As the seasons change in Ottawa, so do the types of pests that can invade your home. Being proactive with pest control can save you time and stress down the road. Here are some top seasonal pest control tips to keep your home pest-free year-round.

Spring: Ants and Termites

Spring is when many pests, like ants and termites, become more active. These pests are not only a nuisance but can also cause significant structural damage to your home. To prevent them from entering, focus on sealing cracks and crevices in your home’s foundation. Additionally, remove any debris or wood piles from the vicinity of your house.

It's also important to keep your kitchen clean and free of crumbs, as these can attract ants. Consider using natural repellents like vinegar or essential oils to deter them.

Summer: Mosquitoes and Wasps

During the summer months, mosquitoes and wasps become more prevalent. To minimize mosquito breeding, eliminate standing water around your property, such as in birdbaths or clogged gutters. Installing screens on windows and doors can also help keep them out.

For wasps, regularly inspect eaves and other sheltered areas for nests. If you notice any, it's best to contact a professional to safely remove them. Keeping food covered when eating outdoors can also deter these stinging insects.

Fall: Rodents and Spiders

As temperatures drop, rodents like mice seek warmth and food inside homes. To prevent an infestation, seal entry points and store food in airtight containers. Setting traps and using repellents can also be effective.

Spiders may also enter homes during the fall. While most spiders are harmless, keeping your home clutter-free and vacuuming regularly can reduce their presence. Consider installing door sweeps to block their entry.

Winter: Cockroaches and Silverfish

Winter is a time when pests like cockroaches and silverfish seek shelter indoors. These pests thrive in warm, humid environments, so keeping your home dry and well-ventilated is key. Fix any leaks and use dehumidifiers where necessary.

Regularly cleaning and decluttering can also help deter these pests. Pay special attention to basements and attics, as these areas are prime hiding spots.
