Ants: The Unwanted Kitchen Guests

Ants are one of the most common pests found in Ottawa homes, particularly during the warmer months. They often invade kitchens in search of food. Carpenter ants, a specific type, can be particularly destructive as they tunnel through wood to build their nests, compromising the structural integrity of your home.

To prevent ant infestations, it’s crucial to keep your kitchen clean and store food in sealed containers. Regularly inspecting and sealing cracks around windows and doors can also deter these persistent invaders.

Rodents: Mice and Rats

Rodents such as mice and rats are not only a nuisance but can also pose significant health risks due to the diseases they carry. These pests are skilled at finding entry points into homes, particularly during the colder months when they seek warmth and shelter.

Effective rodent control includes sealing potential entry points, setting traps, and maintaining cleanliness to remove food sources. It's important to act quickly if you notice signs of rodent activity, such as droppings or gnawed materials.

Spiders: Beneficial Yet Unsettling

While many people dislike spiders, it's important to note that they are beneficial in controlling other pest populations within the home. In Ottawa, common house spiders include the common house spider and the black widow, though the latter is rare.

If spiders become a significant issue, reducing clutter and using natural deterrents like essential oils can help manage their numbers. Regular cleaning also helps remove webs and eggs.

Bed Bugs: The Unseen Bites

Bed bugs have become increasingly common in urban areas, including Ottawa. These tiny pests are notorious for their bites, which can cause itching and discomfort. They are often brought into homes unknowingly via luggage or used furniture.

To protect against bed bugs, inspect second-hand items before bringing them into your home and regularly wash bedding in hot water. If an infestation occurs, professional pest control services are often necessary to fully eradicate them.
