CALGARY- It’s a been a busy season for pest control companies in Calgary, who have been coming face-to-face with everything from voles and skunks to ants and wasps. And in some cases, homeowners trying to deal with the problems themselves are doing more harm than good.
Bill Martin from Martin’s Pest Control spent Tuesday at an apartment building in Sunalta, where wasps built a nest inside the ceiling of a second-floor balcony. He says the biggest mistake people make is sealing the nest opening instead of injecting a chemical powder into the opening.
“They’ll spray foam into the house and think that they’ve gotten rid of the wasps nest, and usually two or three days later they’ll call us because they’ve got them coming out of the lights in the basement or in the mechanical room or out of the walls,” he explains.
“Wasps, hornets and bumble bees are unrelenting.”
The best way to prevent wasps from building a nest is to hang a yellowjacket trap in the spring, and avoid those bags you can buy at hardware stores that look like a nest.
