At PSI, we understand how concerning it can be to see wasps gathering around your home or discover wasp activity building around entrances, decks, or rooflines. Our team provides professional wasp nest removal and control services for yellowjackets, paper wasps, and hornets, designed to safely address the activity and reduce the risk of stings around your property.
Call (250) 727-1948 to schedule your inspection. Rapid-response service is available across Greater Victoria to locate active nests and determine the safest way to remove them.
When an active wasp nest appears around the home, calling for professional removal helps determine the safest way to address the situation. Increased wasp activity near rooflines, under eaves, around decks, or near entrances often signals that a nest is established nearby, and movement around these areas can quickly trigger defensive behavior from the colony.
Addressing an active nest early helps reduce the risk of stings and keeps outdoor areas around the home more comfortable for families and pets.
When our technicians arrive, the first step is identifying the nest location and assessing the level of wasp activity around the structure. Nests may be found under rooflines, inside wall spaces, or attached to outdoor structures where wasps are regularly entering and leaving.
Because yellowjackets, hornets, and paper wasps behave differently near the nest, the approach is adjusted based on the species and where the nest is located. Protective equipment and appropriate treatment methods are used to address the activity while keeping the situation controlled around the home.
Once the nest has been addressed, homeowners are given a clear explanation of what was found and what signs to watch for as the season continues. This careful approach helps resolve the activity while reducing disruption around entrances, patios, and other outdoor areas.
Wasp nests are commonly found around rooflines, under eaves, inside wall spaces, in the ground, or in nearby trees and shrubs where activity can develop close to the home.
Homeowners in Greater Victoria most often encounter yellowjackets, paper wasps, and bald-faced hornets, each of which chooses different nesting locations. Yellowjackets frequently nest in the ground or inside wall cavities and become more defensive as their colonies expand through late summer. Paper wasps build small open nests under eaves, soffits, and porch roofs, while bald-faced hornets construct enclosed, football-shaped nests in trees, shrubs, or along rooflines.
Recognizing where nests are forming helps explain increased wasp movement around the property and allows the situation to be handled safely.
Pest Scene Investigations has long experience working with local wasp behaviour and nesting patterns across Greater Victoria and the South Island. Our licensed technicians operate under BC pest management standards and follow practices shaped by years of field work in attics, rooflines, wall spaces, yards, and outbuildings throughout the region.
Before work begins, we explain what was found and how it will be handled so homeowners understand each stage of the visit. The same careful approach applies whether the nest is small or well established. Families across Victoria rely on our consistent service when wasp activity begins around their home.
Safety remains central to our work. Our methods follow BC’s Integrated Pest Management standards and are applied carefully around homes, gardens, and areas where children and pets spend time. The goal is to remove the nest and settle the space without creating additional concerns for the people and animals who live there.
Homeowners who want to prepare for a visit or reduce future nesting can review additional resources, including links and documents, common questions, and prevention tips available through our learning section.
These explain how to get your home ready for treatment and outline each step in the process.
Straightforward answers based on the work our licensed team carries out in Victoria.
Practical steps that help reduce the chance of new nests forming around the home.
Increased wasp traffic around a specific area is usually the first sign, particularly near rooflines, under eaves, around decks, or close to entrances. Wasps repeatedly returning to the same spot rather than passing through confirms that a nest is established nearby. Defensive behaviour when walking near a certain area of the property, such as wasps orienting toward you, means the colony is active and the nest is close.
The three species most common in Greater Victoria are yellowjackets, paper wasps, and bald-faced hornets, and the type matters because each nests and behaves differently. Yellowjackets nest in the ground or inside wall cavities and grow increasingly defensive as their colony expands through summer. Paper wasps build small open nests under eaves and soffits, while bald-faced hornets construct enclosed, football-shaped nests in trees or along rooflines and are significantly more aggressive near the nest.
Attempting to remove a wasp nest without professional equipment carries a genuine risk of stings, particularly with yellowjackets and bald-faced hornets, which can sting multiple times when the colony is disturbed. Some people experience a severe allergic reaction without any prior warning, which is why the risk is not worth taking when professional removal is available. The approach a licensed technician uses is also adjusted based on the species and nest location, which matters more than most homeowners realise before they try it themselves.
For wasp nest removal in Victoria, earlier in the season is always better. Victoria’s mild coastal climate means queen wasps emerge and begin building nests earlier than in most of BC, and colonies grow steadily through summer into increasingly defensive populations. A nest found in late spring or early summer is far easier and safer to address than one that has been active for several months by late August.
Wasps defend the colony from anything they perceive as a threat, and movement near an active nest is often enough to trigger that response. Yellowjackets are particularly reactive and will sting repeatedly without needing direct contact with the nest. That defensive behaviour intensifies as colonies grow through late summer, so a nest that seemed manageable in June can be considerably more difficult to approach by August.
Wasps found inside the home, particularly yellowjackets, often indicate a nest established inside a wall cavity or void space within the structure. This is a more complex situation than an outdoor nest because disturbing the wall area without proper equipment can trigger an immediate defensive response from the colony inside. Calling for an inspection first allows the nest location to be identified before any work is done.
Yellowjackets that nest inside wall cavities can damage insulation and interior building materials as the colony expands and workers chew through the surrounding structure. The damage is secondary to the immediate safety concern, but a nest left inside a wall for a full season can create problems that go beyond the wasps themselves. Addressing a wall cavity nest promptly limits both the risk to the household and the extent of any structural impact.
Wasps do not reuse old nests, but new queens will often return to the same general area if it offered good shelter the previous year. A spot under an eave, in a wall void, or in a sheltered corner of the yard that hosted a nest once is likely to attract activity again the following spring. Removing the old nest and addressing what made the site attractive reduces the chance of the same area being chosen again
PSI handles wasp nest removal across the south island, from Sidney and the Saanich Peninsula through Greater Victoria and out to Sooke, along with the Gulf Islands and into the Nanaimo area. Wasp activity runs through the warmer months across this region, whether the nest is in an urban backyard, under a rural outbuilding, or inside a wall cavity. The same licensed team responds across the full service area.
Before the technician leaves, they will explain what was found, how it was addressed, and what signs to watch for as the season continues. A reduction in wasp activity around the treated area in the days that follow is the practical indicator that the nest has been dealt with. If activity continues or resumes, calling the team back to reassess is the right next step.
