windows, attics and eaves, cabinets, furniture, sinks, furnaces, stoves, behind and under refrigerators, the underside of shelves, drawers, and similar areas. Pay particular attention to cracks and crevices. Also see Outdoor Surfaces Use.


    Apply to any trails, around doors and windows, and similar areas where ants (including carpenter ants) may be found. Where ants are trailing inside, apply as a residual surface treatment to active areas such as baseboards, corners, around pipes, in and behind cabinets, behind and under refrigerators, sinks, furnaces and stoves, cracks and crevices. When combining baits and residual surface insecticides, apply surface insecticides in cracks and crevices, along baseboards, and infested surfaces and outside barrier treatments. Apply perimeter barrier treatments and treat nest to prevent infestation as described in Outdoor Surfaces Use.

    Assassin Bugs, Boxelder Bugs, Sowbugs, Pillbugs, Millipedes, Elm Leaf Beetle, and Centipedes

    Apply around doors and windows and similar areas where these, or similar perimeter pests, may be found or where they may enter premises. Apply to baseboards, storage areas, and other locations.

    Apply perimeter barrier treatments to prevent infestation as described in Outdoor Surfaces Use.


    Apply with either hand-held or power application equipment as a residual spray to surfaces of buildings, porches, screens, window frames, eaves, patios, lawns, refuse dumps, garages and other similar areas where these pests are found. Also, may be used as a spot treatment in applications to lawns in landscaped areas in and around residential, commercial, institutional and industrial buildings, and similar areas where these insect pests are active.

    Carpenter Ants

    Apply as a coarse wet spray treatment, but avoid runoff around doors, door frames, windows and similar areas where these ants enter premises or hide.

    Fire Ants (Mounds)

    For individual fire ant mounds, apply Demon WP as a drench. Gently sprinkle a total of one gallon over the surface of mounds up to 12 inches in diameter. Use 2 gallons for larger mounds. Thoroughly wet mound and surrounding area. Treat new mounds as they appear. Pressurized sprays may disturb the ants and cause migration. If possible, applications should be made on warm days after recent rainfall. All colonies in the vicinity should be treated, including those that have not yet constructed a mound.

    Bees, Flies, Mosquitoes, and Wasps

    Apply directly to walls, window screens, and other exterior resting areas as a residual surface treatment.

    Use caution when treating nests of stinging insects as Demon WP does not provide instant knockdown. Protective equipment for the applicator may be required. For best results, treat bee, wasp and hornet nests late in the day when most insects will be present. Allow 2-3 days for colony to die.

    For mosquito control, apply as a general structural perimeter spray to landscape plantings, turf, and building foundations to control mosquitoes. Yards or other frequented areas enclosed by landscaping can benefit from the creation of a mosquito barrier to reduce invading mosquitoes by the treatment of perimeter vegetation. For best results, apply Demon WP at recommended rates in 2-5 gallons of water per 1,000 sq. ft. Higher volumes applied result in better coverage and, as a rule, will improve control. Application to vegetation away from structures may require additional applicator certification, e.g. in turf or ornamental categories. Consult your state regulatory agency for requirements. Not for use in wide area mosquito abatement programs.

    Fleas and Ticks

    To control nuisance fleas and ticks (e.g. dog ticks) apply to yards, runs, and other outside areas where pets may frequent. To control ticks, apply using a coarse fan spray to vegetation brush, branches, rock walls, and other areas near habitation where ticks may harbor or frequent. Treat entire area rather than making spot treatments, and retreat as necessary to maintain control. Do not apply to pasture or cropland, and do not allow animals and people access to treated areas until the deposit has dried.

    Applications can begin in the spring and can continue until frost to control both larvae and adult ticks.

    Cluster Flies

    Make exterior treatments in late summer or early fall before flies are observed alighting on surfaces.

    Apply thoroughly on siding, under eaves, and around windows and doors, paying particular attention to south-facing surfaces. Apply just enough dilution to adequately cover the area without excessive dripping or runoff. Heavy precipitation prior to frost may require re-treatments to maintain protection. Scorpions

    Treat and remove accumulations of lumber, firewood and other materials that serve as harborage sites. Apply as a coarse spray treatment to the point of drip.

    Sod Webworms

    Apply as a spot treatment when pests first appear (do not apply as a broadcast spray). Delay watering or mowing the treated area for 12-24 hours after treatment. Use 1-5 gallons of solution per 800-1,600 sq. ft. when making application. Retreat when needed but not more than every two weeks.


    Applying a continual band of insecticide around a building foundation and around windows, doors, service line entrances, eaves, vents, and other areas can greatly reduce the potential for entry by crawling pests. To facilitate application, remove debris and leaf litter from next to the foundation, trim vegetation and branches that touch the foundation, and move or rake back rocks, deep mulch, or other potential pest harborage next to the foundation. To help prevent infestation of buildings, apply as a band to soil and vegetation 6-10 ft. wide around and adjacent to the building. Also, treat the building foundation to a height of 2-3 ft. where pests are active and may find entrance. Apply as a coarse spray treatment to thoroughly and uniformly wet the band area, using 1-5 gallons of treatment solution applied to 800-1,600 sq. ft.

    Amount of concentrate is dependent upon pest species (see pest table and comments), infestation levels, and service interval desired.

    Excellent flea killer.
    Tried Demon a few years ago because of a flea problem and Demon killed all the fleas, inside & outside. Continues to kill fleas and everything else for months. 98% smell free and safe for inside use. Very good product.

    Works great
    I've been using this product for a long time. So long I forgot how many years. It works great both inside and outside around the house. I'm glad I found y'all because it was becoming cost prohibitive for me to go to the local farm and ranch store. Y'all made it possible for me to save enough money to buy my annual amount of Demon WP. Thanks a bunch. Now if I could get a recommendation for a product that would deter varmints such as skunks, 'coons, possums from digging under my house I would appreciate it. Thanks again.

    works great for scorpions
    After getting stung one time in the middle of the night, I have been using this in and around my deer lease trailer for the past couple of years. It works great and on the rare occasion I see a scorpion in the trailer, he's already dead. It also kills pretty much anything else. So that also helps to keep the scorpions away.

    This stuff works
    I love this product, I use it all year round. I had black widows and centipedes, after spraying this within few hours they would be dead. Highly recommend !

    Best Insecticide I've ever used!
    If your looking for something that you can barely smell and definitely kills any kind of insect then Demon is your answer! I've been using it for years and once you spray an area you can rest assure that nothing will live if it crosses the barrier. Even after several hard rain storms it still is very effective. Month after month you will still see it's killing power. You will see lot's of dead bugs thats for sure.
