TERRO® is committed to supplying homeowners, property owners and commercial customers with the insect control solutions they need to get back peace of mind.


“It Works™!” That’s what people have been saying since introducing TERRO® Liquid Ant Killer in 1915. It began as one of the earliest products created for liquid ant baiting, and remains the gold standard. Today, four generations of consumers have come to know that the brand in the bright orange package stands for “Ant Control”. .

Since our early beginnings, the company has now grown to offer a variety of proven ant and pest control solutions, including liquid ant baits, perimeter products and pest insect traps. TERRO® continuously strives to manufacture quality products targeted to meet the varying needs of you, the consumer! Whether you are attempting to fight an ant invasion or prevent insects from entering your home, there is a solution to fit every situation.

TERRO® is one of several brand names offered by Woodstream Corp., which has had a presence in Canada since the mid-1800s. We got our start in Canada by selling our game traps to the Hudson Bay Company over 150 years ago, and we have been enjoying a strong relationship with our distributor and retail friends ever since.

In 2013, TERRO® insect control products were introduced to Canada, offering the same great consumer satisfaction as we have since the very beginning. Now, our products are available in many retailers across the country, including Canadian Tire, Home Depot, Home Hardware and more. At TERRO®, we have an ongoing commitment to offer consumers the right product when they need it. It is with that commitment that we continue to work on expanding our presence in Canada.

Liquid Ant Baits

Q: How do TERRO® Liquid Ant Baits work to control ant invasions?

A: As the ants forage for food, the sweet liquid in TERRO® Liquid Ant Baits lures the ants. They consume the bait and return to the colony to share with the other ants. While the active ingredient in the bait will ultimately kill the worker ant, it works slowly enough to allow time for foraging ants to make several trips to the bait and deliver it back to the rest of the unsuspecting colony. Within a few days, you should see a significant decrease in the number of ants visiting the bait.

Q: How do I clean TERRO® Liquid Ant Bait that has spilled out of the bait station?

A: If you’ve spilled the bait inside your TERRO® Liquid Ant Bait station, don’t worry. Cleaning up spilled ant bait is easy, even if it gels or solidifies after exposure to the air. Here is what you need to do:

  • Wet a sponge or cloth with hot water.
  • Place the wet sponge on top of the spilled ant bait.
  • Leave the sponge in place for about an hour.
  • After an hour, wipe the affected area clean.

Q: Why do my TERRO® Liquid Ant Bait stations seem to be attracting more ants?

A: There’s nothing to worry about – this is actually a good sign! Initially, you will see more ants as foragers looking for food discover the sweet liquid inside the station and carry it back to the colony. On the way back to the colony, ants leave a pheromone trail to let others know where the food is. These other ants, in turn, follow the trail to the bait, which explains why you initially see more ants.

The active ingredient in the bait eventually kills ants within 24-48 hours after consumption. This slow kill gives the worker ants enough time to make multiple trips to the bait and share it with the rest of the colony. Baiting is the only way to successfully wipe out the ants you see and the ants you don’t.

Insect Traps

Q: How do TERRO® Fruit Fly Traps work to control fruit fly invasions?

A: All stages of a fruit fly infestation depend on moist organic debris to complete the fruit fly life cycle. The non-toxic, food-based liquid in the TERRO® Fruit Fly Trap lures adult flies into the traps. Once the flies enter the trap, they cannot escape to continue breeding and multiplying.

Q: Why aren’t insects flying around my house attracted to the TERRO® Fruit Fly Trap?

A: Gnats, drain flies and other types of nuisance flies are often mistaken for fruit flies. As their name suggests, fruit flies are attracted to fruit, while other insects may not be. You can usually find small, winged fruit flies hovering near ripe produce, garbage cans and open wine bottles. To determine what type of infestation you’re dealing with, place a TERRO® Fruit Fly Trap near the area where insects are swarming. If the flies aren’t attracted to the lure, you probably aren’t dealing with a fruit fly invasion.

Q: How do TERRO® Pantry Moth Traps work to get rid of moth invasions?

A: Pantry moths are attracted to products such as whole grains, flour, cereal and dry pet food that are commonly stored in kitchen pantries. Each TERRO® Pantry Moth Trap includes glue traps and individually wrapped lures. These lure pellets contain a powerful pheromone that attracts pantry moths into the trap where they get stuck to the sticky surface and eventually die. When placed in areas where you observe moths swarming, these traps can effectively target an infestation. For best results, replace the traps every 3 months or sooner if they become dusty or full.
