About GSC Pest Management

Arnold Gilmore

Company Description

GSC Pest Management was founded in 1964 by Arnold Gilmore of Rochester, NH.  Back then it truly was a sole proprietorship because the person that took your requests for service was the same person that came to your home.  Over the next 25 years GSC grew steadily and established a reputation for serving their customers with skill and integrity.

Arnold retired in 1990 and his son in law Tom Aspinwall became the new owner and manager. He is continuing the tradition started by Arnold of bringing service to a higher level for a commercial and residential base of more than 5,000 customers. 

 

Today GSC has the distinction of welcoming in the third generation of pest control professionals with both of Tom’s son’s joining the business. Tyler Aspinwall is the Head Technician and Operations Manager, and Torey Aspinwall is the Service Manager. They both joined the company full time after graduating from UNH in 2017, and together they are continuing that family tradition.

Pest Control & Prevention Services

GSC Pest Management provides a variety of pest control and prevention services to residents and businesses throughout Southern New Hampshire and Maine.

Yard Treatments

Yard treatments are very effective at controlling mosquitos and ticks that rest in grass and green
growth around a structure and rec areas. Contact us about getting on a monthly mosquito control
program or about spring and fall tick control.

 Barrier Treatments

A treatment around the perimeter of your home; 3 ft up the foundation and 3ft out will provide 2-3 months protection against invasive insects, such as ants, spiders, and yellow jackets, and more. Recommended in Spring and Fall for a full year of protection. 

Spot Treatment

When it comes to the control for minor pest activity, a full service
program or treatment of the entire structure may not be necessary or
warranted. Spot treatments are a one time localized application for the
control of a specific pest.

Termite Treatments

GSC provides both full liquid termiticide treatments and termite baiting systems. Our treatment programs provide a 15 year service agreement in case of termite reemergence with an annual termite inspection.

Rodent Control 

GSC provides services for the control of commensal rodents, which are
rats and mice. Our programs are designed around the needs
of each specific property in order to meet our customers' needs.  Ask us about our rodent flex and seasonal programs.

Wasp and Hornet Control

Wasps and hornets build new nests every spring and use them for one season. The location of the nest
can be problematic when in close proximity to human activity. Depending on species, nests may be in a tree, under an eve, in the ground, or in a wall void. Rely on GSC for safe and effective treatment options.
