Non-Chemical Management
- Use a USDA lady beetle trap. Beetles are attracted to a black light and captured in an attached bag. Insects are then collected alive for later release or disposal. Detailed technical instructions and diagrams for constructing the trap are available on an ARS web site in PDF (portable document format) at: http://www.ars.usda.gov/is/br/lbeetle/001030.trap.pdf
- Ensure tight-fitting screens, windows, and doors. Locate entry points and seal up cracks and crevices via caulking. Concentrate efforts on south and west faces of infested structures.
- Vacuum complete clusters from walls during autumn. Dispose of vacuumed beetles far away from the building; otherwise they will return.
