Wood-boring beetles are highly destructive pests that can cause extensive damage to homes and structures by tunneling through wood. Unlike surface pests, these beetles spend much of their life cycle hidden inside wooden materials, feeding and developing unnoticed for months or even years. Common species include powderpost beetles, deathwatch beetles, and old house borers, all of which can weaken wooden structures over time.
The most damaging stage of a wood-boring beetle is the larval stage. Larvae tunnel deep within wood, feeding continuously as they grow. This internal feeding gradually reduces wood to a powder-like material, compromising its strength and stability. Because the damage occurs from the inside out, infestations often go undetected until visible signs—such as exit holes or fine wood dust—appear.
Wood-boring beetles can infest structural lumber, floor joists, beams, subfloors, furniture, and decorative woodwork. Over time, repeated infestations can severely weaken load-bearing components, leading to sagging floors, cracked walls, and structural instability.
As beetles continue to emerge and reproduce, infestations can spread to new areas of the home. In older or moisture-prone structures, damage may progress more rapidly, increasing repair costs and long-term risks. Left untreated, wood-boring beetle damage can significantly reduce property value and create expensive restoration needs.
Ignoring a wood-boring beetle infestation allows damage to worsen and spread. These pests will not leave on their own, and surface-level treatments are often ineffective at reaching larvae hidden deep within the wood. Early professional treatment is the most effective way to stop active infestations and prevent further destruction.
Professional pest control treatments are designed to penetrate infested wood, eliminate beetles at all life stages, and protect wood from future infestations. Treating the problem early helps homeowners avoid extensive structural repairs and ensures the long-term safety of the home.
Effective wood-boring beetle control requires proper identification of the species, assessment of damage, and the use of specialized treatment methods. Professional inspections help determine the extent of the infestation and the most appropriate course of action.
Investing in professional treatment not only eliminates current beetle activity but also provides preventative protection for your home. With expert care and ongoing monitoring, homeowners can protect their property from hidden damage and costly repairs.


Wood-boring beetle infestations require targeted treatment strategies because the most destructive stage of the beetle’s life cycle occurs deep inside wood. Effective control depends on proper identification of the beetle species, the extent of infestation, moisture conditions, and the type of wood involved. Professional inspections are critical to determine the most appropriate treatment method.
Surface and penetrating wood treatments are commonly used for active wood-boring beetle infestations. These treatments involve applying professional-grade insecticides directly to affected wood surfaces. Penetrating formulations are designed to soak into the wood, reaching beetle larvae hidden beneath the surface.
This method is effective for accessible structural components such as beams, joists, and exposed framing. It also provides residual protection that helps prevent reinfestation. Surface treatments are often combined with moisture control measures to improve long-term results.
Injection treatments are used when beetle activity is deep within thick or enclosed wood. Small access points are drilled into infested areas, allowing insecticides to be injected directly into beetle galleries. This ensures that larvae and developing beetles are exposed to the treatment at their source.
Injection treatments are especially effective for localized infestations and structural elements that cannot be removed or replaced. Proper application requires professional tools and expertise to ensure thorough coverage without unnecessary damage to the structure.
In cases of widespread or severe infestations, whole-structure treatments may be recommended. Fumigation allows treatment agents to penetrate all wood within the structure, eliminating beetles at every life stage, including eggs, larvae, and adults.
This approach is often chosen when infestations are extensive or when beetle activity is suspected in multiple inaccessible areas. While highly effective, whole-structure treatments require professional planning and strict safety procedures.
When damage is severe, treatment alone may not be enough. Damaged wood may need to be removed and replaced to restore structural integrity. This step is often combined with insecticide treatments to protect surrounding wood and prevent future infestations.
Professional inspections help determine whether replacement is necessary and ensure that new materials are protected against beetle activity.
Preventative treatments play an important role in protecting homes from future wood-boring beetle infestations. These may include treating vulnerable wood, reducing moisture levels, sealing entry points, and scheduling routine inspections.
Ongoing monitoring and maintenance help detect early signs of beetle activity and prevent costly damage before it begins.
There is no single solution for every wood-boring beetle infestation. The most effective treatment plan is customized based on the structure, beetle species, and severity of damage. Professional pest control experts evaluate these factors and implement a comprehensive strategy to provide lasting protection.
