How Big Of a Problem Is a Ladybug Infestation In Portsmouth, OH?

Ladybugs aren’t usually number one on anyone’s list of terrible pests to get in your home or business. And why should they be? Their bites don’t really hurt and can’t normally break the skin. They’re not venomous. They don’t sting. They don’t spread disease. They’re even good for the environment. That means as long as they stay outside, you can have as many ladybugs as you want! However, sometimes ladybugs decide to come inside, and when this happens, you can wind up with thousands of unwanted houseguests that you can’t kick out. 

The Ladies Of Portsmouth

Ladybugs are one of the prettiest pests on the block. They come in just about every conceivable color and pattern. Red with black polka dots is the most common look these ladies wear, but they can also come in yellow, pink, orange, grey, and even blue or black. They can have big spots or stripes, and their polka dots might be lighter or darker than their base color. Some ladybugs might have a solid base with no pattern at all. 

When they’re outside, ladybugs offer a lot of benefits to their local ecosystems and farmers alike. They’re sometimes omnivorous, but most ladybug species are primarily predators that feed on soft-bodied insects like mealy bugs, mites, scale, and aphids. They’re particularly hungry for aphids; a single ladybug can consume up to sixty in a day. A decent ladybug population can plow through the aphid problem in your garden without issue. In fact, these hungry little hippos give spiders a run for their money when it comes to natural garden pest control.  

Little Ladies, Big Problems

Ladybugs are great in your garden but not so great in your living room. While it’s not a problem to have one little ladybug crawling across your coffee table, it is a problem when every ladybug in the neighborhood does. Ladybugs hibernate through the winter, and here in Portsmouth, Ohio, our winters can be long and harsh. In nature, ladybugs will find a suitable place like a fallen tree or crevice in a boulder to keep them warm and dry while they hibernate. However, your home is a lot nicer than some cracked rock. Ladybugs are attracted to your home’s warmth, but they’re also attracted to lighter-colored houses that face south, west, or southwest, so houses with these features are more likely to appeal to these insects.

If a group of ladybugs decides your home is a good spot to overwinter, they release pheromones that attract even more ladybugs and mark your home as a safe space for generations to come. Ladybugs that hibernate in your home may become trapped when they emerge from sleep in the spring. They might also lay thousands of eggs around your house. While this won’t put you in any real danger, nobody wants a houseful of any bug. Ladybugs can also release a foul-smelling liquid if threatened, which can stink up your house and stain furniture.

Unfortunately, there’s not a lot you can do to make your home less appealing to ladybugs. They’re attracted to your warm house, and you can’t exactly shut off the heat all winter. Exclusion is your best bet. Take measures like: 

  • Ensure your home’s exterior is free of cracks and holes
  • Put insect mesh over legitimate openings like vents and ducts
  • Make sure window and door screens fit well and are free of tears and rips
  • Install weather stripping under doors and windows
