When we think of winter pests we usually think of squirrels, raccoons, rodents, and spiders. Ladybugs aren’t usually at the top of our list, but they are one of the most common winter pests. During the warmer months of the year, ladybug populations grow as they feed on the foliage and aphids. With the onset of colder weather, these food sources diminish, forcing them indoors in search of food and warmth. Ladybugs will seek shelter under rocks, leaves, and timber, and inside buildings and homes.

Ladybugs aren’t considered a threat to humans. However, they have been known to cause allergic reactions in some people and aggravate asthma. They also give off a smelly, yellow colored fluid that stains anything it comes in contact with.

The best way to prevent ladybugs is to eliminate ways for them to get into your home. Make sure the cracks around your windows, doors, siding and utility pipes are sealed. You can use a silicone or silicone-latex caulk to seal. Repair and replace damaged screens on both windows and doors. If you already have ladybugs in your home, the best way to get rid of them is with a vacuum cleaner. Empty the vacuum bag into a trash bag and seal it tightly and dispose of it outside immediately. If you suspect you have a ladybug infestation, contact a professional pest control company to provide you with a thorough evaluation and treatment plan.
