What Draws Ladybugs into Sudbury Homes?
If you’re noticing the signs of ladybugs congregating on the sides of your Sudbury home, it’s a sign that the problem is about to become bigger than expected. Asian lady beetles are characterized by an orange color instead of the red color found on ladybugs. These invasive pests were brought to help reduce insect pests within farmland and areas where crops or gardens were destroyed. Unfortunately, Asian lady beetles can spread fairly quickly and don’t always have the necessary predator nearby to reduce their activity. As they locate warm areas on the exteriors of homes, they will begin to seek out points of entry.
As temperatures cool, Asian lady beetles will swarm Sudbury homes in an effort to overwinter within the walls. As their presence outside grows, you’ll begin to notice the signs of a few crawling along ceilings, near windows, and hiding within recessed lighting. This is unfortunately a sign that the Asian lady beetles have successfully found one or multiple points of entry into your indoor living spaces. While they typically hide within wall voids until springtime, the warmth from indoor heating encourages them to leave their overwintering spaces.
Reduce Asian Beetle Activity at Your Sudbury Home
While it can feel complicated to reduce the presence of Asian lady beetles at your Sudbury home, there are a few steps you can take to get ahead of the pest problem. For proactive measures, locate and seal points of entry around your home. Asian lady beetles will typically enter homes around window openings, underneath door sweeps, and through attic vents or external utility lines. Use caulk and sealants around these areas to reduce points of entry, and consider replacing worn mesh screens and door sweeps. For areas around common entrances and exits, consider using diatomaceous earth and botanical oil sprays to reduce and repel Asian lady beetle activity.
For Asian lady beetles that are already inside the indoor areas of your Sudbury home, it’s helpful to use a vacuum to capture them instead of trying to squish them with a broom or shoe. Asian lady beetles will leave orange stains behind and emit an odor when crushed, which can result in frustrating smells and stains to manage. Handheld vacuums and shop vacs are popular for capturing Asian lady beetles, but it’s important to use an option that you can set aside strictly for Asian lady beetles to avoid the issues of staining within your main vacuum cleaner. Once you have vacuumed the Asian lady beetles, it’s essential to quickly move them outdoors or find a way to seal the hose. If not, Asian lady beetles will find a way to crawl out of the vacuum and back into your indoor living spaces.
