If rain is a factor before we arrive we will call our clients to ask what they would like to do as this is the client’s investment. We will explain that rain will only affect the outcome of the treatment if it is raining whilst we are applying the pesticide/s but we do not apply pesticide/s when it is raining at the time of treatment. If it looks like rain or the rain has stopped then we can apply the pesticide/s as our pesticide/s require a short time to dry & the pesticide/s starts working immediately when applied.
