Woodworm Infestation And Treatment Products

Woodworm Infestation and Treatment Products: Everything You Need to Know


Since wood is rich in cellulose and other essentials, it is a common food source for fungi and wood-loving insects. Wood plays a vital role in an insect’s life. Not only does it provide food but also a strong and viable home. But, some insects cause massive destruction to wooden structures across America. 

There are different species of wood-loving insects, some are helpful to the wood life, and some are causing serious damage. Woodworm is one example of a wood-destroying pest. Let’s dive in and find out more about woodworm infestation and prevention. 

What is Woodworm?

Wood Boring Beetles lay their eggs in cracks and crevices of wood. When the larvae get hatched, they eat through the wood, creating tunnels and tiny holes. Woodworms consume cellulose and wood fibers to survive.

Woodworms are small, measuring just about 6mm in length. Their rigid body makes it easier for them to propel forward in wood. They can live in wood unnoticed for 3 to 5 years, and then when they reach adulthood, they leave their burrows searching for a mate.

What Causes Woodworm Infestation?

Just like any other insects, woodworms are attracted to moisture. Moisture is a key to their survival. Wood with a high moisture content is soft, making it easier to bore into, eat, and digest. Wood with 30 percent moisture content is an ideal paradise for woodworms. 

Untreated wood is another major cause of woodworm infestation. The lack of wood preservatives or a sealant can attract bugs and beetles to lay their eggs. They can easily penetrate your wood and cause further damage if left unchecked. Common beetles usually prefer the month of April to September to lay their eggs.

How to Prevent Woodworm Infestation

Woodworm infestation can be prevented easily. Some methods can prevent the infestation as early as possible. They seldom attack dry wood, so most infestations happen on outside furniture and wooden structures that are constantly exposed to water. 

Keep Wood Dry

Damp wood is a perfect place for female beetles to lay their eggs. Since moisture is available, the larvae can easily bore themselves into the wood. It is easier for them to chew on the wood and create passageways. 

Keep your home ventilated and Heated

A well-ventilated house reduces moisture build-up. Make sure that there is enough air circulation to keep your wooden dry. Additionally, heating your room at the right temperature can minimize wood saturation and keep your wood moist free.

Use Varnish to seal the wood

If you have untreated wood, use Varnish as a sealant while keeping your furniture nice and shiny. Varnish can prevent larvae from munching your wood. It serves as a protective layer to your wooden structure and furniture.

Removing infected wood

Removing or replacing infected wood can stop the spread of the infestation. Woodworm infestation is like a virus; they can transfer from one wood to another. If your furniture or timber is infested, replace it immediately to lessen further damage. 

Woodworm Treatment

Treating your wood with a woodworm treatment is the most effective way to prevent infestation. Permethrin is a chemical solution designed to kill woodworm and treat wood. Most experts use this insecticide to eradicate wood-boring insects and protect the wood from infestation. 


Whether dead or alive, wood is rich in nutrients, making it an ideal food source for insects. Termites and wood-boring beetles are just insects that love to eat cellulose. They cause serious wood damage and especially to our property. Luckily, there are step-by-step guides and chemical treatments to eliminate them. 

If a block of wood is infested, most homeowners throw away the affected wood, but there are creative ways to revamp your wood. You can create new furniture or use it for a new project. Plus, reusing your wood is environmentally friendly and cheap.
