Ladybugs and Asian Lady Beetles: What to Expect as Peak Season Approaches

We are all counting down the days until spring is here. While warmer weather brightens everyone’s mood, it also gives pests a chance to invade. During this time, many homeowners might start noticing small insects around windows, lights, and any areas that attract sunlight around your home. The most common bugs you’ll find in these areas are Ladybugs and Asian Lady Beetles. We highly recommend knowing the difference between each one, and why they become active so it’s easier to prepare.

Now that spring is only a few weeks away, take some time to read this article to understand who these insects are, what role they play, and how to manage them as the air gets warmer.

Who Are Lady Bugs and What Do They Do For the Environment?

We know ladybugs as their bright red or orange shells with black spots. Beyond what they look like, they are super beneficial for the environment. These insects feed on several soft-bodied pests, which is good for your plants in the warmer months. A single Ladybug is known to consume up to one thousand aphids over its lifetime.

During the winter, Ladybugs are typically still found outdoors, unless they get inside by mistake. They overwinter in protected natural habitats such as tree bark, logs, leaves, etc. This is their dormant state where they conserve energy until warmer temperatures return. When warmer weather starts creeping in, Ladybugs slowly start becoming active again. This means that they depart from their overwintering environment and travel towards gardens, empty fields, and landscape areas. With their outdoor overwintering style, Ladybugs will rarely cause problems on the inside of your home. In fact, if you spot a Ladybug outside in the early weeks of spring, it’s usually a really good sign. And that sign means that spring is officially here.

Asian Lady Beetles are on the Move

Winter is a time where Asian Lady Beetles thrive, unlike Ladybugs. These bugs are often mistaken as Ladybugs, but they are far from the same. Their behavior, especially in winter and early spring is what sets them both apart.

Asian Lady Beetles originally came from North America to help control pests around crops. Since then, they have widely immersed and adapted extremely well to people’s homes. If you see one but aren’t sure what they look like, they vary in color from pale orange to deep red, and sometimes have spots or none at all. I know they look very similar to Ladybugs, which is
why people struggle to tell them apart. Another way to identify the beetle is by the black “M” or “W” shape right behind the head.

While Ladybugs are seeking shelter outdoors, Asian Lady Beetles are doing the opposite. So, don’t be surprised if you find some overwintering in your attic or kitchen this winter. In the fall, they likely appear on sunny, lighter-colored walls, and enter through small gaps around your home. Make sure you have your trusted pest control company seal those up for you as soon as possible! If they get inside, they will find a way to cram into walls, attics, and other tightly fitted areas throughout the winter.

Once they wake up, they’re not reproducing or infesting your home. They’re simply responding to warmth and light while trying to find the easiest way to get back outside.

Why We Are Seeing Them Now

Early spring is a peak time for indoor sightings of Asian Lady Beetles. Rising temperatures and longer sunny days give them the okay to come out of hiding. Some common gathering spots include windows, ceilings, or any places with light shining through, so they can escape. Please remember that they don’t cause any structural damage or reproduce inside your home. It’s best to avoid crushing them, so they don’t release a yellowfish fluid that can either stain walls or cause an unpleasant odor.

Here’s What You Can Do:

We recommend you take action now by calling U.S. Pest Protection. We’ll handle the Asian Lady Beetles before they become more active.
We will complete the following:

  • Safely remove all indoor beetles.
  • Seal any and all entry points up to avoid more beetles coming inside.
  • Recommend reducing indoor lighting. Keep all areas surrounding windows clean and organized, and minimize bright lighting.

Looking Ahead

As you can see, Ladybugs and Asian Lady Beetles both play an important role outside. When spring arrives, they all help aphids and other plant pests remain controlled, which reduces the need for chemical treatments in gardens and landscapes. Trust me, we want you to continue having the best looking landscape on the block, too.

Understanding the seasonal behaviors of these bugs will make it ten times easier to respond to unpleasant situations.
