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.


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 12 months 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.

Great Company

I was very happy with their service. Darcy was great

Brent H.Calgary
Friendly and knowledgeabe

Had a very friendly and knowledgable technician visit to help with our gopher problem. The applications seems to have worked quite well after watching population diminish greatly within a week or so. Also super friendly telephone service while booking, and follow up call was also appreciated. Peregrine (Charles) was out a day after I called…Would definitely recommend.

Ryan McGrathCalgary
Very satisfied with the outcome

I had one of the worst wasp tree infestations and a wasp nest under my step. With one visit Peregrine has fixed the problem and no more wasps. Very professional and quick to respond

Colleen R.Calgary
We are so happy with the friendly and effective next day service we received

Peregrine was fast, friendly and very effective at completely removing the spider infestation at our house, around our deck and even in our rock gardens. The technician was very friendly and it only took a couple hours before it was safe for the dogs to go back outside. We’ll be using their services again in the future.

Kerri P.Calgary
Far and away the best

As a facility manager at a private school I have used most every pest control company in Calgary at least once. Peregrine is far and away the best. They have attentive service and seem to actually care about what is occurring in your situation. Unlike some of the bigger companies who only come if they feel like it and do the bare minimum to keep your contract. You won’t get any of that from them.

Jeremy KeysCalgary
Thanks for the great job!

We installed solar panels on our roof and found that it did not take long for pigeons to be attracted to the roof. We had not had a problem previously so it was related to the solar panels. We had Peregrine look at the panels and make recommendations. We decided to have a barrier installed along the edge of the panels. This was done efficiently and per the quote. The barriers are like the spikes installed under bridges to prevent birds from roosting on beams and supports. The barriers have eliminated the problem with birds. Thanks for the great job!

Randal HarrisCalgary
No spiders since you sprayed. It has only been a few weeks though.

I can’t say the service has worked yet. I was reassured if the spiders do return within 90 days that you will re spray so I do rate that high. The fellow that came out was very polite and answered all my questions.

Quick Service

Booked an appointment within two days for vole control. Traps were placed and the problem was resolved right away. Very friendly service from all involved.

James G.Calgary
A load off my shoulders

Had a nasty case of bed bugs and thankfully found Peregrine Pest Control. The receptionist who answered the phone was polite and helpful and I immediately felt like a load was off my shoulders. They told me everything I needed to do to prepare for the visit.

The guy who came to take care of the problem was professional and efficient. I would recommend them to anyone and everyone!

Aaron BartholomewCalgary
Fantastic service!

Nick with Peregrine Pest Control is a very professional man who knows his mice! He was quick to contact me when I first put in my cry for help and has been very organized and punctual with maintenance and return visits. I would, and have, recommended Peregrine to friends and family.

Happy Customer

Called Peregrine Pest Control regarding a gopher issue, and was so impressed with their service that I then hired them for my ant problem, a problem I had tried, unsuccessfully, to deal with myself over the years. Their work is very thorough and since the spraying (2 months ago) my yard is still ant-free (and gopher-free 🙂 ). I honestly didn’t think that could be possible. I definitely would use their service again – if needed.

Happy CustomerCalgary
Very thorough

Very thorough removing a large, underground and hidden bumble bee nest. Even took the time to remove the remains of a dead wasp nest that I was way too scared to touch! Would recommend.

Zorana VCalgary
Quick response, friendly and efficient

Darcy walked me through the procedures he would be using to take care of a concealed wasp nest and performed the work quickly and efficiently. Has been close to one month with no problems. Very pleased with the service provided.

Sam K.Calgary
Went the extra mile

Thanks to the team at Peregrine for their great service – we fixed our squirrel problem in a matter of days. Went the extra mile for us and was incredibly helpful, knowledgeable and professional.

I’d highly recommend this company to anyone and will definitely use them again if I ever need to.

Amy WallnerCalgary
2 skunks caught within 12 hours!

Nick did a great job preparing me for what to expect and to be patient with the results…but I didn’t have to be! Within 2 hours both skunks were in the traps and gone!

Rosanna T.Calgary
Happy with the result... Spiders are gone!

The service experience was positive.

Gregg S.Calgary

They were friendly and helpful (even dealing with a nervous nelly like me). I think there were about 15 e-mails over the 2 days trying to help me calm down about what was going on. They never got snarky or made me feel stupid for asking questions.

Kelly F.Calgary
Fantastic response time, professional and helpful.

We were on holidays only to come home to a skunk who had been hibernating under our patio. I contacted Nick with Peregrine pest control and within hours (on a statutory holiday) he contacted us back. He gave us the pricing over the phone and made arrangements so we could be home to learn to set the traps. Within 8 hours we caught a HUGE skunk in the trap. He picked it up immediately and dispersed of it. Thank you!!

Lisa D.Calgary
Very helpful

Nick was very helpful in helping us get rid of our squirrel problem. I have used other exterminators for this problem and never had any success. The traps worked great and now, touch wood, we are squirrel free for the first time in years!

Liz L.Calgary
Friendly, helpful and knowledgeable

I found Peregrine staff, both office and field very friendly, helpful and knowledgeable. They make sure their work is completed properly and care to call you back to ensure that your problems are taken care properly.

Luis N.Calgary
Wasps were gone within a day of spraying.

The job done was effective in dealing with the underground nest. No sign of wasps after a day had passed. Service arrived on time and was courteous and helpful when questions were asked.

Alain L.Calgary

Huge thank you to Marilyn who answered my panicked phone call regarding sqiuirels and bugs. Marilyn was very empathetic and a much needed calming force for me. She was very professional and able to ensure Nick came the next day to help resolve my “issues”.

Jill B.Calgary
Bed bugs from China!!

Both Darcy and Marilyn at Peregrine were knowledgable and efficient. Thanks for the help.

We were so inundated with spiders last year you had to always clean the deck before you used it. To date I have seen two very tiny spiders and that is all. It was well worth the price.

M Sylvia D.Calgary
Quick service and follow through, ridding my acreage of pocket gophers.

Peregrine General Pest Control has been keeping my place as pocket-gopher free as possible.
They are courteous, quick to respond to your needs, and thorough.
I would heartily recommend them.

Frances H.Calgary
Very efficient, professional, and good workmanship.

Peregrine General Pest Control was referred to us by someone who had used their service for a problem with mice. We hired them to deal with pigeons at a condo complex with 18 units, and they did the job well. Also, their price was half of what we got from another company.
Nick responded to us very quickly and had the work done in a timely manner. The roof of the condominium is very steep, so it required quite an effort to even climb up there. Nick told us to call him right away if there were any problems down the road, and he would take care of it.
We have had no sightings of pigeons or droppings since the job was completed. I would highly recommend Peregrine General Pest Control.

Efficient, professional, respectful

The customer care representative did a thorough search of our home, inside and out, set safe traps in strategic locations, and explained the process clearly to me. They’ll return in 30 days, and then again in another 60 to make sure our house remains pest free. Peregrine were recommended to me, and I wholeheartedly recommend them to anyone dealing with mice in your home.

Rachel S.Calgary

It works! We have no spiders.

Sandra L.Calgary
First, it was mice...then wasps...now many bird nests!!

This is the 3rd time we’ve been able to use Peregrin Pest Control and have recommended them to others. Always great service, thorough follow up and communication. A pleasure to deal with, to be sure. You will not regret booking Peregrin!

Marquis De Lorne Community AssociationCalgary
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.

Jill RodriguesCalgary
Unwanted mouse (...or mice??)

Once we noticed there was a mouse (mice?) problem, we had the owner out the very next day to set the traps and walk our house with us. He reviewed everything we needed to know in detail. Will be getting our 30 day follow-up later this month to confirm that the problem has been removed. Currently on day 2 of no droppings – here’s keeping our fingers crossed.

Nick was very professional and explained what he was going to do

Prompt and courteous service. Effective results and though inspection of the property

Richard T.Calgary
Huge help

Had voles last year and a pocket gopher that moved in due to expanding suburbia. Called many for quotes but Marilyn was the first and only one to take the time to help me figure out what the problem really was and how to deal with it. Chuck came out and helped me understand how the critters live and how to prevent their return… Huge help as i was stressed about my plants,kids and using traps around kids. in case next year my garden looks better than the mud hill behind me, I will call them again if I have problems but I’m sure that with such thorough work from chuck, we will be fine. Thanks guys!

Lori R.Calgary
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.

Heather C.Calgary
Service with a smile!!

Nick and his team are great!! We have used the “other guys” for years in our restaurant. Had a problem at home so I phoned Nick and had to use his team at our business after that! Nick does a great job with the basics then always goes obove and beyond suggesting and educating us with ways to help keep our restaurant clean and safe from pests!! Thanks Nick!!!

Dennon M.Calgary
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.

Donna K.Calgary

Very professional and thorough. Nick took the time to respond to all of our questions and educated us about the issue. Most importantly, Problem is now resolved! Top notch!

Selina K.Calgary
Excellent Service and Results

These guys were great! Took care of our skunk problem quickly and efficiently. All the staff was very friendly.
Recommend them to anyone!

Dinah C.Calgary

So far, service has been exceptional. They have set multiple traps for the pocket gophers that decided to make our yard their next home. Service is prompt, reliable and friendly. They take the time to explain things to you which appears to be rare these days. I highly recommend them.

Christy NelsonCalgary
Ken was very professional and extremely friendly. Our roach problem is now solved!

I had the pleasure of having Ken at our home to help with our roach problem. Ken was very professional and extremely friendly. He took time to explain what he was doing and why. We had a good chat about other topics as he does his thing. It was really nice to meet Ken – he has such a wonderful personality.
Our roach problem is also now solved. Thanks Ken!
