Identification of Plaster Beetles

Plaster Beetles are tiny insects, typically measuring just 1 to 3 mm in length. They are usually brown or black in color and have a flattened body structure. Their antennae are club-shaped, with the last three segments larger than the previous ones. Their small size and color may make them hard to spot unless there’s a significant infestation.

Life Cycle & Habits

Plaster Beetles prefer damp environments and are often found in areas where mold and mildew are present, which serve as their primary food source. They thrive in moist plaster or wallpaper, hence their name.

Plaster Beetles can reproduce rapidly in favorable conditions, causing infestations to occur seemingly out of nowhere. Their life cycle from egg to adult usually takes a few weeks but can vary depending on environmental conditions.

Extermination Techniques

Controlling Plaster Beetles often involves several strategies:

  1. Reducing Moisture: Ensuring your home is adequately ventilated and damp-free is crucial.
  2. Mold Control: As the beetles feed on mold, removing this food source will discourage infestations.
  3. Pesticides: Professionally applied pesticides can help in extreme cases but should always be used as a last resort due to potential health risks.
  4. Professional Help: If infestations are severe or repeated, enlist the help of professional pest control services.
