TERRO® Outdoor Ant Killer Spray
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.

Purchase 2 cans of : ...

Purchase 2 cans of : Both sprayers immediately failed.
Sounds like the TERRO® Outdoor Ant Killer Sprayers are mostly negative about the ineffective nozzle and sprayer.
I should have done some research prior to purchase..

Thank you for sharing your experience. We apologize for the frustration caused by the sprayers not working as expected. The TERRO® Outdoor Ant Killer Spray is designed with a dual-action nozzle that can be adjusted for different spray patterns, and in some cases debris or product buildup around the nozzle may affect performance.
For best results, ensure the nozzle is fully rotated into the desired spray position and check for any blockage around the opening. We understand how disappointing it is when a product does not perform as intended, and we appreciate your feedback regarding the sprayer design, as it helps us identify areas for improvement.
Sprayer clogs
Apr 28, 2026
I like the product but the sprayers clogged on 3 of 4 cans purchased. I called 844-837-7644 on 4/28/2026 about this, and Alex planned to send me a replacement for one of the cans. That's good, but then he said they don't have any in stock. In fact, he said, they don't have any of their ant sprays in stock. I asked for a coupon instead. He said they don't have coupons. He told me to call back in a week. This is absolutely lousy customer service. I have spent hundreds of dollars on Terro products, and this is all they can do. The problem was pushed back on me. Pitiful.

Don’t like sprayer
May 29, 2021
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.
Long lasting potency
Apr 5, 2021
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.
Feb 24, 2021
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.

Q&A
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.
Answer by: Kristen on Oct 18, 2024, 8:00 AM
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.
Answer by: Guillermo (Admin) on Sep 29, 2025, 9:39 AM
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.

Is TERRO® Outdoor Ant Killer Spray safe for cats and dogs
Question by: Kathy on May 29, 2026, 4:31 AM
When used as directed and allowed to dry completely, TERRO® Outdoor Ant Killer Spray is safe for use around pets. To help protect cats and dogs, keep them out of the treated area during application and until the spray has fully dried. Always follow the label instructions for best results.
Answer by: Walter Sandoval (Admin) on May 29, 2026, 9:24 AM
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.
