This is an infuriating review to write, as I have been dealing with this mouse infestation and BC Exterminating since July 18 of 2025 and it is now January 16 of the following year with no solution. I spent a whopping $1,690.70 for BC Exterminating to clear our house of mice with a 60 day warranty that they would come and re-treat the house at the first sign of any droppings or mice. This warranty would start over from the most recent sign of mice. At first, they appeared diligent and competent
Quick, responsive, and professional service. After calling four other companies this morning to deal with a large hornets nest, BC Exterminating was the only one that didn’t transfer me around or suggest someone would “call me back” later (which they eventually did—two hours later). BC gave a clear, competitive price without pushing a monthly plan and had a technician at my house within two hours. Oswaldo and his tech were fast, friendly, and professional—especially thoughtful knowing we have k

Thank you !
Man I was up there visiting my Aunt and she had an appointment with Paramount to come out to the house for a service call. But anyway this dude Xander calls her up and gives her about a 10 minute heads up that he is almost there. He gets there and I'm just letting them do what they do, and when Xander came in and started talking to my Aunt Mary, you would think they were friends for the last 20 years. I live in North Carolina and it's common to see polite people but this was beyond being polite.
Tried others Senate was the best. Gas company dug up the sidewalk in front of several homes and it causes mice to invade our homes. I tried 2 other company they failed. Senate came in set up a schedule plan 👏 and cleared up the problem. It was affordable and I still have a quarterly plan and no critters and they're pet conscious. Keep your pets away from treated areas for a hour everything is good. You may have to pick and choose the workers. As in everything some may not be that passionate abo

I completely trust Oliver Clark from Terminix to ALWAYS deliver excellent service in providing me with the best protection from pests that is available. Oliver arrives on time every time and since I’ve been a Terminix customer for over 10 years I’ve never been disappointed in the service Oliver has provided me! I very much appreciate this customer experience created by using Terminix and Oliver and I look forward to many more such interactions going forward

Your positive review is the best compliment! Thank you for being a customer.
We have had Oliver taking care of our home for the last 20+ years. He is absolutely fantastic. Friendly, professional, always communicative, and thorough. If we ever have any issues that need additional “bug” treatments, he is always willing to come back, or discuss another plan to take care of the issue. We can’t imagine anyone else for our pest control other than Oliver. He is truly THE BEST. Ask for him!!!

“I rarely leave negative reviews, but my experience with Orkin’s mice control service was extremely disappointing. I was charged nearly $250, and what I received was something any homeowner could have done on their own. The technician placed a few standard traps, told me to buy spray foam from Home Depot, and left. No thorough inspection, no attempt to locate how or where the mice were entering. I followed their advice, applied foam behind the oven, and still kept seeing mice. When I called them”

“Do NOT do service with Terminix if you're in the Gaithersburg area. Their local office is AWFUL. I got an Exclusion service with them a few years ago for mice. Still would get mice once in a while. They finally said there was nothing more they could offer. So I cancelled them. I cancelled this service MONTHS ago and had to call twice to get this done. And now, they've sent me a notice saying I owe them payment for the Exclusion service that i NO LONGER HAVE. It doesn't even show up on my o”

“Lawn Doctor actually damaged my lawn. After 4 times treatments within the six months ( from Aug- Dec 2020 ( 4 times according to them actually only come three times, then to April 2021 one time without my permission), the weeds in my lawn were even worse than before that I had a picture to confirm.
