Sam is always so considerate and timely! He made sure we didn’t have any pets that needed to go out before treatment since they wouldn’t be able to for 2 hours while it dries! Would recommend him to anyone! We haven’t had a mouse since his first visit!

I was worried about having bed bugs which is why I wanted an inspection. I've apparently had an unexplained allergic reaction to something. Chris was professional, thorough and pleasant. He reassured me that there was no infestation. The peace of mind Chris provided was worth the time and money. Thank you.

We having been using 603 Pest for over a year now. Decided to do the quarterly maintenance plan. They automatically schedule the appointment every 3 months but changing it is no big deal if needed. We also did the monthly mosquitoe/tick spraying last summer. Every single person that has come for the services has been super nice, they explain what they are doing, and they make sure to ask if we have any additional questions or concerns. Super happy with the effectiveness of services and the excellent customer service.

Absolutely phenomenal service. From the office to the technician, my wife and I were very impressed. We had a field mouse problem in our basement that I couldn't quite get to the bottom of, and I'm so glad I finally called 603 Pest and handed it off to them. After their first visit I noticed a complete stop in activity (after catching one leftover mouse that was already likely in our home). I set a trap again in our highest-traffic space and never caught another. Problem solved.

Chris came out for mice and to set traps, closed up places of entry, and sprayed for ants. He was prompt, polite, and did a great job of explaining what he was doing and what we should look for in the future. Within two days we had caught 6 mice. Dan came out for a follow up two weeks later to set more traps. Dan was also great and happy to answer questions and educate us on rodents. We are very happy with the results. Price was higher than I had initially hoped, but it was in-line with other pest control companies that I had looked into, so it seems like a fair market price. Will call again if we have more pest issues in the future.

They had to rearrange some things to be able to help us, they called back within minutes and had someone out to us in about an hour. Dan came and was so thorough. treated the issue effectively, and was even nice enough to knock another nest on our porch that he noticed before he left. Highly recommend!

Over the past few years, my wife and I have experienced recurring problems with yellow jackets and wasps taking up residence on our property. After receiving some painful stings, we contacted 603 Pest Control Services for help. They scheduled an appointment the next day. Sam, the technician assigned, arrived on time, was very personable, knowledgeable and professional during the service. He explained what the service entailed, did a complete inspection around our home, kept us apprised as the work progressed, eliminated a fist-sized wasp nest under our deck steps, and treated other areas around our home to prevent further nesting. Jen and Niki from the office staff were very helpful scheduling the service as well as answering our many questions. Their service fees are reasonable and their technicians are trained and properly equipped to perform the service. We’ve used other pest control services in the past but none were as responsive as 603 Pest Services. We were very impressed with the service received. Thank you Sam, Jen and Niki!!!

    Ant Spraying

    Ants are common pests in New Hampshire – as is the need for professional quality carpenter ant treatment and treatment for NH ant species.  It’s vital to retain ant exterminator services from an experienced ant removal specialist such as 603 Pest Control.

    As your local ant removal experts, we act as both an ant exterminator and ant pest control strategist.  Not only do we destroy the ants you can see!  We ALSO know that the best way to get rid of ants is by doing a thorough pest inspection and destroying ant nests. 

    Ant types and appearances vary. Most ants are a black, brown, or reddish color, and have a head, thorax and abdomen, although the thorax and abdomen are not always obvious. 

    Spraying for Ants: Treatments and Solutions

    When any spraying, a common and effective ant treatment, (especially carpenter ant treatments), it is critical to locate and destroy the nest. 603 Pest Control experts treat homes and businesses for ants seasonally using EPA registered and labeled products.  

    Our customers typically protect their properties with our quarterly pest control service, since most properties encounter more than one type of pest, so it’s more cost effective to ensure protection on a quarterly basis, instead of waiting until there’s an infestation.

    It’s wise to approach any unfamiliar pest with care, and consult with an experienced ant exterminator regarding your options for ant pest control.  If you need help with identifying types of ants and the best ant removal solution for your home or business, contact 603 Pest a call for a free consultation.

    • Carpenter ants vary in size, color, and function: Worker ants are small black quarter inch to three-quarters of an inch long.  Swarmer ants have wings, and males and females swarm by the hundreds in the springtime. Carpenter ants are typically black, but can have bits of red, making them appear two-toned.  Carpenter ants have pinched waists, one node, and powerful mandibles to bite or sting. Spraying for carpenter ants requires finding and destroying the nest to prevent their return.
    • Pavement Ants are very small – about one eighth to one sixteenth of an inch long, and are mostly brown with black accents. They move slowly, so you should be able to see them long enough to spot the parallel lines on the head and thorax. 
    • Odorous house ants are all the same size – one twelfth to an eighth of an inch long – and are brownish black. This ant species is named for the off-putting odor it emits when crushed. 

    Each of these ant types exists year-round. They are most active from May through September, and swarm during their breeding season, which is May and June in New Hampshire and the northeast.

    How to Identify Ant ActivityAround Your Home or Property

    Some practical characteristics and cues to identify ant activity include:

    Carpenter Ants:

    • Build their nests by excavating wood and creating clean, smooth pathway networks. They don’t eat the wood; they burrow in it, sometimes causing severe structural damage to your home or building. 
    • Prefer to nest in wood damaged by water – such as support beams, wood decks, and roofing. supports. Frass is the sawdust that carpenter ants pile up from burrowing into wood.  (Termites use the frass as a food source, but carpenter ants don’t.) 
    • Will travel 100 yards or more for food. They eat anything sweet, and are attracted to moisture. 
    • Have a metabolism that slows down in the winter, when they don’t travel far from their nest. But in the Spring when temperatures rise, carpenter ants travel for water or moisture.  
    • Can be found around bathrooms, sinks, kitchen counters, plumbing areas, basement sill plates, and trailing into the home from window sills, window sill plates, front stoop areas, and back decks. 
    • Are black and very large. The reproductive carpenter ants have wings. When they swarm, the wings of a carpenter ant are dark and tinted in color – versus the wings of a termite which are clear. Carpenter and termite seasons intertwine.  Carpenter ants have a pinched waist, while termites have a flat waist.

    Pavement Ants:

    • Need moisture to survive. They constantly search for sugar and protein as they forage for food inside and outside of homes and offices.
    • Prefer to nest in walls, under floors, and in insulation. They also nest patios and driveways, under rocks and cracks in the pavement.

    Odorous House Ants:

    • Build nests indoors or outdoors.  They move in trails along floors, cabinets, countertops, walls, and around pet food dishes or other food sources. 
    • Forage for sweets and honeydew (which is a sweet, sticky secretion produced by other insects).  Some varieties are active during the day, while others are active at night. Their colonies are very large with many active queens served by scores of worker ants.

    Disease and Property Damage that Ants Can Cause

    Ants are not unsanitary pests nor do they carry disease, but some types of ants can bite and sting people and their pets.

    Carpenter ants can cause incredible amounts of damage to major support elements of homes and structures. They can cause damage behind chimney walls, and all over a home or building, from attic to basement. 

    Pavement ants cause property damage by tunneling underneath the pavement and weakening or collapsing it. They also do cause damage underneath patios.  Pavement ants are not a wood destroying pest.
