NASHVILLE, Tenn. (WKRN) — Seeing spots in your house? You're not alone. Swarms of little insects, which resemble ladybugs, are invading homes across the Volunteer State.

The pests, known as Asian lady beetles, seek warmth during the fall months, gathering on buildings, and if given the opportunity, they will move inside.

The pests are often mistaken for ladybugs, but they are very different. Here's everything you need to know when it comes to the unwelcomed residents.

What are Asian lady beetles?

Asian lady beetles (Harmonia axyridis) are native to Asia and the first populations were found in Louisiana in 1988, per the U.S. Department of Agriculture. The insects are reportedly beneficial since they eat agricultural pests, like aphids, which can harm crops.

What's the difference between ladybugs and Asian lady beetles?

According to U.S. Pest Protection, Asian lady beetles have a distinctive "W" or "M" marking on the area behind their head. In addition, Asian lady beetles appear to be more orange or tan, while ladybugs are typically vibrant red.

Unlike ladybugs, which are mostly harmless, a large infestation of Asian Lady beetles can reportedly produce an unpleasant odor. The beetles can also bite, and American Pest Control Inc. said the bites can be mildly painful, but don't cause any diseases or lasting harm.

Can you prevent them from entering your home?

To prevent an invasion, pest control experts recommend sealing any cracks or crevices where insects may enter. This can include caulking doorframes, repairing damaged window screens and adding rubber seals to the bottom of doors.

Experts also recommend beginning a routine pest treatment plan to get rid of the beetles. The treatment can reportedly interrupt the bug's pheromone cycle to make sure they can't find their way back to your home.

How to get rid of them

Vacuum, don't crush — this is the method recommended by pest control companies. If crushed, Asian lady beetles can release a yellowish fluid that will stain surfaces.

Some homeowners may try DIY repellents, such as vinegar, essential oils, or cloves, but experts say those solutions are only temporary.
