Our Approach

At Green Shield Pest Solutions in Southern Maine, we utilize integrated pest management (IPM), which is the use of all available tactics or strategies to control pests. The old days of spraying unnecessary chemicals and "exterminating" everything in sight are over. Our pest control service includes:

Identify the Pest

A licensed and trained service professional will arrive and assess your need for treatment by completing a full inspection of the exterior of the home.


This involves developing a management strategy beyond blindly spraying.


Detailed notes are taken each visit so family-friendly products can be applied safely to exactly the right locations.

Follow up and Prevention

In order to break pest life cycles, return visits in some fashion are important to prevent pests from returning.

Seasonal Protection

The most effective way to manage pests is seasonally. This is because products only last 90 days and are ineffective during egg and pupal stages of the pest life cycle. A visit from Green Shield will typically include the following each season. For a quick guide of which pests are covered with our standard plan, please see our pest library.

Exterior Perimeter Spray

On a first visit we will use products that bugs will take back to the nest. On subsequent visits, repellents work best to seal entry points. The foundation is ground zero for pests trying to get inside for moisture or food.

Windows and Doors

Besides the foundation, windows and doors are the second most likely place pests enter a home, or business, especially for fall pests like stink bugs. We use a variety of dusts which will not stain windows, but will stop invaders in their tracks.

Nest and Web Removal

We use a twenty foot pole with a giant brush attached to knock down wasp nests and spider webs. Not only does it make your home or business look cleaner, but it discourages future web/nest building and potential entry.

Granule Application

Instead of only treating the structure like most companies, we often apply granules to softer surfaces like lawns and flower beds when necessary. These release a product over time so bugs do not come close to your home. Many who experience ticks around their home also like us to apply granules along the wood line of their property.

Rodent Control

Mice become a significant pest in winter months, especially in garages and basements. Not only do we apply pet-friendly traps, but our best work involves applying steel wool and caulking in areas where they could be entering.

Interior Crack and Crevice Treatment

It's not always necessary, but when significant infestations occur such as carpenter ants, we are able to monitor and apply baits and gels to cracks and crevices to flush out pests from a common place, the inside of the wall cavity.

Ticks and Mosquitoes

With our consistent year-round rainfall, mosquitoes and ticks thrive in southern Maine. Due to living and reproducing in much different locations than standard household pests, ticks and mosquitoes require their own specific treatment. This typically involves coming monthly from April-September for best results. Green Shield Pest Solutions is well known for being thorough and using family and pet-friendly products to get them under control. For more information on ticks and mosquitoes, visit their section in the pest library here.

How we treat

One of our licensed technicians would inspect your property and use a mosquito fogging machine to apply a family-friendly product to your tree line or property line.

Where we treat

This is applied 10 ft high to target nesting sites in trees and also targets landscaping, thick foliage, and dense shrubs. Much of the yard is usually covered as well.

What to Expect

You can expect a 90% decrease at first with a gradual drop in effectiveness over the next 30 days. Green Shield typically treats monthly for this reason.

Why come seasonally and how does it work?

Contact Us

After contacting us, a representative will get back to you within 24 hours and evaluate what you have been experiencing. We will ask lots of questions and are great listeners. If necessary, a licensed technician will be scheduled to visit your home and we will ask you to be there for a brief two hour window.

First Visit

After treatment, you should see a dramatic improvement within 2-4 weeks. After this, our products will break down in 90 days with weather, and new eggs will hatch which we were not able to penetrate on our first visit. For tick/mosquito treatments, results are more immediate but wear off quicker.

Other Visits

After the first visit, we will return in 90 days to take care of all bugs which have hatched in the past 90 days. This will further reduce the pest population and is called "breaking the pest life cycle." Winter is especially important since this is when bugs are dormant and few in population. For tick/mosquito treatments, visits are monthly from April-September.

Free Reservicing

We guarantee all our work and don't expect you to blindly trust us. If your pest issues return, we will return to your home at no charge.
