Expect to set aside 30 to 90 minutes for a standard visit. That’s the average window technicians usually need when working through a typical residential space. Apartments or smaller homes tend to fall closer to the lower end, while multi-level houses, basements, and garages add more time.
Of course, it depends. A quick perimeter barrier along the baseboards might only take half an hour. But something more involved–like addressing an interior ant issue or inspecting attic access points–can stretch the appointment quite a bit. I had a townhouse once where a thorough job took just under two hours, mostly because the technician was being extra careful around a baby’s room. Didn’t mind.
If exterior work is included, that usually adds another 15–30 minutes. Spraying around foundation walls, doors, window frames, and decks takes a bit more effort than you’d think, especially if access is tricky or there’s heavy vegetation. One tech mentioned it can take longer after rain, since reapplication in certain spots may be needed.
Prepping beforehand makes a difference. Moving furniture away from walls or clearing kitchen cabinets in advance can shave off 10 to 20 minutes easily. On the flip side, if the team has to move everything themselves, you’ll be there longer. It’s not a dealbreaker–just something to keep in mind.
One last thing: follow-up visits are shorter. These often run about 20 to 40 minutes unless the situation has changed or something unexpected pops up. Most people find the second visit feels quicker, probably because they’re less anxious than the first time around.
Average Duration for Spraying a Standard-Sized Home
Expect around 20 to 40 minutes for a typical three-bedroom house. That’s assuming standard access and no unusual infestation. A smaller bungalow might wrap up in 15 minutes. Larger two-storey homes could stretch closer to an hour, especially if you’re including the garage, basement, or yard.
Interior work alone often goes quicker–especially if furniture is already pulled back from baseboards and there’s a clear path. Exterior treatment usually adds 10–15 minutes, depending on yard layout and how many cracks or vents need attention. No two houses are quite the same, though. Corner lots, for example, tend to take longer due to exposure on more sides.

Some techs move fast, but don’t rush them–rushing usually means missing something. I’ve seen places where the technician finished too quickly, only to get called back a week later. Better to let them take their time and do it right the first go.
Also worth noting: if the service includes attic dusting or wall voids, add another 10 to 20 minutes. These aren’t part of every visit, but when needed, they do add a bit of time.
Time Required for Interior vs. Exterior Pest Treatments
Plan for about 20 to 30 minutes inside a standard-sized home, assuming access is clear and rooms aren’t cluttered. Kitchens, bathrooms, basements–these take the most attention. If you have pets, factor in extra time for setup and safety precautions.
Outside work moves faster. Most exterior applications around a detached house take 15 to 20 minutes, sometimes even less. Unless there are complex areas like garden beds close to the foundation or decks with limited clearance, it’s mostly perimeter work–windows, doorways, vents, that kind of thing.
Combined Service Times
If you’re booking both indoor and outdoor coverage at once, expect the whole visit to run 40 to 60 minutes. Maybe more if the technician has to move furniture, explain steps, or deal with entry restrictions–like locked gates or tenants not home. That stuff slows everything down.
One more thing–weather plays a role. Wet conditions delay exterior work, sometimes even cancel it. But indoor work goes ahead either way. So timing can shift based on the day. There’s no fixed script.
What to Expect During Commercial Property Servicing
Block out at least 2 to 4 hours. For larger buildings, or ones with multiple levels and units, you might need a full day. Multi-tenant properties with shared spaces–hallways, lobbies, mechanical rooms–tend to take longer. Not just because of size, but due to access issues and coordination with property managers or security.
Preparation speeds things up. If furniture is moved away from walls, access panels are open, and tenants have been notified, the technician can move faster–maybe cut down an hour or more. Without that, expect delays. Sometimes it’s not even the treatment itself that takes time–it’s waiting to get into locked offices or navigating cluttered storage areas.
Warehouses or industrial units? Usually quicker than offices. Less furniture, fewer tight corners. Still, if there’s inventory that needs to be covered or moved, that adds time. Food-related businesses or facilities with strict hygiene rules also stretch things out. Protocols slow the process, but there’s no workaround there.
In Calgary, heating systems or seasonal factors might affect timing too. For example, during colder months, exterior applications might be paused or rescheduled. That can break up what would’ve been a single visit into two shorter ones.
Some techs move faster than others, and not every property is set up the same. So while there’s an average, it’s better to ask during booking. Mention the layout, square footage, and any unusual site conditions. That’ll give a clearer idea than any general estimate.
Duration Differences Based on Pest Type (Ants, Roaches, Termites)
Plan at least 20 to 30 minutes for a standard indoor treatment targeting ants–unless the infestation is spread across multiple floors or hidden behind structural elements. In those cases, a follow-up visit might be needed within 7 to 10 days. Ants tend to follow trails, so most of the focus is perimeter-based, which makes it quicker than more invasive types.
Roach situations are usually more involved. If it’s a light presence, say a few in the kitchen or bathroom, it might still take 30 to 45 minutes. But if there are signs of a colony–egg casings, droppings behind appliances–expect the session to stretch past an hour. Technicians often have to pull out appliances, drill access holes, or apply gels and dusts in multiple stages. And because roaches are nocturnal, extra time is needed to catch signs that aren’t immediately visible.
Now, termites are a different story altogether. It’s not a quick in-and-out visit. A proper subterranean termite application often runs several hours–sometimes half a day or more–depending on square footage. The technician may have to dig trenches, drill through concrete slabs, or inject product deep into wood. Drywood termites? That’s even trickier. If the infestation is isolated to a window frame, maybe 60 to 90 minutes. But if it’s widespread, it could require full structure treatment or even fumigation, which is a multi-day process, not just a timed appointment.
Quick Breakdown:
- Ants: ~20–30 minutes per unit; minimal disruption unless the nest is concealed.
- Roaches: 30 minutes to 1+ hour, depending on how deep they’ve settled in.
- Termites: Several hours to multiple days, depending on species and severity.
One more thing–
Revisits are common with all three, but especially with roaches and termites. You might not see immediate changes. That’s expected. Don’t assume it didn’t work just because activity continues the next day. In most cases, you’ll notice a clear decline after 72 hours, with follow-ups scheduled based on monitoring, not just a timer.
Factors That Influence the Spraying Time
Expect a technician to spend more time on larger properties, especially ones with complex layouts or multiple structures. A 3-bedroom home with a finished basement and attached garage? Easily double the time of a compact condo. And if there’s a backyard shed or detached suite, that adds another layer of work.
Size and Access Matter
- Small apartments: Usually under 30 minutes, unless access is restricted or the infestation is hidden.
- Average suburban homes: Plan for 45 minutes to an hour. Add time for crawlspaces, attics, or cluttered basements.
- Commercial spaces: Depends heavily on layout–open offices go faster than restaurants with storage rooms and prep areas.
Type and Severity of Infestation
Light prevention or maintenance visits don’t take long. But if you’re dealing with a heavy bed bug situation, or carpenter ants tunnelling through the walls, that’s not a quick job. The technician might need to move furniture, open up access panels, or return for multiple passes. For something like German cockroaches, especially in kitchen settings, even an hour might not be enough.
- Mild activity: 20–30 minutes, often a surface-level treatment.
- Moderate to severe: 60–90 minutes, possibly more depending on how cooperative the space is.
And then there’s product type. Some require precise application, like gel baits or spot treatments. Others, like broad-spectrum mists, cover ground faster. Weather also plays a role–outdoor treatments might need to be postponed or rushed if rain is on the way. Wind matters too.
Lastly, the technician’s approach counts. Some are fast and focused. Others take time to explain everything, double-check, or go over areas twice. Neither is wrong–it just shifts the clock a bit.
How Long You Need to Stay Out After Spraying
Typically, vacating the treated area for at least 4 to 6 hours is recommended to reduce exposure to chemicals. This timeframe can vary depending on the formula used and the type of infestation addressed. Some treatments may require staying away for up to 24 hours, especially if heavy residuals or fogging methods are involved.
For liquid applications, a minimum of 4 hours usually allows surfaces to dry and vapours to dissipate. Powder or bait treatments often need less time, sometimes just an hour or two, since these pose lower airborne risk but still call for caution.
Factors Influencing Re-Entry Time
| Application Type | Typical Waiting Period | Reason |
|---|---|---|
| Liquid sprays | 4 to 6 hours | Surface drying and vapour reduction |
| Fogging or misting | 6 to 24 hours | Airborne particles linger longer |
| Bait and powders | 1 to 2 hours | Lower airborne toxicity |
Additional Recommendations
If you or someone in the household has respiratory sensitivities or allergies, it’s wise to extend time outside or even temporarily relocate overnight. Opening windows and ventilating the treated space thoroughly helps speed up clearance.
