Start by checking if the business is licensed by Alberta Health Services and carries proper liability insurance. It sounds basic, but you’d be surprised how often that gets overlooked. Without those in place, you’re potentially opening your home to unqualified technicians using products that may not be safe–or even legal. Insurance also matters more than most people think. If something goes sideways, you’re not left cleaning up the mess.
Ask directly about the types of treatments used and whether they include follow-up visits. For example, some Calgary firms offer one-time spray options, while others include recurring check-ins over several weeks. I once assumed a single visit was enough to deal with ants in my basement–it wasn’t. Turns out, without return inspections, new nests kept forming behind the drywall. An ongoing plan would’ve caught that faster.
Read through customer reviews with a bit of scepticism. Not all five-star ratings reflect long-term results. Look for feedback mentioning timelines, technician communication, and whether the problem stayed gone. Also, dig into how the service handles complaints. A company that calls back promptly, sends a tech out again if needed, and doesn’t nickel-and-dime for re-treatments? That’s worth bookmarking. One Calgary outfit we looked at even posted clarity on where their sprays go, which I appreciated because no one wants chemicals near winter coats.
Lastly, if someone offers a quote without asking a single question about your home, that’s a red flag. Any reputable specialist should ask about square footage, type of issue, where it’s occurring, and even previous treatments. It’s not just being thorough–it’s being accountable.
How to Choose the Best Pest Control Company

Start with licensing. If they can’t provide a valid Alberta service license, walk away. Proper certification isn’t just red tape – it’s proof they meet minimum provincial standards. Some contractors might sound convincing over the phone, but unless they’re certified and insured, you’re taking a gamble.
Next – treatment plans. If someone gives you a quote without even asking what kind of issue you’re dealing with, that’s a red flag. Real professionals will ask questions. What’s the target species? Is it seasonal or persistent? They’ll explain whether baiting, exclusion, or targeted application makes more sense for your property. If you’re specifically dealing with insects in your plumbing, ask directly whether they can handle drain flies. Not everyone can. Or will.
Then there’s warranty. A lot of companies offer guarantees that sound impressive but read the fine print. Does it include follow-ups? Are reapplications covered? Is it just for 30 days? Some services fall under property maintenance – but if you’re relying on third-party protection, confirm whether a home warranty covers infestations. Don’t assume it does. You might find out too late it doesn’t apply in Calgary.
Finally, ask who’s doing the work. Not just which company – who exactly. A franchise might send a rotating crew, while a local technician will remember your attic layout, your crawlspace access, or that stubborn wasp nest from last summer. That kind of memory – that consistency – makes a real difference. Especially when timing matters and you don’t want to explain the whole situation again.
What licenses, insurance, and certifications a pest removal provider must have

Always ask for a provincial license. In Alberta, anyone applying chemical treatments must hold a valid Pesticide Applicator Certificate issued by Alberta Environment and Parks. If they don’t have that, walk away–no exceptions. This license confirms they’ve completed proper training and passed the government’s exam. It’s not just paperwork; it’s proof they understand safe handling, application methods, and emergency procedures.
Check that they carry active liability insurance. It should cover property damage and personal injury–ideally a $1M policy or higher. Accidents during fumigation or misapplication of chemicals are rare, but if something does go wrong, you don’t want to be left responsible. Some smaller outfits skip this step to save money. That’s a red flag.
Certification through industry bodies like QualityPro or the Canadian Pest Management Association (CPMA) can indicate a higher standard, though not mandatory. These programs often require background checks, continuing education, and written service protocols. Personally, I don’t think a lack of these makes someone unreliable–but when everything else checks out, it’s a solid bonus.
What most people forget to ask about
Worker’s compensation coverage. If their technician gets injured on your property and they’re not covered by WCB Alberta, you could be held liable. Few homeowners think about this. Ask directly: “Are your staff covered by WCB?” You’ll learn a lot from how they answer.

Compare treatment methods and safety practices before booking
Ask what specific solutions are being used–not just the product name, but also its active ingredients. Then, check if those substances are approved by Health Canada’s Pest Management Regulatory Agency (PMRA). If they aren’t, or if the technician avoids direct answers, that’s not a good sign.
Eco-friendly doesn’t always mean safe. Some companies market “green” treatments, but those can still trigger allergies or require vacating your home for several hours. Others may suggest integrated approaches like physical exclusion or traps, which can be safer–but might take longer to show results. Depending on your situation, that could be fine. Or frustrating.
Ask whether indoor and outdoor areas will be treated differently. A good technician should explain if bait stations will be used instead of sprays inside, especially if there are pets or kids in the home. If the same chemicals are used everywhere without adjusting for exposure risk–that’s a red flag.
Ask these before agreeing to service:
- Do they offer a written explanation of all products used?
- Will the technician walk through safety protocols onsite?
- Is there a re-entry wait time? How long is it, and why?
- Do they provide MSDS (Material Safety Data Sheets) on request?
- Are non-chemical options available for sensitive areas?
Also, don’t assume “licensed” means “safe.” It just means the provider passed regulatory requirements. Real safety comes down to clear communication and method selection tailored to your space. A reliable technician won’t pressure you–they’ll offer options and let you decide based on your comfort level and risk tolerance.

What to Ask About Guarantees, Contracts, and Follow-Up Services
Before signing anything, ask directly what happens if the treatment doesn’t work. Is there a free re-service window? Some providers offer 30-day guarantees, others longer–but the details vary. Don’t assume anything is included unless it’s in writing.
It’s also smart to ask about ongoing support. For example, if you’re dealing with mice and need more than one visit, will they monitor the situation or just leave traps and disappear? Good services usually schedule a follow-up within a set time, especially for infestations that don’t clear up right away. If you’re unsure when to involve specialists, here’s a good reference: when to call pest control for mice.
Key Questions to Ask
Topic | What to Ask |
---|---|
Guarantees | “If the issue returns in a week or two, is there a no-cost retreatment?” |
Service Agreements | “Is this a one-time service, or does it require a contract?” |
Contract Terms | “Can I cancel the agreement if results don’t meet expectations?” |
Follow-Up | “Will someone come back to inspect or check on progress?” |
Red Flags to Watch
If someone avoids giving clear answers or insists on a long-term contract without flexibility, that’s a sign to keep looking. Same goes for vague guarantees like “satisfaction guaranteed”–what does that actually mean?
Also, be wary of pushy upsells. If every solution seems to require a multi-year plan, ask why. Sometimes it’s necessary–especially with difficult infestations–but not always. You want someone who can explain the reasons, not just sell the package.
Q&A:
How can I verify if a pest control company is properly licensed and insured?
Ask for the company’s license number and check it against your province or municipality’s online registry. For example, in Ontario, you can search the Ministry of the Environment’s pesticide licensing database. Also, request proof of liability insurance and workers’ compensation coverage. A reliable provider won’t hesitate to provide this documentation.
Is it better to choose a local pest control service or a national chain?
Local companies often offer more personalized service and have a deeper understanding of regional pest activity and seasonal trends. However, national chains may have access to broader resources and standardized procedures. Compare customer reviews, service flexibility, and pricing transparency before making a decision.
What should I expect during the initial inspection?
The technician should examine both the interior and exterior of your property, looking for entry points, nesting areas, and signs of pest activity like droppings or damage. They should also ask about any recent sightings or issues you’ve experienced. After the inspection, you should receive a written assessment and recommended treatment plan.
Can I stay at home during pest control treatment?
It depends on the type of treatment used. For non-toxic methods or bait traps, staying home is usually fine. However, if chemical sprays or fumigation are involved, you may need to vacate for several hours or longer. Always ask for written instructions specific to the treatment method.
Do pest control companies offer guarantees?
Some companies offer a satisfaction guarantee or a service warranty, usually ranging from 30 days to several months. This means they will return for free if pests reappear within the warranty period. Ask what’s included in the guarantee, and make sure the terms are clearly written in your service contract.
