Product Description:

Keep ants from entering your house with TERRO® Outdoor Ant Killer. Our best outdoor ant killer provides instant knockdown and long-term control against ants and other unwanted home invaders. An easy-to-use, powerful spray head allows you to deliver barrier spray in hard-to-reach places up to 10-15 feet away. When sprayed, the liquid outdoor ant killer expands upon hitting its target surface and leaves an invisible residual deposit.

TERRO® Outdoor Ant Killer is the best outdoor ant killer product on the market. It's ideal as a perimeter barrier around foundations, doors and windows. It is especially usefull outside in early spring when ants emerge and attempt to enter the house. Use again in the fall when ants attempt to come inside for the winter.

General Usage Tips for Killing Ants Outdoors

Follow these tips to ensure you effectively kill ants outside.

  • Direct your application to areas that ants and other insects use as common entry points and foraging trails.
  • Spray with caution when wind conditions may create a mist that may blow back to you.
  • Use the attached red extension tube or the spare — when engaged, spray will shoot out a stream 10 to 15 feet long.
  • Look for ant activity around the outside of the house and spray the outdoor surface areas, spraying as many ants as possible.
  • When killing ants outside, do not apply this product in or around bodies of water.


Where to Use

Ants: Use this outdoor ant spray in key areas outside the house, where you suspect ants are entering the structure, such as around downspouts and gutters, near windowsills and door openings. Spray ants directly where possible. Seal up any visible exterior cracks where ants can be seen entering the home. Apply the outside ant killer on ant trails, hills, ant mounds and other areas of entry and infestation.

Carpenter Ants: Carpenter ants usually come from an outside colony and enter your house looking to establish a satellite colony in an area containing water-damaged wood. Carpenter ants are easy to identify because they are larger than all other pest ants. Often you will find them living in wood that has been in contact with water, such as around downspouts and gutters, near windowsills and door openings, close to leaking water pipes, or around decks.

Carpenter ants are most active between dusk and dawn — locate their outside trails during this time. Carpenter ants follow distinct trails such as edges of landscape timbers, along the ground close to outside walls, near downspouts or along the edge of an outside wall. After a careful inspection around the outside of the house, apply TERRO® Outdoor Ant Killer. Outdoor application should include all areas where you suspect ants are entering the home. Seal any visible exterior cracks where ants can be seen entering the home. If ants are discovered inside the home, use a suitable TERRO® indoor ant control product to treat the indoor invasion. If you find the main colony outside in the yard, use the outdoor ant killer spray on the areas where ants are seen entering the main colony.

Spiders: Spray directly on spiders and webs.

Other crawling insects: To control cockroaches, boxelder bugs, crickets, sowbugs and multicolored Asian lady beetles, focus your treatment in key areas outside your house where you suspect these insects are entering. Check downspouts and gutters, near windowsills and door openings. Spray insects directly, where possible, and seal up any visible exterior cracks where crawling insects can be seen entering the home.

Rated 5 out of 5 by from New for me I bought thru Amazon a 2 pk. of the spray for ants out of my reach. I have always used Terro but this product is the best. My problem was ants crawling up the walls and going inside thru the eaves. I used this spray in key areas where entry was observed. In about 3-4 days I had no more ants in vital areas. It worked so well I ordered another pack of 2 just to have when needed. My Home Depot & Lowes carried a lot of Terro products although not the spray. I only use this outdoors and under cover. Just works excellent and I have spent a lot on other products.

Rated 5 out of 5 by from Great products Have used extemators with out much lunch. Started our own defense of the ants. We first use the spray around the foundation . Then the next day we use around the house with positive results . No more ants after a few days. Then we do every four months. Great stuff

Rated 5 out of 5 by from Excellent Product I have tried with( no success )the bait pacts and the bait sticks, the ants just climb over them.....however this foam really works (and it DOES leave an invisible barrier)

Rated 4 out of 5 by from Amazon Review This stuff really works. It gets a lot of liquid in hard to reach places and ants don't ever return. The only drawback is the cans lose pressure. I have some that are almost full but nothing will come out.

Rated 4 out of 5 by from Amazon Review It does its job, and helped get my ant issue under control. I used this in combination with other products.

Rated 4 out of 5 by from Amazon Review To use it, you have to tear off a tab on top of the can. BUT if you use too much force the trigger mechanism comes off and I could not re-install it. So with foam pouring off my hand, I did manage to get some of it on the desired surface. (a mailbox) At the end of that single application, there was nothing left of the can.

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.
