Top 10 Most Dangerous Insects in Canada

Ticks:These ticks will latch onto humans, dogs, and cats and have the ability to transmit Colorado tick fever virus, as well as tularemia and Rocky Mountain spotted fever.

Spruce Budworm:This cyclical insect also poses major risks to the ecosystem and forests, making it the last on this list of dangerous insects in Canada.

Mosquitos:Each of these types of mosquitoes makes their home somewhere different in Canada. Anopheles and Culex prefer water to reproduce in or near Nova Scotia, southern Ontario.

German Yellow Jackets:These yellow jackets aren’t as aggressive as the other bees on this list, but just as dangerous if a large quantity attacks one person at the same time.

European Fire Ants:Like Africanized honey bees, European fire ants, also known as Myrmica rubra, prefer warmer climates but found their way to Canada. 

Brown Recluse Spider: Brown recluse spiders, or Loxosceles reclusa, live an average of two to four years and are one of only three spiders in North America with significantly poisonous venom. 

Black Widow Spider: It’s imperative to call an exterminator if you find a black widow spider in your home, as it may have made a nest of 50 to 100 eggs.

Asian Longhorned Beetle:Asian longhorned beetles cause significant damage to trees by burrowing and chewing their way through trunks, leaving gaping holes and tunnels. 

Asian Giant Hornet: Asian giant hornets, also known as Vespa mandarinia, have a nasty way of keeping themselves and their hives protected. In addition to stinging, these hornets can also spit venom. 

Africanized Honey Bees:Africanized honey bees received their epithet based on behavior: they’re an aggressive species of bee known to attack in large numbers.
