INDOOR APPLICATION - GENERAL PESTS: Apply as a coarse, lowpressure spray or dust application to areas where pests rest, hide, travel, or enter the structure. Applications should include cracks, crevices, and voids in corners, under baseboards, storage areas, closets, around water pipes and utility openings, doors and windows, attics and eaves, cabinets, sinks, behind and under refrigerators, furnaces, stoves, and other appliances, the underside of shelves, drawers, and similar areas. Apply product as a coarse, low pressure perimeter barrier treatment (see section below) to control and help prevent infestations. Repeat as necessary.

OUTDOOR SURFACES USE - GENERAL PESTS: Apply with either a hand or power application equipment as a spray to surfaces of buildings and other man-made structures including boat house and boat docks, porches, screens, door and window frames, foundations, eaves, patios, refuse dumps, garages and other similar areas where pests are found. Use the products as a dust in cracks and crevices on the exterior in areas where pests may hide, rest or harbor. Use the product as a foam in voids, insect galleries, and other areas where product penetration and coverage may be inaccessible. This product may also be used for application to landscaped areas in and around structures where pests are active.

PERIMETER BARRIER TREATMENT AROUND STRUCTURES: Apply as a spray in a continuous band to structure foundations, around windows and doors, utility openings, vents, eaves, behind shutters, and other areas where pests may be able to enter the structure, or areas where pests congregate. To help prevent infestation of structures, apply product to a band of soil and vegetation 6 to 10 feet wide around and adjacent to the building. Remove debris and leaf litter, move or rake rocks and mulch away from the foundation and locate and move other potential pest harborage areas adjacent to the foundation. Apply as a dust in cracks and crevices in and around the foundation. The amount of product is dependent upon pest species, infestation levels, and service intervals.

ANTS AND CARPENTER ANTS: Apply as a coarse, low pressure spray or dust application to areas where ants trail, feed, and nest around doors and windows, wall voids, and any cracks or crevices where ants can enter or nest within the structure. For best results apply the product as a coarse, low pressure perimeter residual treatment and treat all nesting sites when possible to control and prevent infestations. For carpenter ants drill small holes into galleries or other infested areas and apply product as a spray, mist, or foam directly into the galleries.

BEES, CARPENTER BEES AND WASPS: Apply the product directly to nests, nest entrances, and other exterior resting areas as a residual surface treatment. On highly active nests apply product as a dust and treat surfaces where pests collect or rest with a coarse, low pressure spray. Also see “Outdoor Surfaces Use”. Nests may also be foamed with the product.

FLEAS AND TICKS: Apply product as a coarse, low-pressure residual liquid treatment to brush, rock walls, branches, tall grass areas, and other vegetation and habitat in areas where ticks and fleas may harbor. Indoors, apply as a powder to infested areas at a rate up to 2 oz per 100 sq ft. When treating carpets, vacuum carpet before application. Apply product and rake to enhance penetration into fibers. Allow the product to work for 1 to 3 days, then vacuum to remove.

SCORPIONS: Treat and remove accumulations of rocks, lumber, firewood, and other materials that serve as harborage sites. Apply product as a coarse, low-pressure residual liquid treatment to areas where scorpions hide, rest or enter structures. Also see “Outdoor Surfaces Use”.

CLUSTER FLIES AND OTHER OVERWINTERING PESTS: Apply product as a spray around windows and doors, under eaves, on siding and other areas where pests congregate or rest. Apply enough dilution to cover the affected areas, but not to the point of run-off. Apply the product in late summer or early fall before periods of heavy pest activity.

FIRE ANTS (mounds): For individual fire ant mounds, apply product as drench. Gently sprinkle a total of 1 gallon over the surface of mounds up to 12 inch in diameter and 2 gallons for larger mounds using a watering can or similar method. Pressurized sprayers may disturb ants within the colony causing them to migrate. Thoroughly wet mound and surrounding areas. Treat new mounds as they appear. All colonies in the vicinity should be treated.

TERMITES ABOVE GROUND (Excluding Formosan): This type of application is not intended to be a substitute for soil treatment. It is intended as a supplemental treatment to control localized infestations of above ground termites, winged termites and other wood-infesting insects. Apply product as a liquid, dust, or foam to voids and galleries in damaged wood and in spaces between wooded members and between areas where wood and foundations meet. Applications may be made to inaccessible areas by drilling and then injecting with a crack and crevice injector or foam applicator into the damaged wood or void spaces. Applications to attics, crawl spaces, unfinished basements, or man-made voids may be made with a coarse fan spray to control workers and winged reproductive forms of termites.

FOOD HANDLING ESTABLISHMENTS: For best results clean the area before applying treatment. Non-Food Areas: Apply product as a general surface, crack and crevice and/or spot treatment in non-food areas. Food Areas: Apply product as a crack and crevice and/or spot treatment in food areas. Exposed food, food processing surfaces, and utensils should be covered or removed during treatment. Do not apply directly to food or food -handling surfaces.

STORED PRODUCT PESTS (Exposed Adult and Immature Stages of Insect Pests): For best results clean the area before applying treatment. Product may be applied to warehouses, production facilities, storage areas, rail cars, truck beds and other areas where products are stored before filling with the product. Apply to cracks, crevices and other surfaces where pests harbor.

PANTRY PESTS (Exposed Adult and Immature Stages of Insects): For best results clean the area before applying treatment. Remove and destroy any infested food items. Physically remove any visible adults, larvae, or immature insects. Make application to pantries, cupboards, shelving and other food storage areas. Pay particular attention to cracks, crevices, shelving brackets and holes for racking or shelving units, and other harborage areas. Remove all utensils, opened food packages, shelf paper and other objects before treating. Allow treated surfaces to dry and cover shelves with clean paper before replacing utensils, and food items.

LIVESTOCK PEST CONTROL (Livestock and Poultry Housing Structures and Pet Kennels): For best results clean facilities prior to application and perform exterior perimeter treatments. Apply as a general surface and/or crack and crevice spray. Do not make applications to animal feedstuffs or watering equipment.

TURF AND ORNAMENTAL PESTS: Use product at the lower rates (1/2- 1 cup per 1000 sq ft). Mix product in sufficient water to uniformly and accurately cover the area being treated. Do not use less than 2 gallons of water per 1000 sq ft. Apply spray to the point of run-off, but do not allow excessive run-off. Be sure to treat the underside of foliage and shrubs, not just the tops. For optimum control start treatments prior to establishment of high pest populations and reapply as needed.

    It works!

    By Eileen on 07/05/2019

    I had an invasion o springtails on my kitchen counters but applying this, resulted in almost complete eradication o them! Use sparingly and use a bellows to apply. Wear a mask because it is a fine powder. The thyme oil odor is especially strong but after 2 days, I became accustomed to it! Rather pleasant odor. I'm sold on this product, especially since it's harmless to my cats and they can't stand the smell!

    Holy macaroni....this stuff is a miracle

    By Jennifer on 10/19/2019

    I am at my wit's end with cluster flies. The window sills in my house are covered every day with hundreds and hundreds of dead flies. Disgusting. I have read all over the internet how it is almost impossible to win the war with these flies....they supposedly live INSIDE the walls and attics of your home so it is impossible to get to them. But I won the war in one day with only one application of EcoVia WD!!!! WOW. I am so impressed with this stuff. I mixed it into water with a gallon-sized sprayer and sprayed the exterior walls and windows, making sure to get product into any and all cracks. Don't get me wrong....the windows are now a complete mess with white powder all over the place. But no flies anywhere. I can clean the windows later, but for now I will leave the mess and live blissfully without any cluster flies. I don't know how I got so lucky to win the war in one day, but I am buying more of this product!!!! Cluster flies house is no longer hosting you. And best of all, this product is safe for the environment and nontoxic to animals. Both a plus.

Will EcoVia WD need to be reapplied after a rain when used as a perimeter spray? How often should it be applied?

EcoVia WD should be applied when there is no rain in the forecast for 24 hours. It does not carry a long residual, so it can be reapplied as needed.  If you receive a hard rain after application, you may need to reapply.

How is the odor of the EcoVia WD compared to EcoVia EC?

The odor between the EcoVia EC and EcoVia WD are fairly comparable. While the smell of the dust is fairly pungent at first, it will dissipate as some air is circulated with it through a duster during application.

Can EcoVia WD be used to treat a home for bat bugs?

My daughters home had bats in the attic above home and garage. They have been removed by a professional in the area but now the walls have the bat bugs coming down into the house. What product can be used to kill them safely as we understand they have an 18 month life span. What may be the best way also to rid the house.


Bat bugs are treated very similar to bed bugs. Bats are their preferred host, but this does not negate them from humans. They do tend to come once the bats are gone because they are looking for a host. We would recommend using Temprid SC as a treatment for the rooms. You will mix 16 mL per gallon of water and treat in the room that has the bugs as well as all the surrounding rooms to prevent them from spreading. This will be applied with a pump sprayer. You will do this every 10-14 days until you do not see any activity for 30 days. We would also recommend using Cimexa Dust in the wall voids. You will do a couple of puffs per wall outlet and light plate with a hand duster. You will do this in all the wall voids of the home.
