The best way to control pests is to spray a few times in the spring before the pests become pests. Regular spraying of the entire landscape throughout the spring months will help keep the pest problem manageable and can potentially diminish them enough to not even notice their existence the rest of the summer.

Depending on the type of pesticide, you will need to determine frequency. For example, organic pesticides can and should be sprayed more often, even weekly.  For heavy infestations we spray daily until under control.

Chemical pesticides can endanger the life the plant, so spraying should be no more frequently than recommended on the bottle. Most suggest every two weeks, some say monthly. Just remember, prevention is the best form of control.
