Are generally set up every other month for the duration of the spring/summer season. Most customers take on these packages due to bee/wasps problems, but we can treat for up to 35 different outdoor pests with the materials we use. The services are set up on an every other month basis due to the fact that the materials we use, tend to break down around the 60-75 day range. We can arrange the services however the customer wants us to! The program is extremely effective if started in April or May, but can also be very effective at eradicating yellow jacket activity in months after June!
