Occasional Invaders

At Peregrine, we offer a variety of pest control removal services for occasional invaders. The common species that invade structures periodically include ground beetles, boxelder bugs, sow bugs, earwigs, centipedes, and black and strawberry-root weevils. Our focus is on removing occasional invaders in a timely and professional manner. The first step with all occasional invaders is to confirm what type of pest is bothering you — once identified, our pest control service technicians will provide you with a solution to meet your needs.

Ground Beetles: are typically found on the ground, usually underneath objects such stones, wood, and other objects in contact with soil. Interestingly, most ground beetle species are nocturnal or active at night. Ground beetles typically enter structures by crawling under doors or entering through open windows. They are considered a nuisance pest.

Boxelder Bugs: Overwintering adults emerge from hibernation, flying back to their host trees in April going through to early May. Like the name suggests the host tree is the boxelder tree. Boxelder Bugs are also found on maple trees. Like a number of different insects boxelder bugs are found  on the south side of trees, bushes, rocks, general lanscaping and other objects. From there, they will move to nearby structures to hibernate for the winter.

Weevils: Black and strawberry-root weevils overwinter in soil, amongst host plants’ roots. Adults emerge from early May to late July. The adults are typically nocturnal. Root weevils enter structures in the fall to overwinter. When outdoor conditions become adverse, they will enter the indoors. This is usually when their food plants die at the end of their season or because of adverse weather conditions.

Sow Bugs: These land-dwelling crustaceans are arthropods, but not insects. They are found worldwide. Sow bugs are found in areas of high moisture because they have high water loss. Their habits are nocturnal in order to reduce water loss. Sow bugs are inactive during the day and remain hidden under objects such stones and wood. They occasionally enter buildings via door thresholds, particularly at ground level. Sow bugs are scavengers and feed on decaying organic matter, usually plant material.

Centipedes: These are sometimes called ‘hundred-leggers’ because of their many pairs of legs. Centipedes are found in areas of high moisture such as loose bark, rotting logs and under stones. Centipedes occasionally invade structures, feeding off flies, spiders, and other dead insects. They are usually found in dark, damp areas of a structure.

Earwigs: The common name of “earwig” comes from an old European superstition where it was thought that these insects enter the ears of sleeping people and bore into the brain.  A great story, but is without foundation. Adults are about 1/4-1″ (5-25 mm) long, with the their body elongate in shape. Earwig colour varies from pale brown with dark markings to uniformly reddish brown to black, but with paler legs.


Ground Beetles: Adults are about 1/16 inches in size, have a long, elongated body, and are somewhat flattened. The colour is usually black and shiny. Some species are patterned and or brightly coloured.

Boxelder Bugs: Adults are about 1/2 inch in size, have an elongated oval shape, and are somewhat flattened. They are black with reddish lines on the topside of their bodies.

Weevils: Adults are about 7/16 inches in size, and their bodies are elongated and oval. The colour varies depending on the species.

Sow Bugs: Adults are about 5/8 inches in size. Their colour is dark to slate gray. They are very identifiable, as they can roll up into a very loose ball when disturbed.

Centipedes: Adults are about 1/8 inch in size. They are elongated, flattened, and worm-like in appearance.

Earwigs: Colour varies from pale brown with dark markings to a uniform reddish brown to black. Adults are about 1/4 inch in size.


The first step with all occasional invaders is to confirm what type of pest is bothering you. Once the insect has been identified, a pest control solution can be provided. For the pest treatment of ground beetles, boxelder bugs, earwigs, sow bugs and black and strawberry-root weevils, an exterior perimeter application is performed on the structure. On occasion, garden beds and surrounding areas are treated. Sealing cracks and crevices on the exterior of the building can take away the opportunity for beetles, boxelder bugs, sow bugs, earwigs and root weevils to enter, and prevent them from overwintering in walls. Speak to your pest control service technician to find out the best solution for your structure!


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

These days, the liquid chemicals used are mainly pyrethrins. These chemicals break down rapidly due to sunlight and because of 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. 1 – 2 mm of rain isn’t an issue. We tend to avoid treating for bugs during rain (mainly because, like us, the pests aren’t out — they are trying to keep dry). The chemical is most effective when the pests are present.

Why do you primarily treat the exterior of my residence for occasional invaders?

The reason that we, at Peregrine, focus on treating the exterior of a structure is because the goal is to eliminate these occasional invaders before they have an opportunity to enter your residence. This is the most efficient and effective approach. On the interior of a structure, we always recommend using a bright flashlight and vacuum cleaner to remove any visible ground beetles, boxelder bugs, or root weevils. Repeat twice (about two weeks apart) and you can expect to remove over 95% of occasional invaders on the interior of the structure.

Why do I get so many bugs in my basement?

During the summer months, bugs make their way through the exterior walls of structures and eventually turn up in basements — particularly basement ceilings where there is warm insulation to nest in and nice dark areas to call home. They overwinter in walls and crawl spaces. Removing clutter and unused items on the exterior of the structure, cutting grass and trimming bushes can reduce the number of hiding spots for a variety of pests, making it harder for them to find the structure. In the summer months, use a sealant to caulk around pipes, gas lines, vents, and other objects at ground level. Every gap that is sealed takes away the opportunity for a bug to find its way inside. Most of all, remember to keep the screen door closed; bugs love to wander in through open doors.

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
Awesome Service!

Will recommend to anyone with pest control problem. They were great to deal with. Jason was awesome and walked us through everything he was doing. Work was done quickly and efficiently and we are so happy the birds are out of our vent!

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

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
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
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
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
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
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
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
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
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!

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!

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.

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.

Happy with the result... Spiders are gone!

The service experience was positive.

Gregg S.Calgary
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.

Craig CarpenterMcKenzie Lake
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
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
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
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

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

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
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
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
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
great Company

Peregrine has been a great company to work with for our needs. Jason, our technician, arrives on time, is very friendly, polite, professional and thorough. Always a good thing to find a company that does a great job, and Peregrine is one of those companies!

Kate C.Calgary

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
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
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
Great Company

I was very happy with their service. Darcy was great

Brent H.Calgary
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.

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!

Taiwo FawumiCalgary
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.

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

It works! We have no spiders.

Sandra L.Calgary
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

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
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
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
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!
