What is the best method to treat pest issues on rainy days or during drizzling?

Dusting is considered the best method to treat pest issues on rainy days or during drizzling. This is primarily due to how dust treatments work and their effectiveness in adverse weather conditions. Dust formulations are less likely to be washed away by rain compared to liquid sprays or fogging solutions, allowing for localized treatment in areas where pests may reside.

When it rains, moisture can dilute or wash away spray treatments, reducing their efficacy and potentially leading to ineffective pest control. Dusting, on the other hand, adheres well to surfaces and can remain effective even in damp conditions, thereby providing a continued barrier against pests.

Additionally, dust can penetrate into crevices and voids where pests often hide, ensuring comprehensive coverage even during unfavorable weather. This makes dusting a more practical choice for maintaining control over pest populations regardless of rain.

While trapping can be effective for monitoring and reducing pest populations, it does not provide immediate treatment to the existing issues in the same way dusting does, especially on rainy days.
