In the summer months, household flies seem to be everywhere. They are seen inside buildings, around picnic tables, lunch areas, anywhere we gather and there is food. When you sit down at your favourite restaurant, flies invariably make their appearance. Solving fly issues requires knowledgeable, highly-trained pest control service technicians who understand fly habits, breeding sites, and what it takes to eliminate flies. At Peregrine, we have the experience to solve the must stubborn fly issues.

House Flies: suck liquids containing sweet or decaying substances. Larva feed on moist food rich in organic matter. In the summer months they are found outside in garbage, manure, anywhere there is decaying matter. The key to controlling house flies is to remove organic matter, ensure general sanitation is good, and to ensure screen doors are in place to keep all pests out.

Cluster Flies: Cluster Flies typically, as the cool fall days approach, cluster flies gather together on the south and west sides of a building — they often gather close to windows and door frames, preparing to hibernate in gaps on the interior of the structure. On warm winter days, or as spring approaches, the cluster flies emerge and crawl across walls and windows, becoming more active as they warm up. They are attracted to light, so you may find collections of dead cluster flies lying beneath a left-on light bulb in an attic or near a window frame.

Small Flies: prefer a warm, moist environment with plenty of food. Food builds up in cracks and crevices. Many times, food is pushed down floor drains in the process of washing floors. The organic matter builds up over time, creating a perfect breeding ground for small flies. A regular cleaning program is required to take away the food source of small flies. This includes the hard-to-reach areas under counters and equipment. By removing the food source, you break the cycle of the small fly.


House Flies: are 1/4 to 5/16 inch in size, medium to dark grey in colour, the prothorax has four dark stripes, the wing has sharp upward curve of the fourth vain and the calypter is bare with no tuft of hairs present. House flies are prolific breeders and are readily found around livestock and man-made dwellings. It is the most common fly throughout the world.

Cluster flies: are 1/4 to 3/8 inch in size, dark grey in colour, have golden yellow hairs on front part of the thorax, hold their wings flat over their back when resting and have wingtips that overlap. When crushed, they give off an odour of buckwheat honey and they breed outdoors in lawns and fields.

Small Flies: are most commonly species of fruit flies and moth flies. They feed off organic matter. Moth flies are 3/16 inch in size, generally brown to gray or gray-black in colour, with a unique vein pattern on wings, their body and wings are covered with tiny hairs. Fruit flies are 1/8 inch in size, have a tan-coloured head and thorax, have bright red eyes and have no markings on top of the prothorax.


Solving fly issues is hard work and requires persistent effort to be successful — it requires understanding the cause of why flies are present. Additionally, the willingness of the client to change poor behaviour practices is often key to solving fly issues long term. The first part is to identify the species of flies that is the challenge. At Peregrine, we have the right pest control tools and knowledge to solve the most persistent fly issue. Our pest control service technicians prefer to use foaming agents, dusts, commercials vacuums, and fogging agents in combating fly problems. This in conjunction with educating our clients about removing moisture issues, fixing broken pipes, fixing broken floor tiles, sealing gaps or cracks that either hold moisture or organic matter. Remove the fuel and you eliminate your fly issue once and for all.


Why are small fly issues in restaurants reoccurring?

Small fly issues in restaurants are reoccurring for a number of reasons. The main reason is poor sanitation. Areas that are out of sight of the customer are usually the last areas that are cleaned. Very rarely is it just one thing that isn’t cleaned that causes small fly issues. Everything requires maintenance. This means fixing broken floor tiles, cleaning floor drains and cleaning the hard to reach areas. All these areas trap moisture and organic matter. Are the mop heads changed on a regular basis? Or are you just spreading grease every time you mop the floor? Interestingly, even with poor sanitation if you do just one thing you can significantly reduce a small fly problem. Remove the moisture. Warm moist areas equal high fly activity. Remove the moisture and you can solve an active fly problem.

Why are Cluster fly issues reoccurring?

Regrettably cluster flies are a reoccurring nuisance. Cluster flies are one of the few insects where you can only treat the adults. Cluster flies lay their eggs on the soil. Earthworms come along and eat the eggs. The cluster flies then pupate from the earth worm and fly to the nearest structure. This is a cycle that is difficult to break. Cluster flies prefer the south side of a structure. In the early summer, once the flies have left the structure, sealing gaps on the exterior can significantly reduce the potential nesting sites. Entry points include gaps in window frames, doors frames, and any fixture on the exterior of the structure. A multi-prong approach of sealing and chemical applications is required to win the day over an extended period of time.

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

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
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
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.


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
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
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!

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
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!!!

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.

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.

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
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!

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
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

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 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.

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.

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
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

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
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
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
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
Happy with the result... Spiders are gone!

The service experience was positive.

Gregg S.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 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
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
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.

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
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.

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
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
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
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
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
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
