Mid-May on the East End is when warm, damp air starts to stick around. Siding, mulch beds, and screen doors stay moist longer than they did in April. At the same time, beach weekends pick up: guests, wet towels, and coolers moving through the same door every few days.
That combination often brings ant trails along cool foundation walls and ticks along wood edges you have not walked since early spring. They are different problems with different fixes. This article helps you tell them apart before you call us about the wrong pest.
If you also see sawdust under a window, read carpenter ants when windows stay open. For biting pests in general, see our spring tick and mosquito guide. Service details live on ant control and tick and mosquito control.
How humidity affects ants on the outside of the house
Salt air does not create ants by itself. It does leave a thin film on paint and stone that ants sometimes follow as they search for food and water.
After a cool foggy night, north facing walls in Southampton and East Hampton can stay damp even when the deck feels dry. Ants often show up along those cool bands while you are busy with sand in the entryway.
Walk the foundation on a dry afternoon. Note where downspout splash hits mulch. A wall that stays dark two days after rain is a moisture clue. A trail that only appears when trash sits out overnight is a sanitation clue. Photos taken at the same time of day for three days help more than guessing at midnight.
Kitchen ants versus ants along the garage slab
Odorous house ants and pavement ants look similar from a distance. Lines near sinks, pet bowls, and outdoor grills usually need kitchen cleanup plus professional ant control. Lines along the garage slab in Bridgehampton may be a perimeter issue instead.
Winged ants at a slider are not always termites. See flying ants versus termites before you panic. Carpenter ants often leave sawdust near damp trim; our post on carpenter ant sawdust at windows explains that pattern.
Tick edges before guests use the whole yard
Ticks live where grass meets woods, stone walls, and tall hedges. Unmowed strips in Sag Harbor and Greenport stay cooler and damper than open lawn, which is why people pick up ticks on the way to a beach path.
Walk those edges before you set up chairs for the weekend. Our Memorial week tick checklist fits when play areas sit near tall grass. Chiggers versus lone star ticks clears up a common mix-up when itchy bites show up after yard time.
If mosquitoes at dusk are the bigger complaint, read mosquitoes at dusk on the deck. Our yard edge quiz helps when you are not sure which outdoor issue to tackle first.
Beach weekends, dogs, and what to expect
Guests bring dogs from other towns. Kids cut through ivy. Coolers sit on the same patch of grass beside a hedge. That does not mean your April program failed. It means more people and pets are using the yard before you have finished spring edge work.
Keep trash sealed, rinse recycling outside, and hang dish towels where they can dry instead of draping them on foundation stone.
Pantry and kitchen issues in second homes
Humidity softens stored food and guests open every cabinet. Pantry moths in second homes and our April pantry moth notes cover that side of the kitchen.
If you see cockroaches in Hamptons kitchens as well as ants, mention both when you contact us so we can plan the right indoor work.
When to call
Call when ant trails cross food prep areas every day, when sawdust keeps returning under a window, or when ticks show up on several people after short time in the yard. Send photos of trails, yard edges, and the time of day you notice activity through contact.
