The first warm evening of May on a deck in Portsmouth or Exeter tends to remind a homeowner about ankles before it reminds them about anything else. The sun has not dropped yet. The grill smoke from a neighbor two yards over is still curling around the fence. Nobody has even sat down. And the first slow circle of a mosquito around an exposed calf signals that the bugs have been outside for weeks while the family was still inside. Mosquito Pros NH has served Rockingham, Hillsborough, Merrimack, Strafford, Belknap, Carroll, and Grafton counties since 2010, and the early-May barrier visit is one of the more common starting points before Memorial Day. The first warm evening always feels like a surprise to the homeowner. It rarely is.
This is a plain language checklist for the walk you do before you book a barrier visit. You do not need to know the difference between Platinum, Gold, Silver, and Peak before you read it. You only need to look at your yard with honest eyes for ten minutes and write down what you find. When you are ready, send the notes through contact or call 603-778-1471 and we will translate them into a real visit plan. Pair this read with our mosquito control and tick control pages for how the programs themselves work.
Walk the still air corners first
Mosquitoes are weak fliers. They do not fight wind. They look for pockets where air goes still and where carbon dioxide gives away a warm-blooded creature. On a typical southern New Hampshire lot those pockets are exactly the places people gather. Roof overhangs above a back deck. The corner where a tall planter meets the railing. The narrow stretch of grass between the side of the house and the first row of foundation shrubs. The fence return where the privacy panel meets the neighbor garage. Walk those corners with your phone and take a photo at each one. Two minutes of walking. Five photos. That short packet, sent through contact, tells a technician more than ten paragraphs of description ever could.
Tip the standing water you can reach safely this week
The next bit of the checklist costs nothing. After the next rain, walk the yard with a bucket. Tip plant saucers under the basil and the herb garden. Empty wheelbarrows. Flip tarps that have started to cup water in the middle. Take a look at the kids' sandbox if it has a cover that pools. Peek at the gutters if you can do so safely from a ladder you already trust, but only if the ladder is one you already trust. The point is not heroics. The point is that the easiest mosquito breeding sites refill in three days, and the ones you remove yourself keep the larvicide conversation focused on the harder ones your technician finds.
Read the play lawn before the swing set returns
The play lawn is the strip of grass between the deck and the wood line where kids run barefoot in July. In early May, walk that strip slowly and notice three things. Where does the grass meet brush in a sharp line versus a gradual taper. Where do the dogs cut the corner every evening on the way to the back fence. Where did the snow plow leave a low spot that holds standing water for a few days after rain. Each of those three points matters. The first is where ticks sit on tall grass tips waiting for an ankle. The second is where pets bring ticks back to the patio. The third is where mosquito larvae develop in the puddle the lawn has not drained since March.
Honest notes beat perfect prose every time
We would rather read a five-bullet text message from you than a perfect paragraph copied from another mosquito company website. The notes that help us most look like *left fence corner has standing water two days after rain*, or *dog cuts through tall grass under the maple every evening*, or *we eat dinner on the deck Wednesday and Friday nights and never on Mondays*. That kind of detail tells us where to focus barrier work and when our visit should fit your real outdoor calendar. The schedule for Peak clients runs roughly every seventeen to twenty-four days from Memorial Day to Labor Day, but the visits themselves are calmer when we know the rhythm of how you actually use the yard.
Confirm your town before you assume drive time
We work from two offices. The Exeter office covers most of the Seacoast and the towns through Hampton, Portsmouth, Stratham, and the lower part of Rockingham County. The Gilford office handles the Lakes Region and reaches into Laconia, Wolfeboro, Meredith, and the towns along the lower Carroll County corridor. Confirm your town on service areas before you assume drive time. We are honest about coverage. Lebanon sits outside our service area despite many requests, and we would rather say so up front than book a visit we cannot deliver.
Tell us about Memorial weekend if it matters
If you host a crowd Saturday evening of Memorial weekend, tell us when you call. We can sequence the first treatment so the foliage and grass have dry time before the first guest arrives, and we can plan the next visit around the rhythm of guest weekends rather than against it. The events page covers how we think about timing when the calendar drives the work rather than the weather. Weddings, fundraisers, and neighborhood nights are the canonical events we plan around. School-end gatherings are starting to show up more on the same list every May.
A closing note about expectations
We are not promising zero insects on the first warm night of the year. We are promising that licensed, insured technicians will treat the yard with the same honest care we would apply to our own families' decks. Mosquito Pros NH has been doing exactly that since 2010, and we still answer the phone in plain language. Send your photos and your notes through contact or call 603-778-1471 when you are ready. The earlier in May the conversation starts, the calmer the rest of the season looks.
