| Who |
The Asian Lady Beetle
Latin name: Harmonia axyridis
|
| Why |
- They are attracted to light colored buildings
- Highly illuminated or southwestern-facing sides
- Buildings close to trees or woods
|
| How |
- Asian lady beetles congregate in large numbers in the fall
- They cluster on the side of buildings eventually working their
way into cracks and crevices, or into the window panes
- Then during the winter they "hibernate" within the walls until
warm, spring- like weather when they begin to crawl about
- Unable to find their way back outside in search of food and
water, they collect on windowsills attracted by the UV rays
|
| Control |
- Seal them out by caulking and repairing openings
- Vacuum or sweep them as they emerge, avoid alarming them because
they can emit a yellow fluid that stains
- Also empty the vacuum bag outside immediately afterwards because
dead insects left in the bag emit a permanent odor
- New Ladybug trap? USDA scientists have designed a live catch
trap for these insects. Stay tuned for more information on this
innovation

Cornell Cooperative Extension of Suffolk County has a new Pest Management
Program designed to address changes resulting from the newly passed legislative
bill that phases out pesticide use on County properties and in County
buildings.
We are working hard to provide you with a comprehensive educational program
to keep our County the best! Look to us in the future - we're here to
help.
