You sit in the same chair after dinner every warm night. By the third evening in a row, your ankles are covered in bites even though the middle of the lawn looked fine at noon. That pattern is common on New Hampshire yards, and it usually has a simple explanation.
Mosquitoes rest in shady, still air during the day. At dusk they move toward people, pets, and grill smoke. If your favorite chair sits near foundation shrubs, a fence corner, or under a roof overhang, you are in the path they already use every evening.
Why one spot gets hit harder than the rest of the yard
Open lawn in full sun often has fewer resting mosquitoes than the band along your house, deck railing, or privacy fence. That band stays cooler and holds moisture longer. Mosquitoes gather there, then fly a short distance to where you sit.
Check these areas around your deck:
- Foundation plantings and mulch beds against the house
- The corner where two railings meet
- Planters with saucers that hold water after rain
- Low branches that hang over seating areas
- The first few feet of grass between the deck and the wood line
What you can do before calling for service
Empty plant saucers and bird baths after rain. Pull mulch back a few inches from siding so it dries faster. Trim low branches that touch the deck or fence. Run a fan on the seating area during dinner. Mosquitoes struggle in moving air.
These steps help, but they rarely solve the problem on their own once mosquitoes are established along the perimeter.
How Mosquito Pros NH treats the problem
Our barrier spray targets the areas where mosquitoes rest before they reach your chairs. A licensed technician treats shrubs, fence lines, and foundation plantings around the yard perimeter, then focuses on the spots where your family actually spends time: decks, fire pits, play areas, and pool edges.
Treatments are scheduled through the season so protection stays active between visits. You do not need to be home. We honk when we arrive and leave a door hanger when the yard is done.
When to schedule your first visit
If the same chair is bitey every night, do not wait until mid-summer. Starting barrier spray in late April or May, depending on your town, keeps populations down before they peak. We serve Rockingham, Hillsborough, Merrimack, Strafford, Belknap, Carroll, and Grafton counties from offices in Exeter and Gilford.
