  1. Canadian registration

    Every product here carries a PCP registration number, shown in its specs.

    TERRO outdoor stations and stakes and Ortho granules are for outdoors only. The powders and sprays also have indoor uses on their labels.

  3. Weather

    Safer's says to use its powder outdoors in dry weather. TERRO says its stakes are weatherproof.

  4. Surfaces

    Ortho says to test its granules on a small hidden area first, to check for staining.

Where Should You Use Outdoor Ant Killers?

  • Read and follow the label of every product.
  • Along the foundation, at entry points such as door and window frames, on ant trails and on nests.
  • Put bait stations and stakes where you see ants outside, and keep sprays away from them.
  • Do not use these products on ponds, streams or lakes, as Ortho's listings say.
