Top Winter Pests to Watch Out For

As we get into the cold months of the year, our habits will change quite a bit making us house dwellers who avoid going outside. This behaviour change is not limited to humans, as other animals also avoid the cold by seeking warm shelter. For pests, this warm place is your home, which means you could find yourself sharing your house with some unwelcome guests.

To help you cope with pests that might invade your home this winter, we have compiled a list of the most common suspects and a few tips on how best to avoid them.


Roaches are generally an all year problem, but for a house that was free from them, winter could bring an added risk of infestation. This is because cockroaches that were outside during the warmer months will be looking for somewhere to hide as the temperatures plummet. And once cockroaches move in, they won’t move out. You can keep them out by:

1.    Sealing all the gaps around your doors, windows and where utility lines enter your house.
2.    Screening or sealing all the sewer vents and drain lines that lead to your house.
3.    Making sure the walls of your home are clear of places where roaches can hide such as stacked firewood, mulch, shrubs and other vegetation.

Most people think that rodents hibernate or die off during winter, but they don’t. Rodents are resilient creatures that can survive adverse weather conditions, and they don’t hibernate. This means that the threat of rodent infestation is rife all year long but more so during winter.

Preventive measures you could take against these critters are:

1.    Sealing any holes that rodents could use to gain access into your home.
2.    Keeping your food secure by storing it in sealed metal or glass containers – rodents can chew through plastic.
3.    Disposing of your food waste properly in tightly covered bins.

Hornets and wasps

Hornets and wasps are not winter pests so they won’t be much of a problem during this time. The queen, however, comes inside to hibernate as the weather gets colder. If the she survives the winter, then you might have a very big problem during spring when the queen is starting a new colony as she might decide to build the nest inside your home. To prevent wasps and hornets from entering your home, make sure that roof vents and soffits are inaccessible by screening them.

These are also non-active winter pests that become a problem when the weather warms up. Once they get into your home, they lay eggs which hatch into larvae in the spring. Moth larvae are known for their destructive eating habits such as feeding on fabrics. To keep these pests out:

1.    Make sure you keep unscreened windows shut.
2.    Screen all vents and seal gaps that could expose your home to moths.

Even with these preventive measures, pests might still find a way to sneak into your home. If they do, Pestrol Pest Control has got you covered. We provide, safe, effective and easy to use DIY pest control solutions so that you can get rid of any pest invader before they start causing trouble.
