Food Handling Establishments (For Use in Non-Food Areas Only)

Demon WP may be used as a general surface, crack and crevice and/or spot treatment in the non-food areas of food handling establishments.

Examples of non-food areas include garbage rooms, lavatories, floor drains (to sewers), entries and vestibules, offices, locker rooms, machine rooms, boiler rooms, garages, mop closets, and storage (after canning or bottling).

Do not use Demon WP in food areas of food handling establishments, restaurants or other areas

where food is commercially prepared, processed or served. Food areas include areas for receiving, storage, packing (canning, bottling, wrapping, boxing), preparing, edible waste storage and enclosed processing systems (mills, dairies, edible oils, syrups). Serving areas (when food is exposed and facility is in operation) also would be considered a food area.

Residential Food Areas

In the home, all food processing surfaces and utensils should be covered during treatment or thoroughly washed before use. Exposed food should be covered or removed.

Application Equipment Preparation

For best results, thoroughly wash out sprayer and screens with water and detergent before using Demon WP. To avoid sprayer clogging, do not use strainers or screens finer than 50 mesh size.


Do not apply this product in or on conduits, motor housings, junction boxes, switch boxes, or other live electrical equipment because of possible shock hazard. Let treated surfaces/areas dry before allowing humans and pets to contact treated surfaces/areas. For best results, thoroughly wash out sprayer and screen with water and detergent before using Demon WP. Do not use this product with oil. Not for use on turf being grown for sale or other commercial use as sod, or for commercial seed production or for research purposes.

Demon WP will not stain or cause damage to any painted or varnished surface, plastic, fabric or other surface when water applied alone causes no damage.

For ground application only. Do not apply by air.


During any application to ceilings of a structure, cover surface below with plastic shielding or similar material.

Do not use as an indoor space spray, such as in misters, foggers, or aerosol-generating equipment.

Use only in well ventilated areas.

Do not apply this product in any room being used as living, eating or recovery area by patients, the elderly, or infirm when they are in the room.

Do not apply to classrooms when in use.

Do not apply to areas of institutions (including libraries, sports facilities, etc.) when occupants are present in the immediate treatment area.

Do not use in warehouses where raw or cured tobacco is stored.

Do not use in warehouses while raw agricultural commodities for food or feed are being stored.

During indoor surface use, do not apply as a broadcast spray application.

Do not use in greenhouses on plants grown for food or feed, for sale or other commercial use, or for research purposes.

Do not allow applications to contact water inhabited by fish, such as in aquariums and ornamental fish ponds that are in/around structures being treated.

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.

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.
