Facts, Identification & Control
What Do They Look Like?
- Size: Adult beetles are about 1/4 inch long.
- Body & Head: Adult bodies are oval and shape while their heads are not visible when viewed from above. The larval stage of this beetle looks like a small grub.
- Color: Adults are reddish-brown or darker in color.
How Did I Get Furniture Beetles?
Furniture beetles are one of the many wood boring beetles that are included in the powderpost beetle group of insects. A furniture beetle lays eggs inside crevices in wood, so people may bring the pests into homes within infested furniture. Larvae develop inside timber and exit once they mature, moving into other areas of the home. Moist structural beams can attract these insects as well, so crawlspaces are common sites for wood infested by these pests.
How Serious Are Furniture Beetles?
Larvae bore deep into lumber, leaving behind wood dust and creating exit holes when they emerge as adults. Eating both hardwoods and softwoods, they infest furniture as well as framing, flooring, and other items. Correctly identifying and treating the pests often requires a professional.
Signs of Infestation
The presence of the common furniture beetle is recognized by small, 1/8-inch diameter holes that are surrounded by fine powder-like “sawdust” called frass. The larvae feeding on the interior of the wood create the frass. The holes are caused by the adults chewing through the wood’s surface after metamorphosis to emerge from inside the wood and mate.
Where to Look for Infestation
The common furniture beetle infests:
- Wood furniture
- Damp wood in crawl spaces
- Wood flooring
- Wood siding and other moist areas of the home
How Do I get Rid of Furniture Beetles
Resolving wood damaging insect problems is challenging and involves many factors for success. First, correct identification is required. Identification rarely is simple and will depend on recognizing the appearance of the insect, plus knowing the age, species, and moisture content of the infested wood. Therefore, it is always wise to seek the advice and recommendations of an experienced pest management professional rather than employ self-help or DIY measures.
Behavior, Diet & Habits
In many parts of the U.S. and international locations, the common furniture beetle is called the woodworm. These beetles go through complete metamorphosis, meaning this insect has an egg, larval (worm-like) pupal, and adult stage. Its life cycle is completed in about one to three years, depending on environmental conditions.
What Do They Eat?
Adults do not consume wood, while in fact, it is the larval stage that does the damage to wood when eating.
Where Do They Live?
Furniture beetles infest both seasoned hardwoods and softwoods that are generally 10 years or older.
