Odorous House Ants: Odorous House Ants are among the most challenging of ants to control. Odorous house ants turn up in the most unusual of places. They are very adaptable and create numerous colonies, nesting beneath ground debris including wood piles, bricks, mulch, loose bark, etc. They may also invade spaces in walls, below carpets, and baseboards, etc. Eliminating odorous house ants involves locating each ant colony and treating it directly.

Pavement Ants: are one of the common ant species found. Pavement ants like to set up colonies beneath sidewalks and foundations and may also nest build beneath bricks, stones or compost heaps. You have probably seen these ants foraging for food crumbs on your kitchen counter or trailing around in your bathroom. Locating the actual nest of pavement ants can be difficult but is essential if they are to be eliminated.

Carpenter Ants: like to colonise in wood and can cause extensive structural damage if left untreated. Carpenter ants have a vicious sting when disturbed, so be careful how you approach their nests. Looking for signs of sawdust or moisture problems in walls will lead you to where carpenter ants can be found. Whenever there is wood in contact with soil and there is more than 30% humidity in the wood, you have the potential for carpenter ants to infest the wood.


Odorous House Ants: Ants have one node, one-sized workers about 3.5mm, uneven thoraxes, 12 antennal segments, no clubs, no circle of hair on tip of the abdomen and are brown to black in colour. An easy identification method is that workers give off rotten coconut smell when crushed. The node is flat in shape and is hidden by the abdomen.

Pavement Ants: have two nodes, worker size is about 3mm, uneven shaped thoraxes, 12 antennal segments, antennae clubs with 3 segments, and one pair of spines on the thorax. An easy way to distinguish them is that there are grooves present on the head and thorax. There is also a stinger present at the tip of the abdomen.

Carpenter Ants: have one node, evenly rounded thoraxes, 12 antennal segments, worker size is about 10mm and abdomens have long yellow hairs with a circle of hairs at the tip of the abdomen. They can be identified their distinct single node, black bodies and dark red legs.


Solving ant issues begins by knowing with which species of ants you are dealing. Once you know which species of ants you’re dealing with, you can put together an action plan that will solve the ant infestation. The most common species of ant in Calgary and area is the odorous house ant. It is often confused with the pavement ant. It is only when you put the ant under a microscope that you can analyze the abdomen, thorax, and head, looking for key differentiating features. At Peregrine, we believe the hard work with ants involves finding the nests and exterminating them. In a residential scenario, when exterminating non-wood-boring ants (odorous house ants and pavement ants), we would treat the exterior perimeter of the structure. This will eliminate ants as they are entering and exiting the structure, reducing the need to apply liquid chemicals on the interior. The next step is to inspect and eliminate ant hills and nests in the lawn, garden beds and surrounding areas. Eliminating the nests takes the pressure off the structure and will provide long-term results. On the interior, commercial gel baits are typically used. Wood-boring ants, such as carpenter ants, require a similar approach. The big difference is that many times there are carpenter ant colonies far within the walls of a structure — they require the help of a pest control professional to effect extermination.


How do I know if I have carpenter ants?

In Calgary, most Carpenter ant work is fortunately quite minor. A typical scenario would be for carpenter ants to have made a colony in an exterior window frame. On acreages outside of Calgary, carpenter ant jobs seem to be more severe; they can inhabit multiple walls in the structure and are often found in the exterior surrounding areas. The best way to identify a carpenter ant is by scooping a few up and placing them in an old plastic container for your pest control service technician to inspect. If you see piles of saw dust in the middle of a room, falling out of a baseboard or window frame, you may have carpenter ants. You need to have 30% humidity in the wood for carpenter ants to make galleries. Does the structure have water issues? If it does, you have a potential problem.

We stand behind all our work. Should any problems arise within 90 days of the job, we will return for no extra charge, completely hassle-free.

It rained last night. Will this wash away the chemical?

The liquid chemicals used today are mainly pyrethrins. They break down rapidly due to sunlight and mechanical actions such as vacuuming, mopping and sweeping. Depending on the brand of chemical and how it was applied you can expect the chemical to last around 30 days on the interior and up to 14 days on the exterior of the structure. One or two millimeters of rain isn’t an issue. We tend to avoid treating for ants during rain, mainly because, like us, the ants aren’t out — they’re trying to keep dry. The chemical is most effective when the ants are present.

Do ant baits work?

The short answer is yes — ant baits work, but they require a lot of patience. Ants are very fussy eaters. In the morning, the colony may want protein; in the afternoon, the ant colony may want carbohydrates. Understanding this means putting out 2 or 3 different kinds of ant baits to appeal to the colony at all times. Most ant baits come in a 5% concentration, but this strength is too high. The ants usually die before they make it back to the nest. An ideal concentration is between 1% – 3%. Yes, ant baits do work, but they have limitations and results are not instantaneous.

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.

Henry is the Best!

We have used other pest control companies, but Henry from Peregrine went above and beyond our expectations. He worked hard to find the point of entry and made certain it was blocked. Henry was professional, thorough and provided excellent advice. In our opinion, Henry and Peregrine are the best pest control
experts in Calgary.

Excellent Services

Services are superb..! I recommend them.

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.
