How To Kill Plaster Beetles


Plaster beetles usually thrive in damp environments, which is why they are sometimes also known as “moth beetles.” Minute Brown Scavenger Beetles is their technical name. This strain of beetles is usually brown to reddish-brown and very small at a mere 1/8 of an inch. Usually, they will have tiny holes on their wing covers, giving the impression that their backs are perforated.

Traits & Characteristics

As already mentioned, this strain of beetles thrives in damp environments since they feed on mold. For this reason, they are usually located in temperate to tropical regions. They can be found all over the U.S. Usually, they prefer to live under logs, in stumps, or in decaying material.

During the cold seasons, a few may find their way into your home due to its warmth and humidity. They will be drawn to the most humid parts of the house such as leaky pipes, the basement, and steaming heating systems. The basement is probably where they are found the most due to its mold-friendly nature.

Should you ever encounter these critters, this is what you might expect: initially, you may notice only a few beetles crawling here and there around your home. In time, however, you will start to notice more and more of them. Upon checking your basement, you may find a small colony near the moldier areas.

How To Kill Plaster Beetles

The first step in dealing with these pests is to eliminate moisture from your home. To start, find the leaks in your house that are allowing mold to grow. These could be leaky pipes or stopped water in the basement. Fix these leaks so that no amount of water or steam is released.

Next, purchase a dehumidifier and place it near your trouble areas. The air will grow dryer and in time the mildew will die off, cutting off your pest’s main food source. Should the problem reach a significant level, insecticide will be in order. Purchase a strong chemical solution and spray your beetles until they are visibly wet. You may have to do this for several days until they are all killed off. Make sure to keep several windows open to allow the pesticide to ventilate. Remember that you will always have the option of calling pest control professional to take care of the issue should it escalate into an infestation.
