Key Facts about Spiders

  • Many customers who suffer from an extreme fear of spiders, called arachnophobia, use our spider treatment to keep them protected from spiders year-round.

  • The most common species of infesting spider in Ontario are the common house spider (Parasteatoda tepidariourum) and the barn funnel weaver (Tegenaria domestica); they are most active in late spring to summer.

  • These spiders pose an infestation risk because of the house spider’s high reproductive potential ( approx 3760 offspring in her lifetime!) and the barn funnel weaver’s long lifespan (up to 7 years).

  • These spider species live almost exclusively in and around human structures, including homes, apartments, garages and barns

  • Spiders feed on insects, and can help to reduce the number of other insect pests in your home

  • Neither of these spiders are poisonous, and only bite humans if they are threatened

  • Spiders are arachnids which are differentiated from insects because they have 8 rather than 6 legs, and have 2 main body segments (cephalothorax and abdomen)


Our process


Step 1: Spider Heat Treatment


  • Physical


  • Handheld heat treatment gun


  • Direct heat applied locally to areas of spider concentration such as basements, balconies, storage rooms, window sills, under beds and furniture concentration


  • Heat kills spider eggs

  • No damage to furniture

  • Instantly kills all spiders and egg sacs treated.

  • Avoids pesticide resistance


  • No residual protection

  • Only kills the spiders and eggs that are visible and accessible to technicians

  • Not sufficient without other complementary extermination techniques.


Step 2: Spider Powder Treatment


  • Physical + Chemical


  • Power duster


  • Fine silica dust insecticide injected into all crevices and wall cavities through electrical sockets and gaps underneath baseboards

  • Electrical items at risk of infestation, such as a power bars, or electronics in storage are treated with powder


  • Cuts up the spider abdomen

  • Coats the insides of the wall cavities to create a protective powder barrier around your home.

  • No spiders can spread to or from attached houses, adjacent apartments or condo units.

  • Essential lasting protection.

  • Fully approved by the Ontario Ministry of the Environment, safe and non-toxic for humans and animals of all shapes and sizes.


  • Only suitable for crack and crevice treatment.


Step 3: Spider Spray Treatment


  • Chemical + Residual


  • Precision surface sprayer


  • A fine mist of residual spray applied throughout infested area, including basements storage spaces, balconies, decks as well as the backs, sides and bottoms of beds and furniture throughout the home


  • Kills spiders on contact and remains active as a protective surface treatment to continue to kill spiders as they come out of hiding

  • Keeps your home and furniture protected for up to 6 months

  • Fully approved by Ontario Ministry of Environment, safe and non-toxic for humans and animals of all shapes and sizes


  •  If used improperly, may promote pesticide resistance



Beware of Discount Pest Control

These companies use low quality or low concentration surface sprays with only 10 to 14 days of protection.

  • The tip off is when they offer to do a “follow-up spray” two weeks after the first treatment. While this may seem extra thorough, spiders may have adequate prey to remain hidden for several weeks.

  • By this time the budget treatment will have long worn off and the new population of spiders will be free to re-infest your home. These budget services can breed pesticide resistance in the bugs in your home, making future treatments increasingly challenging.
