What is the recommended method for treating carpenter bees?

Using dust is the recommended method for treating carpenter bees due to its effectiveness in reaching areas where these pests may reside or nest. Dust insecticides can be applied directly into the holes made by the carpenter bees, allowing the active ingredient to settle in the area where the bees are likely to come into contact with it. This method targets the bees effectively because the dust can linger in the site of infestation, increasing the chances of contact with the bees as they return to their nests.

Additionally, dust applications minimize the risk of pesticide exposure to non-target organisms, as they tend to remain localized compared to other application methods. It is particularly beneficial when treating small, hard-to-reach spaces, making it a suitable option for controlling carpenter bees, which typically nest in wood surfaces. Using the right type of dust specifically formulated for bees ensures optimal results while maintaining safety and efficacy.
