Our quarterly service plan is essential to maintain a pest free home year round. Our organically derived product has a residual of about 60-90 days. Right as the product is naturally being broken down by UV Rays and rain/sprinkler system exposure, we are right back out to reapply and give you that year round pest protection you are looking for. The service area includes up to 10-12 feet from the foundation of your home, giving you a pest free patio to grill on without any uninvited guests and a large amount of play area in the yard for the family to enjoy. Our quarterly service plan comes with a full guarantee, if you have a common pest problem between services, we come back and take care of the issue at no extra charge!
