The most common ants found in Southern Alberta are the odorous house ant, pavement ant and carpenter ant. Occasionally, pharaoh ants may show up in multi dwelling buildings. It is important to identify which type of ant is causing problems since the treatment differs depending on the species.

what to
look for

Odorous house ants are among the most difficult to control because they are bait resistant. They are also very adaptable and create numerous sub colonies, nesting beneath ground debris including wood piles, bricks, mulch, loose bark, etc. They may also invade spaces in walls, below carpets, etc. Eliminating odorous ants involves locating each sub-colony and treating it directly and to keep going back until all colonies are gone.

Pavement ants are one of the commonest and trickiest ant pests. They like to set up thousand-strong colonies beneath sidewalks and foundations and may also nest build beneath bricks, stones or compost heaps. You have probably seen these ants foraging food crumbs on your kitchen counter or trailing around in your bathroom. Locating the actual nest of pavement ants can be difficult but this is essential if they are to be eliminated.

Carpenter ants like to colonise wood or underground tunnels and can cause extensive structural damage if left untreated. They have a vicious sting when disturbed so be careful how you approach their nests. You may sometimes see carpenter ants flying from their nests to mate before the females burrow back underground to set up a new colony.

Pharaoh ants are among the most difficult to control. They are commonly found in commercial or institutional buildings where they colonise the spaces behind baseboards or set up home under floor surfaces or at the back of closets. Pharaoh ants are generally introduced to their new nest from contaminated items brought in from outside. Spraying them with insecticide actually makes them worse as the survivors will break off into small groups and find new places to colonize. These ants are best treated by a thorough and persistent baiting program.

for your

For the most part, you can expect to be taken care of while you’re relaxing on the living room couch. Most ant treatments are performed on the exterior of the property. We ask for you to keep off the treated areas until the chemical is dry. If a treatment is required on the interior the first choice will be the use of commercial ant baits. The service technician will provide specific details for your service.
Excellent professional service

I called Peregrine becauce of an ant problem. Since the treatment we have not had any issues with ants so D’Arcy obviously did a thorough job. D’Arcy was professional, patient and easy to talk to. I like the fact there is a 90 day guarantee so if we have any more ant issues I can only assume they will be dealt with in a timely fashion.

Thank you!

I have had ants in my kitchen for three years. I have had 2 other pest control companies in without success. Nick came in and eliminated my problems in two applications. My entire family loves him! Thank you Nick. He is professional, friendly, knowledgeable and effective. I highly recommend Peregrine.

An excellent job

The technician was very helpful and did a thorough job picking up rocks around my pond under which the ants had constructed a massive nest. I have seen no ants since the time of the spraying.
