Are Ladybugs Dangerous?

Posted by Cat Heisler

Ladybug, ladybug, fly away! It’s something we said for fun as kids, but come fall you may be meaning it!

Snug as a Bug

In the fall, ladybugs begin looking for places to hibernate, and they tend to think our homes look pretty nice!  They’re especially attracted to light-colored homes and older homes, but they are attracted to the heat reflected by all homes.

Bug Perfume

The problem with ladybugs is that once one decides your home is a nice play to stay the winter, it releases pheromones to attract other ladybugs — from as far as a quarter-mile away!  That’s some pretty strong perfume.  It can also last for years after, so if you end up with a ladybug infestation once, you’re likely to face one again.

Annoying but not Harmful

The good news about ladybugs is they’re actually one of the Good Bugs.  They’re not poisonous to humans, and they eat aphids and plant mites that can destroy your roses and other garden plants.  They also aren’t destructive insects like ants or termites.  That being said, they can be toxic to some animals, so they’re still not something you want infesting your home.

Get Them Out and Keep Them Out

Making sure your home is properly sealed and insulated is an excellent step toward keeping them out of your home.  Repair any window trim or door jambs and caulk small cracks where they could get in.

Another option is to put out a ladybug house for them to use during the winter.  This may be a good option if you’ve had infestations before.  It’s not a fail-safe, but it’s worth a shot.

If you’ve got ladybugs, know that they’ll pack up and leave when spring hits.  You may find the dry air in your home during the winter ends up killing them due to dehydration.  Whether they’re alive or dearly departed, the easiest way to get rid of them is to use a shop vac to suck them up.  Use a new bag and release them outside.
