Powderpost beetles can be difficult to remove from hardwood floors with a single application of this pesticide. Due to the large variation in life cycles of wood-boring powderpost beetles, more than one application may be necessary. You may also need to repeat the application if you notice new holes after the first treatment. This may indicate that some larvae must still be present inside the wood.

It is important to note as well that the solution may not penetrate properly if the floor is extremely dry. There is a possibility that you will miss a large number of larvae and adults.

The house will not be evacuated during treatment. This means you can complete the task at any time. You will only need to temporarily relocate if you use professional fumigation services.

Use Fumigation

Pest control professionals are required to carry out the fumigation. The pesticides or chemicals that are used to remove powderpost beetles from hardwood floors should not leave any residue. The last thing you would want is for your family or pets to become ill due to pesticide residues. Pesticide residues can cause serious health problems.
