Product Description:

Arm yourself against ants and other annoying pests with this unique, ready-to-use TERRO® Ant Dust. The waterproof dust won’t wash away in the rain and will remain effective up to eight months. Ideal for crack and crevice treatments, TERRO® Ant Dust can be used both outdoors and indoors.

Outdoor Use

Outdoors, apply TERRO® Ant Dust around windows and doors, porches, screens, eaves, patios, garages, under stairways, in crawl spaces and other areas where pests like to hide. To help prevent indoor invasions, apply TERRO® Ant Dust thoroughly and uniformly to foundations and crawl spaces where pests are active and may find entrance to your home. To treat fire ant mounds, evenly sprinkle approximately one tablespoon of TERRO® Ant Dust over the top of each mound. Do not water in or disturb the mound. Apply when temperatures are between 65° and 80°F and allow three to four days for maximum control. Repeat application if ants are still active.

Indoor Use

Apply TERRO® Ant Dust as a surface, spot, or crack and crevice treatment, to indoor areas where insects crawl and hide.  Apply the insecticide lightly and uniformly from the convenient, easy-to-use shaker can, or place into cracks and crevices using a bulbous duster, paint brush or other suitable means.

Pay particular attention to service ducts; wall voids; areas around electrical equipment, water and sewer pipes; under and behind cabinets, refrigerators and sinks; around windows and door frames; along baseboards; and in attics and crawl spaces.

For the treatment of ants, apply TERRO® Ant Dust to ant trails, around doors, windows and other places where ants are found entering the premises.

The amount of ant dust to apply will vary with the site but should typically be in the range of 0.5 lb of product per 1,000 square feet.

    What a blessing after decades of try to find the right product. By Kurtly

    Kills Box Elder Bugs! This is the only thing that I have tried that will kill Box Elder Bugs. It does it fast too. It worked so well that one dusting of the perimeter of my house and garage made a significant disappearance of all the bugs that used to climb up on the sunny side of my house by the end of the day!. We used to be almost plagued with the bugs coming into the house every winter but I dusted every 2 months around my house and have only seen 2 bugs this winter, I thing it will take a few years of dusting and clearing out ash and silver maple trees to completely rid the nuisance but I am utterly amazed at the difference already!

    Works great!! By Kris

    After a week of 90 + degree heat the sugar ants in the crack between my driveway and garage have multiplied like crazy. I woke up one morning to find 100s in my kitchen just off the garage, and my garage floor had thousands crawling around. I sprinkled a decent amount of this in the cracks around the area and hit the ants in the house with raid, still leaving some behind because I had to go to work. My wife got up a couple hours later and there were no ants anywhere. After a second week of 90 degree weather I still have not found a single ant in this area. Love this stuff!

    Very Satisfied By Marco

    I used Terro Ant Dust for years in combination with other pesticides like Terro Ant Bait and much more. Works great and last long along with it being waterproof. I live in a heavy wooded area and for the last 25 years I have been keeping carpenter ants along with others at bay.

    Long lasting effective ant control product By Golpher

    This is the best long lasting ant killing product by far. We have a big ant problem at houses at the Jersey shore and I found this powder keeps the ants away, and lasts for a good while. The ants walk thru the powder and take it back to the nest where these social insects "groom" each other, all taking some of the poison and then dying. The only problem I'm having now is finding a place to buy it (retail, not online). I've tried Home Depot, Lowe's, Targets, but while they all carry some Terro products, they don't carry this Ant Dust. Any suggestions? (really don't want to pay S&H).

    Terro ant products are the best By Ant-i

    I've used Terro ant dust, liquid bait, and granular bait to combat carpenter ants and they are by far the most effective products.

    Not really waterproof, but highly effective. By Al

    This product works - period. After repeated seasonal "invasions" by small ants I began using it as full perimeter protection around the exterior of my house, from beginning to end of the ant season. As long as I am careful to maintain fresh powder, there are no ants inside the house. As soon as ants hit this barrier they are sorry they tried. Also stops some other crawling insects as well. I only gave it four stars instead of five because, although the product is touted as "waterproof," rain will diminish its effectiveness and eventually wash it away, requiring re-application several times a season. This gets expensive. Nevertheless, fresh powder goes down and the ants stay out.

    Q.I’m installing a new paver patio. There is an ant infestation along the wall where pavers will be installed. I’ve just sprinkled the dust along the wall and hoping that it works. I’ll probably have to retreat same area in future and would like to know if the ant dust will damage my new pavers

    This product can be used on patio's. We recommend keeping the dust  contained to cracks and crevices.

    All About


    There are more than 10,000 known species of ants living throughout the world. Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae and powerful jaws. Ants are social insects that live in structured nest communities throughout the world. The species of ant determines whether they live underground, in mounds built at ground level, in wood structures or in plants or trees.

    More About Ants


    How do I keep ants from entering my house?

    Since most ant infestations are linked to a colony that is located outside the house, the first line of defense is setting up a barrier around the perimeter of your house with TERRO® Ant Dust. The waterproof dust kills pests on contact and provides long-lasting, 8-month repellency.

    What product do you recommend for killing Fire Ants?

    TERRO® Ant Dust is an effective way to control fire ant infestations. The ant dust kills pests on contact and will continue killing up to 8 months, because the unique waterproof formula won’t wash away in the rain.

    To treat fire ant mounds, sprinkle approximately one tablespoon of the Ant Dust over the top of each mound. Do not water in or disturb the mound. Apply when temperatures are between 65° and 80°F and allow three to four days for the product to control the ants.
