Jean from Heppner, Oregon writes,
Can you use your sprinklers after using Onslaught and if so how much time before using them?
I use my sprinklers in the evening to water my junipers where I am spraying for yellow jackets -If i spray in the morning is it OK to do my regular watering or will the onslaught wash off?
You should allow the areas that were treated with Onslaught to dry for 24 hours before turning on the sprinklers. This will allow the product to bond to the surface so it will not be washed away.
