Plaster Beetle (Family Lathiiridae)
Small reddish or black beetles often found weakly flying in homes during late summer. Plaster Beetles are from 1.5- 2.5 mm in length with ridged, wide wingcases.
Plaster beetles feed on mould or mildews and are attracted to anything that is musty smelling with newly constructed homes, damp areas in basements, bathrooms and damp commodities (such as grain), often affected. Eggs are laid singly and take approximately 5 weeks to complete the lifecycle.
Insecticidal treatments may not provide a total solution against this pest. Flying insect sprays will kill the adults and a residual insecticide spray should be applied to walls and floors. For longer term control running dehumidifiers or checking vents for proper screening will help reduce migration.
