Reduce infestations of common home and garden pests with this TERRO® Outdoor Ant Killer Spray. Summertime means many home and business owners are plagued with outdoor insects coming indoors, including ants, carpenter ants, cockroaches, spiders, and other smaller creeping pests. Keeping outdoor pests from entering your home or business is easy with this killer ant spray.
Kills Ants and Other Insects
This TERRO®
spray is created to kill many different kinds of outdoor pests that spread disease or cause painful, inflamed bites. This includes ants, carpenter ants, cockroaches, spiders, and other insects.
Fast Knockdown Protection with Long-Lasting Residual Control
Prevent the insects from scattering with a patented blast system that knocks them down fast. For the squeamish, you can kill the insects without coming near them. Simply place the attached extension tube to the nozzle for long-distance use. This powerful TERRO® spray can reach up to 15 feet away, letting you remain at a comfortable distance.
Use as a Spot Treatment or in Cracks and Crevices
TERRO® Outdoor Ant Killer Spray may be used to prevent an infestation in your home. Simply apply to cracks and crevices, reaching deep within to reach where ants and spiders like to hide. You can also use this along the foraging trails that ants follow into your home or apply directly to anthills. To protect your house or business, spray along the perimeter of the building as a barrier for insect pests.
Aerosol Can Designed for Outdoor Use Only
This potent spray is designed for outdoor use only. Use caution when spraying in the wind, as blowback may be harmful. When sprayed, the outdoor ant killer expands upon hitting the surface and leaves an invisible residual deposit.

Unhappy with the sprayer. Foam does not come out little red straw but foam squirts out the top and sides. All it made was a mess. I can’t get my money back as I don’t have a receipt. Just wanted to voice my frustration trying to use it. Terro trays work good for inside.

I only use this ant killer as it stay potent for quite a long time-/outside. I spray it around each window and door frame and around wall air conditioners once in May and then once in August. That’s all it takes !! Worth the little extra for a spray can with pinpoint accuracy. Thank you!
Change in product spray caused low rating, not effectiveness.

I've used this product for years, and it's always done the job well. This time, I ordered direct from the Terro Website, and what I received wasn't the same spray. Previously it was an actual fine mist spray that came out of the can. This latest stuff is more of a foamy liquid. It splatters all over the place, and makes a big mess. It still kills the ants, but I'm very unhappy they didn't update the product labeling to indicate this change. The first time I used it, it splattered all over and saturated some wood surfaces I didn't want to get wet.

I have used this product for a very long time an it is far an away the best I have EVER used. The long distance spray is great for around window's etc.
I used the Outdoor spray, I did not see ants for a few days but now I see them again. I am not happy with the outdoor. I will keep observing my second can and see if I see any difference. The can emptiest very fast, does not give much product for the money,.
This product is effective after application, and ants that come in contact with the treated area will still die withing 24-48 hours. We appreciate your feedback and have shared your comments with our Product Managers. This product is covered by our 30-day guarantee and a 1-year replacement policy. Please contact our Consumer Relations Team at 1-844-837-7644 for assistance, we're happy to help.

Tero Outdoor Ant Killer (& all their ant products) are FABULOUS!! I live in an area (Bay Ridge, Brooklyn) that is loaded with tiny brown ants. Any home owner can tell you of their battles with these persistent little critters. For years, I couldn't keep my kitchen window open at night due to the risk of them coming in (one evening I found a trail from window, across kitchen to my pantry) and my upstairs tenant had the same issue. Tero was recommended by my exterminator brother and it is the ONLY product that has kept the ants at bay. Thank God for Tero!!
Very disappointing. I have used a few of these cans and although the spray will kill the ants it doesn't seem to last even a day at times. After I spray the ants will be back either later that day after the spray has dried or the next morning in full force. It does not kill the ants or stop them near as long as they say on the can unfortunately.
How long does this product continue to be effective, before one needs to reapply?
Question by: Peter on Oct 17, 2024, 7:50 PM
This product should be reapplied after it rains.

Have Asian Lady Bugs.
Saw answer to reapply after rain, but between rain how long does product last?
If area not exposed to rain (underside attic ventilation vent/soffit ventilation) does it lose its effectiveness?
Question by: Lew Warren on Sep 27, 2025, 12:29 PM
Hi, thank you for reaching us. The product provides long-lasting residual repellency and protection for up to 12 weeks after application.

When I searched your site for “Asian Lady Beetles (or Bug)” Terro Outdoor Ant Killer (T1700-6) product did not come up, but it is listed on the label, etc. Terro Ant Killer Spray T2303 came up, both list Asian Lady Beetles. Which lasts longer and is most effective?
Question by: Lew Warren on Sep 27, 2025, 12:44 PM
HI, thank you for reaching us. Both are equally effective. However. The TERRO Spider & Ant Killer Spray (T2303) continues to kill insects for up to four weeks and can be used indoors, while the TERRO Outdoor Ant Killer (T1700-6) is an outdoor use only product that would last up to 12 weeks after application.

Just bought this product. Can will not spray at all. Am I doing something wrong?
Question by: Cullen Cacicedo on Jun 29, 2025, 10:04 PM
Thank you for reaching out, and we're sorry to hear you're having trouble using your new TERRO® Outdoor Ant Killer Spray. The can should begin spraying when the nozzle is pressed firmly, but sometimes the spray mechanism may need a few steady presses to activate if it’s a new or recently manufactured unit. Please ensure the nozzle isn’t clogged and that the straw, if included, is properly attached. If the product still does not spray after trying these steps, the can may be defective. We apologize for the inconvenience and would be happy to help resolve this. Please let us know where and when the product was purchased so we can assist you further.
