Spider Control

Ontario, OR is home to some nasty spiders, including Hobo Spiders, Black Widow Spiders, and Wolf Spiders. Our pest control service includes treatment for spiders, and we guarantee the results. We target the places where they live and breed so that you don’t get surprised by a spider crawling across the floor too often. If you do see them between regular services, call us back, we’ll come out for free.

Ant Control

One of our most common spring visitors, ants come into an area looking for food, and once they find it, watch out. They’ll set up a pheromone trail and soon you’ll have thousands crawling around. Depending on the species, using a random spray you buy at the store may actually exacerbate the problem and make the colony break into smaller satellite colonies that are even harder to get rid of. If this sounds like you, ant control is only a call away!

Cockroach Control

Roaches have the uncanny ability to be absolutely disgusting and interesting at the same time. Not too many things can send shivers down your spine quite like cockroaches. It’s important to have cockroach control Ontario because they can repopulate quickly, are extremely hard to get rid of, and carry all kinds of bacteria and diseases wherever they go. If you need cockroach pest control, contact Averse Pest Control today.

Rodent Control

As the temperature changes, rodents tend to want the same thing as us- a nice warm place to live with an abundance of food. They can squeeze into impossibly small cracks, so it’s important to seal up the exterior well to prevent a rodent infestation in the first place. Mice control isn’t just a one-time thing like you might think. Unfortunately if you see a mouse or signs of a mouse in or around your home, there are probably many more nearby. This is why it’s important to have year round protection so that we can take prevention measures and take care of any that do get inside.

Wasp Nest Removal

Having pests isn’t just an annoyance, sometimes it can be painful! Especially if you have kids at home, make sure the wasps are gone so they can avoid getting stung. Be sure to let us know if you have a play set that needs to be treated as well, we’re happy to do that for you as well as part of our home pest control service.

Mosquito Control

Mosquitoes have caused more deaths than any other insect in the history of the earth. They spread diseases like West Nile and Malaria, among others. And they just plain suck to have around (no pun intended). This is one reason why it’s important to have mosquito pest control, especially during peak mosquito season. Averse Pest Control offers the best mosquito control Ontario has, and we are happy to either do recurring summer treatments or one-time treatments for special occasions like wedding receptions, barbecues, etc. Give your local mosquito control company a call and set up an appointment today!
