I am just wondering if the rain will wash the residual powder away? I live in Washington State and it rains alot up here. Would I need to re-treat the perimeter after it rains? Can you recommend a substitute product for ant control that is better suited for a wet climate that is also kid-safe.
Eco PCO WP-X will hold up to rain very well as will most of the products that we sell. It is actually not rain that is the real threat. UV light is what breaks pesticides down the most. You should apply the product when it is not raining and also hopefully when it is not going to rain for at least a few hours so it has time to dry. Once it has had at least a few hours to dry and adhere to the surface that you applied it on it should provide a good 30 to 45 days of residual protection, rain or shine. It is usually a good idea to re-apply every 30 to 60 days during the summer to get the best results.
