How to Control Ants Outside Your Home

Ants can establish nests outside the home, and this may lead to garden and crop damage. But foraging ants may enter your home, looking for food and water. Once they find a way inside, some ants can even establish nests inside walls, cabinets, behind refrigerators, stoves, ovens and other appliances, behind windows and window frames, and beneath floors. The best way to prevent this is to exterminate the ants outside before they enter your home.

Some ant species even present a health hazard to humans and animals. Stinging ants such as Fire Ants may present a medical problem to individuals who are allergic to their stings. To eradicate a stinging ant population, it is vital that you find the nests. Nests may be in the ground, but also may be hidden under stones or sidewalks.

Controlling Ants on Outside Perimeter with Non-Repellent Insecticides

The best insecticides for ant control as a perimeter treatment are non- repellent insecticides such as Taurus SC, Fuse Insecticide, Termidor SC, Spectre 2 SC

Ants cannot detect the presence of non-repellent insecticides; since they cannot avoid it they quickly make contact. Repellent insecticides will simply scatter the ants and stress the colony. Once an ant colony is stressed, the ants scatter and recolonize in other locations. Once this occurs, you will have more ant colonies to exterminate.

Unlike older insecticides, non-repellent insecticides can't be smelled, tasted, or even felt by pests. They crawl through the treated area, and ingesting treated materials or merely contacting the residual insecticide results in their eventual death.

Note: Taurus SC, FUSE Insecticide, Termidor SC, are labeled for outdoor use only. Spectre 2 SC may be used inside and outside.


Controlling Ants that Enter from the Outside

Many times ants that live outside will find their way inside and become a major nuisance. These ants may not be simply foraging for food and going back outside. They may be seeking a hiding or nesting site.

Ant control bait treatments and/or non-repellent residual insecticides can be used to control ants in both outside and inside.

Steps To Prevent Ants From Entering Your Home

  1. Caulk and seal cracks and crevices to eliminate passages into the home. You may not be able to seal all the entry points as ants are incredibly industrious in finding entry points.
  2. Clean around entry points with a detergent to remove the pheromone chemical trail.
  3. Spray a non-repellent residual insecticide such as Taurus SC, Fuse Insecticide, Termidor SC, Spectre 2 SC around the perimeter and entry points. This method is probably the most successful method to easily and quickly get rid of ants.
  4. Place ant baits around ant activity. If you choose to bait, set the bait in areas of ant activity or trails so the ants can find the bait and take it back to their colony. Do not to use a repellent residual insecticide in the same areas that have bait placements.When baits are placed, the worker ants eat the bait, take it back to the nest, and feed it to the queen and larval Ants. This type of control is incompatible with repellent spray treatments that prevent workers from returning to the nest with the bait.
    • Use both sweet-based bait and a greasy/protein-based bait combination in order to make sure that the bait choice will cover the entire range of Ant dietary needs.
    • Click: Summary review of Ant baits for all ant baits.
    • It may take a couple of weeks for baiting to work. When the ants eat up their baits, replace it with more baits. When you see the baits disappearing, you know it is working, so just be patient!


Taurus SC

Taurus SC

Taurus SC is an excellent non-repellent insecticide for ants and termites. For ant control, it is sprayed around the house 18 inches out and 18 inches up the outside of your house, as a perimeter treatment. Clean up any vegetation, so ants will not be able to bypass the treatment.


FUSE Insecticide

FUSE Insecticide has a combination of two different non-repellents for an effective perimeter treatment for ant control. FUSE has an added advantage of flexible treament options according to dilution concentration and timings of applications.

spectre ps

Spectre PS Aerosol

Spectre PS Aerosol is a non-repellent aerosol that comes with a crack and crevice tip to spray in cracks and crevices.

Spectre 2 SC

Spectre 2 SC, with Chlorfenpyr 21.45%, may be compared to the popular non-repellent Phantom Insecticide, but more economical. As a non-repellent insecticide, Spectre 2 SC is not detectable to the insects (so the insects do not avoid it)


Ants In The Yard

The preferred non-repellent insecticides mentioned above are only labeled for perimeter or treatment of ant trails, so cannot be used as a broadcast application. Broadcast applications should be done with Bifen It Insecticide or Bifen LP. The Bifen LP Granules will last three months. Bifen IT will last about a month. Bifen It is more versatile, and can be used for a variety of outside insects such as Fleas, Ticks and Mosquitoes.
