Our Method
Since every spider situation is unique, we’ll come up with a custom solution for you. With over 10 years of experience spraying for spiders, we’re Ontario‘s leading provider of spider control services. Learn how we keep spiders (and other common household pests) out of your home:
We’ll perform a walk-through around your home, checking entryways and hotspots for signals of spider activity. If you have an active infestation, we’ll begin eliminating spiders during this initial visit.
We’ll begin by reducing favorable spider conditions. This includes, but is not limited to, decluttering your yard and crawl space, and removing any ground covers against your walls. We’ll sweep the perimeter of your home (windows, doors, utility boxes, etc.).
If spiders are coming indoors hunting for prey, we’ll carefully apply a residual insecticide around all entry points and the perimeter of your home. We’ll also spray along baseboards, in corners, and under furniture. These two treatments keep spiders where they belong… outdoors.
If you’re dealing with a large spider problem, we’ll also apply insecticide dust in your attic, between your wall voids, and under your baseboards. We use a cobweb duster head to brush the dust into hard-to-reach areas like the corners of your basement, garage, and porch to ensure full coverage.
Finally, we’ll use glue boards to catch spiders and monitor the population. We’ll place these in hotspots and areas of activity. This step allows us to ensure your spider control program is effective and make adjustments as needed. Our goal is to keep your family safe and your home spider-free!

Pest Control in St. Thomas
St. Thomas includes historic neighbourhoods, established residential streets, newer subdivisions, commercial properties, and green spaces. Pinafore Park, Waterworks Park, and the surrounding Kettle Creek watershed contribute to the city’s varied landscape.
Spider activity around individual properties depends on more than the surrounding neighbourhood. Exterior lighting can attract insects, while sheltered soffits, window frames, porch ceilings, and garage corners provide suitable locations for webs.
Older St. Thomas homes may experience recurring activity around basement windows, foundations, porches, utility openings, and storage areas. Newer detached homes and townhouses can develop hotspots around attached garages, entrance lighting, soffits, patio doors, and sheltered building edges.
Commercial buildings and multi-unit properties may also experience spider activity around illuminated entrances, balconies, exterior windows, service areas, and protected structural corners.
Mosquito Man’s spider-control process includes site inspection, sanitation and accessible web removal, liquid treatment, dusting for suitable locations, and monitoring. Treatment is adapted to the activity and conditions identified at each property.
Step 1
A technician inspects accessible interior and exterior areas for active spiders, webbing, egg sacs, likely entry points, protected harbourage, and recurring hotspots.
Inspection can include windows, doors, soffits, eaves, porches, decks, garages, basement windows, foundations, exterior lighting, utility openings, baseboards, and other locations where spiders have been noticed.
The findings help determine whether activity is concentrated around exterior surfaces, structural openings, or protected interior spaces.
Step 2
Accessible webbing is swept from relevant perimeter areas, including windows, doors, utility boxes, and other suitable surfaces.
The technician can also identify conditions that provide shelter, such as clutter, stored materials, ground cover against exterior walls, and vegetation touching the building.
Addressing these conditions supports the treatment plan beyond removing visible webs.
Step 3
Where appropriate, residual liquid treatment is applied around entry points, the building perimeter, and active structural areas identified during inspection.
Potential treatment locations include windows, doors, cracks, crevices, soffits, eaves, foundations, porches, garages, baseboards, and corners.
Product selection and application depend on property conditions and applicable label directions.
Step 4
For suitable concealed or difficult-to-reach locations, insecticide dust can supplement liquid treatment.
Potential areas include attic spaces, wall voids, spaces beneath baseboards, basement corners, garages, porches, and other protected structural harbourage.
Dusting is selected according to the activity found rather than applied indiscriminately.
Glue boards may be placed in suitable hotspots and active areas to monitor continuing spider activity.
Monitoring helps determine whether activity continues in the same locations and whether the control program requires adjustment or maintenance.
Exterior activity is reduced, while spiders may remain in protected structural spaces.
Warming conditions increase insect and spider activity around buildings.
Exterior web-building becomes increasingly noticeable as insect activity increases.
Exterior activity can continue while protected structural areas become increasingly relevant.
Colder conditions reduce exposed activity, but protected spaces remain available.
St. Thomas properties near mature gardens, parkland, and wooded areas can experience changing insect activity throughout the warmer months. Exterior lights, porches, decks, windows, and garages may become recurring web-building locations. As temperatures fall, basements, garages, utility spaces, and other protected structural areas deserve greater attention.
St. Thomas includes historic central neighbourhoods, established suburban communities, newer residential development, and properties near parks and natural areas. Spider-control priorities can differ according to building age, surrounding vegetation, exterior lighting, and structural features.
These examples demonstrate how treatment planning can change according to property conditions. They are illustrative situations rather than actual customer case studies.
St. Thomas properties range from historic homes and established residential streets to newer subdivisions and commercial buildings near parks and wooded areas. Spider activity can concentrate in different locations depending on building design, exterior lighting, vegetation, nearby insect activity, and available shelter.
A property-specific approach begins by identifying recurring web locations, likely access points, and the conditions supporting activity before selecting appropriate treatment areas.
