You are reading the Original Version (CLB5+) Read Simple Version (CLB3-4) Pests and critters will be seeking warmth in winter just like us. As the weather gets colder, some insects and furry animals will be looking for shelter, food sources, and mates. Sometimes they find all these in our homes. To prevent your house from becoming a wonderland for them, detect them early and protect your home. Here’s how to stop pests before they become a problem. Insects mostly seek shelter in the damp areas of your home. If you live near a lot of trees or have a garden, centipedes and millipedes can move into your basement, bathroom, and other moist areas of the house. Bugs and ants, as well as cockroaches and spiders, may find refuge in your walls. The worst kinds of insects are bedbugs and ticks. Some could find their way into your home during warmer weather and stick around until winter. If you see rodents like mice, rats, and raccoons near your home, or if they’re using your yard as a playground, it’s possible that they are nesting in the leaves and plants. They might also be using your basement as their winter headquarters. Some insects like centipedes and millipedes are harmless. They can even be useful since they eat smaller insects. However, ladybugs, boxelder bugs or termites may bite or leave unsightly stains and bad odour. The worst ones, like ticks and cockroaches, are carriers of diseases, bacteria, and other viruses. Meanwhile, rodents, aside from being possible carriers of rabies, can ruin property. They can snack on your cables, gnaw holes, and damage your house. They also leave smelly and unsightly droppings and urine. Clutter makes your home attractive to pests. Mice start stockpiling food (food scraps, paper, and other garbage) in the fall. If you have a steady supply of these, mice will stick around. Prevent them from nesting in your backyard by clearing out weeds, grass, and leaves. Remove junk from your garage so rats will not hide there. Pick up trash strewn around your area. Dispose of garbage regularly and make sure that your garbage bins have tight-fitting lids. Inside your home: Check your walls, corners, gutters, and pipes to see if there are cracks or holes through which pests can enter. Inspect windows, pet doors, chimneys, and other possible openings and keep them closed during winter. Seal all small openings to your home. Use epoxy to fill in small cracks or holes. If you see tell-tale signs of infestation like mouse droppings, gnawed food, or if you have insect bites, then it’s confirmed that you have an unwanted house guest. You can use traps, like poisoned baits or glue traps. Make sure to place them in areas that your kids or pets cannot reach. If you decide to use pesticide, see that you are using the right product for the type of pest that you are dealing with. Read Use pesticides safely or can ask advice from your local hardware or supplies store. Make sure to follow all label directions. If you live in an apartment, inform your building manager before using measures that may affect your neighbours. Keep your surroundings clean all year round. Inspect your home periodically to ensure that everything is sealed and secure. If you’re still worried about an infestation, consult a pest control expert. Don’t forget to ask for your building manager’s help first, if you live in an apartment. Please login to tell us what you think.Skip to:
