When fumigating for beetles in hardwood flooring, what is the recommended rate?

The recommended rate for fumigating for beetles in hardwood flooring is indeed 10 times the normal rate for Drywood termites and certain wood-boring beetles. This elevated dosage is necessary because beetle infestations can be quite resistant to standard treatments due to the characteristics of hardwood. The increased concentration helps ensure that the fumigant thoroughly penetrates the wood, effectively reaching and eliminating the pests that may be nested deep within the flooring.

It is crucial to understand that different types of wood pests may require different approaches and concentrations. In this case, the specific mention of Drywoods indicates a targeted approach toward a known problematic pest in hardwoods. The other options are either not sufficient in dosage or misrepresent the required methods for effective treatment.
