Bengal UltraDust 2X Fire Ant Killer, manufactured by Bengal Products, is a ready-to-use, dry insecticidal dust that targets fire ants and a wide variety of other crawling and stinging pests outdoors around homes and ornamentals for up to 8 months.
It contains 0.1% Deltamethrin, a powerful synthetic pyrethroid that acts as a neurotoxin for insects, which paralyzes and kills them with contact or ingestion. Unlike ant baits that can take days to be effective, this dust begins eliminating the colony within hours by allowing worker ants to carry it back to the queen. It kills the queen, fire ants, and destroys the mound overnight without the need for watering in, and without clumping or absorbing moisture.
Bengal UltraDust 2X Fire Ant Killer is a twice-the-strength insecticidal dust that provides long-lasting protection against a dozen pests, making it a standout solution for total yard and perimeter control. With its easy-to-use shaker top, applying the dust is simple and mess-free, making it ideal for both quick treatments and long-term pest control.
Tools Needed
This product is intended for applications from the shaker can, so additional tools are needed.
To treat ant mounds, you may use a chemical purpose teaspoon.
How to Use
- Step 1: Determine how much Bengal UltraDust 2X Fire Ant Killer to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). Evenly sprinkle one teaspoon (approximately 1/6 oz.) of Bengal UltraDust 2X Fire Ant Killer over the top of each ant mound. For shrubs and ornamentals, apply 4 ounces of prdouct per 1000 square feet.
- Step 2: Carefully twist off the protective cap on top of the shaker canister and peel the foil out. Screw the cap back on securely, and it will be ready for controlled dust application. You will need to remove the protective cap to evenly scoop up with a teaspoon.
- Step 3: Apply the dust directly over the top of the ant mound until it's evenly applied. Make a residual treatment around windows and doors, porches, screens, eaves, patios, garages, under stairways, in crawl spaces and other areas where pests hide. To help prevent the invasion of buildings and structures by these pests, apply thoroughly and uniformly to the foundation and crawl spaces where pests are active and may find entrance. To treat shrubs and ornamentals, thoroughly apply to place a thin layer of dust on both upper and lower sides of leaves, stems and flowers.
- Step 4: Reapply as necessary for ants. For other pests, repeat at 7-day intervals or as long as insects continue to appear.
