Q: Will the spray get on my house/deck/car?
A: The technician will walk around the tree, always spraying towards the center of the tree. Anything (such as a car or patio furniture) that can be moved from the immediate area should be moved ahead of time. Anything that can’t be moved, but can be covered, will be covered with a tarp (however, some dripping may occur once the tarp is removed). For trees overhanging buildings or decks, it is likely that some residue will be left on those objects. The residue is not harmful, and will break down within 6-8 weeks. Cleaning with soap and water can speed the process.
Q: Will the spray harm my children or my dog?
A: People and pets may enter a treated area after the spray has dried. Drying time depends on temperature and humidity, but usually 1-3 hours is adequate drying time.
Q: Will the spray harm my other landscape plants?
A: Some plants, especially some annuals, may be sensitive to some of the chemicals we use. Most plants will tolerate any chemical we use. Check with your Consulting Arborist to see if any of your plants need to be moved or covered.
Q: It rained this afternoon. Will the spray still be effective?
A: We use a spreader-sticker additive in all of our spray applications. As the liquid dries, the spreader-sticker makes sure the chemical stays put on the surface it was applied to. There is no need to reapply the spray as long as it had a chance to dry. We monitor the weather conditions, so if it rains shortly after our application, we will come back for a re-application.
Q: The technician was here only a few minutes. Did they do a good enough job?
A: It doesn’t take long to do the application. Mixing the chemical in the tank is often done before they arrive at your home. Our hoses spray at a high pressure, so circling the tree once is enough to hit the surface of all the leaves. Sometimes it takes more time to walk to the tree than it does to spray the tree! When in doubt, call us – your Consulting Arborist can check your tree for residue to insure that your tree was properly covered.
