Old House Borer, scientifically known as Hylotrupes Bajulus, is a notorious wood-boring beetle that can cause significant damage to your home. If you own an old house or are planning to buy one, understanding the treatment options available for Old House Borer is crucial to protect your property. In this article, we will discuss various tips and techniques for effective control of Old House Borer infestations.

Identifying Old House Borer Infestations

Before diving into the treatment methods, it is vital to identify whether your house is infested with Old House Borer. Look for signs such as small round holes in wooden surfaces, piles of fine sawdust known as frass, or hollow-sounding wood. If you spot these indicators, it’s time to take action.

Preventive Measures

Prevention is always better than cure. To minimize the risk of Old House Borer infestations, ensure that the wood used in your home is properly seasoned and treated. Avoid using damp or partially decayed wood, as it attracts these pests. Regularly inspect and maintain the wooden structures in your house to detect any signs of infestation at an early stage.

Chemical Treatments

When it comes to treating Old House Borer infestations, chemical treatments are often the most effective option. Borate-based products, such as borax, can be used to treat the affected wood. These products penetrate the wood and kill the larvae, preventing further damage. It is essential to follow the instructions provided by the manufacturer and wear protective gear while applying chemical treatments.

Heat Treatment

Another effective method for dealing with Old House Borer is heat treatment. This involves subjecting the infested wood to temperatures above 130°F (54°C) for a specific duration. The heat kills the larvae and eliminates the infestation. However, this treatment option requires professional expertise and specialized equipment.

Freezing Treatment

Freezing treatment is an alternative to heat treatment and involves subjecting the infested wood to sub-zero temperatures. This method is particularly useful for smaller wooden items that can be easily placed in a freezer. However, it may not be suitable for treating infestations in larger structural elements of your home.


In severe cases of Old House Borer infestations, fumigation may be necessary. This treatment option involves sealing the infested area and introducing a fumigant gas that kills the pests. Fumigation should only be carried out by licensed professionals due to the health risks associated with the chemicals used.

Replacing Infested Wood

For extensively damaged wooden structures, replacing the infested wood may be the best solution. This ensures complete removal of the pests and prevents further spread. When replacing wood, make sure to use properly treated and seasoned lumber to minimize the risk of future infestations.

Regular Inspections and Monitoring

Even after treating Old House Borer infestations, it is crucial to regularly inspect and monitor your home for any signs of reinfestation. Implement preventive measures, such as sealing cracks and crevices, to reduce the chances of a recurrent infestation.


Old House Borer treatment requires a combination of preventive measures and effective control techniques. Identifying the signs of infestation and choosing the appropriate treatment method are essential for protecting your property. Consult with professionals experienced in dealing with wood-boring pests to ensure the successful eradication of Old House Borer and the long-term preservation of your home.
