How can you enhance treatment effectiveness for white grubs?

Enhancing treatment effectiveness for white grubs can be significantly achieved by watering before treatment application. This practice serves multiple purposes: it ensures that the soil is moist, which can improve the penetration and effectiveness of the treatment, whether it is a pesticide or a biological control agent. Moisture in the soil can help the active ingredients reach the target area more efficiently and maximize their impact on the white grubs residing in the soil.

In contrast, treatments applied during winter or only when adults are active may not target the grubs effectively, as their life cycle stages vary throughout the year, and the most vulnerable life stage may not coincide with those times. Additionally, skipping irrigation after treatment can hinder the active ingredients from being adequately absorbed into the soil, diminishing their overall efficacy. Hence, pre-treatment watering is a best practice for achieving optimal results in managing white grubs.
