Product Overview

DeltaGard Insecticide is an ultra-low volume premise spray for the control of flies and mosquitoes in and around poultry and livestock facilities with the animals present. The formulation allows for dilution with water rather than oil and provides quick knockdown of flies and mosquitoes. DeltaGard has a Film Forming Aqueous Spray Technology (FFAST), that reduces water evaporation with the use with hand-held, backpack, portable and truck-mounted ULV equipment.

May be applied undiluted. To maximize efficacy against larger fly species (blow flies, filth flies), the recommendation is to dilute in water (1:1) before application, increasing the droplet density in the ULV cloud.

How-to Videos:


DeltaGard Insecticide is approved for application as an Ultra-Low Volume (ULV) aerosol to control flying or resting adult flies in residential, industrial, urban, recreational, and municipal areas where flies are found. This product is used for control of flies in areas such as residential areas, industrial areas, urban areas (such as utility tunnels, sewers, storm drains and catch basins, pipe chases, basements, underground passages, parking decks, crawl spaces, or uninhabited buildings), parks, campsites, woodlands, athletic fields, golf courses, playgrounds, recreational and overgrown waste areas, roadsides, swamps, marshes, tidal areas, corrals, feed lots, swine lots, poultry ranges, zoos, animal quarters, barns, dumps, junkyards, tire dumps, and other areas where adult mosquitoes and flies may be found.

DeltaGard is recommended for application with hand-held, backpack, portable, & truck mounted ULV sprayers and portable and vehicle mounted mist-blowers for area applications, to control, black flies, gnats, non-biting midges, stable flies, horse flies, deer flies, sheep flies, horn flies, and nuisance pests such as face flies or blow flies. Spray equipment must be adjusted so that the volume median diameter (VMD) is between 8-30 microns and that 90% of the spray is contained in droplets smaller than 50 microns.

For the treatment of livestock and poultry facilities (e.g., cattle, dairy and livestock barns, goat houses, horse stables/barns, loafing sheds, poultry houses, shade houses, stables, swine houses, feedlots, manure piles, swine yards, corrals, stockyards, holding pens, and other animal facilities) where flies become pests and quick knockdown is needed.

Indoors, reduce air movement as much as possible before applying by closing doors, windows and other openings; if animals are present, ventilate the treated area immediately following application.

When treating indoors, cover any exposed drinking water, drinking fountains, and animal feed before application. Outdoors, apply when insects are most active, usually in late afternoon when there is little wind. Pay particular attention to areas where flies congregate, such as around feed bunks, fences, and on the exterior walls of buildings.

Animals may be present during treatment.

If treatments are made with animals present, the maximum number of applications per year depends on the application rate used; 10 applications at 0.00134 lb. ai/A, 15 applications at 0.00089 lb. ai/A, or 30 applications at 0.00045 lb. ai/A.

    Customer Service

    By Lorraine on 08/22/2019

    I ordered this product for mosquitoes. I was having an outdoor function. The USPS made a mistake and miss delivered the product. I called customer service and they went beyond my expectations. They re-sent me the product. Although I did get it on time I am very pleased with this company. I have ordered from them before and will continue to order from them.

How many ounces of DeltaGard Insecticide do you use per gallon of water?

DeltaGard Insecticide may be applied undiluted.  If diluting then use at a 1:1 ratio.  Meaning if you use 8 ounces of DeltaGard Insecticide then you would use 8 ounces of water mixed with that for ULV application.  Please refer to the product label for more detailed application rates and mix ratios for differing applications.
