"My review is similar to the other strong reviews. I received a text from Bob the morning after I posted my request for help. Bob arrived at my home promptly, and talked with me about the different options regarding rodent control. His two sons came this morning, and were polite, knowledgeable and did the remediation described by Bob. They closed entry points for rodents and answered all of my questions about the materials they were using.Now I need to wait to determine if the corrective action taken will solve the problem."

"Dave was excellent. He was professional, honest and thorough. I thought I may have squirrels in the house because I heard scratching above a ceiling and saw a squirrel climbing my chimney with acorns in it's mouth.  
Dave inspected all the outside areas of my house and looked in my attic. He found no evidence of squirrels or bats or anything else (other than a few mice that I can take care of).
He screened off my two gable vents and recommended securing a couple of other entry prone areas which I can do.
I highly recommend Colonial Pest Control.

FAQs for rodent pest control service projects in Merrimack, NH

Rodent exclusion seals every gap, vent, and crack that rodents use to sneak inside your home. Most homeowners pay an average of $200 to $600 for this add-on. By blocking entry points, you create a long-term barrier that cuts down on repeat infestations and helps protect both your family and your property.

Pros start with an inspection, then place tamper-resistant bait stations and traps in high-traffic spots. They’ll also seal entry points and clean droppings to reduce health risks. Follow-up visits confirm that the plan worked and that no new rodents have moved in. This step-by-step approach removes the current infestation and helps keep your home rodent-free going forward.

A trained pest-control pro can pinpoint hidden access points using a flashlight, thermal imaging, and plenty of crawl-space sleuthing. During an inspection, the specialist maps every gap, vent, or pipe run that rats use, then explains how to seal each one. This detailed report lets you tackle the weak spots immediately and dramatically lowers the odds of another infestation.

Rodent prevention starts with managing food and entry points. Store pantry items in airtight containers, take out trash promptly, and keep pet food sealed. Outside, trim vegetation and stack firewood away from the house. Inside, seal gaps with steel wool or hardware cloth. A tidy yard and a buttoned-up home give rats and mice few reasons—or routes—to move in.

For wall or attic nests, pros place snap traps or CO2-powered units in the exact runways rats use, then return to remove carcasses and reset as needed. Poison is risky indoors because rats may die in hidden spots, creating odors or health issues, so most technicians avoid it. Once trapping is complete, they’ll seal entry points and clean droppings to finish the job.

Plan on several weeks, especially for larger infestations. Your pro will set traps, return every few days to collect rats, and adjust placement until activity stops. Final visits include sealing access points and sanitizing affected areas. Timelines vary, but most homes are rat-free after two to four follow-ups. Prompt scheduling and good sanitation can shorten the process.
