Plaster Beetle (Lathridiidaespecies)
All members of this family feed on moulds and fungi and require damp, high humidity conditions to exist. Many are found out of doors, beneath loose bark, amongst dying and rotting leaves, and frequently in stacks of sawn timber. They occur indoors wherever suitable conditions exist. The Plaster Beetle may also feed on moulds on damp plaster, hence the name.
Plaster Beetle Removal
Insecticide 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.
