While we limit the use of chemicals as much as we possibly can, there are times when they must be used to help limit the damage to a problem. However, we don't use sprays to continually mask the symptom of an underlying problem. We work with nature to correct the underlying problem if possible. This helps up reduce adding chemicals to the environment that don't always work well with nature.
For the health of children, pets and our environment we don't use restricted pesticides. When pesticides are labeled restricted it is because they have shown to pose a direct hazard to human health and or the environment.
