Our process


Step 1: Boxelder Bug Heat Treatment


  • Physical

  • Instantly kills all bugs and eggs treated.

  • Mediates the risk of pesticide resistance.


  • No residual protection.

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

  • Not sufficient without other complementary extermination techniques.


Step 2: Boxelder Bug Powder Treatment


  • Physical + Chemical


  • Power duster


  • A fine silica dust insecticide is injected into all crevices and wall cavities through electrical sockets and gaps underneath baseboards.

  • Injected into any wall void or drain where boxelder bug are particularly active.


  • Cuts up the boxelder bug abdomen.

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

  • Essential lasting protection.

Step 3: Boxelder Bug Spray Treatment

  • A fine mist of residual spray is applied to the backs, sides and bottoms of box springs, mattresses, bed frames, couches, chairs, baseboards, door jambs and floors throughout the home.


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

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

  • Fully approved by the Ontario Ministry of the 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 companies offer to do a “follow-up spray” two weeks after the first treatment. While this may seem extra thorough, boxelder bugs can remain beneath inside wall voids during winter for several months

  • While hibernating boxelder bugs can remain hidden in wall voids and cracks and crevices around the home for several month

  • By this time the cheap treatment will have long worn off and the new population of boxelder bugs will be free to re-infest your home.

  • These budget services can breed pesticide resistance in the boxelder bugs in your home, making future treatments increasingly challenging.

  • Using high quality, long residual insecticides, varied extermination methods, and thorough single applications is the key to our success at Addison

Beware of Misclassification

  • Because of anatomical similarities boxelder bugs are easily mistaken for various true bugs and outdoor insects

    • kissing bug

    • assassin bug

    • milkweed bug

    • red-shouldered bug

  • The three longitudinal red lines on the pro-thorax (behind the head) of the boxelder easily distinguishes it from these other species

  • Since boxelder bugs tend to multiply more severely than these species, proper classification will help in considering potential treatment steps

  • Consult a pest control professional for proper identification
