Sand Gnats: The Lowcountry's Contribution to Your Reviews

Every region has a pest that visitors do not expect. In the Lowcountry it is the sand gnat, and it is the one thing about a Savannah porch that reliably surprises people who booked the porch specifically.

They matter to a rental because of when they show up. Spring and fall are their strongest periods, which is also when Savannah is at its most pleasant and your calendar is fullest. The guest who booked in April for the weather is the guest most likely to meet them.

Why the screen does not stop them

This is the part owners usually have not worked out. Standard window screen is around 20x20 mesh, which is sized for mosquitoes. Sand gnats and no-see-ums are considerably smaller and pass straight through it.

A screened porch therefore keeps out mosquitoes and lets in the thing people are actually complaining about. Finer mesh — the sort sold specifically for no-see-ums — closes the gap, at the cost of reduced airflow, which on a humid Lowcountry evening is a genuine trade-off rather than an obvious upgrade.

Worth knowing before you re-screen a porch in response to a review, because re-screening with the same mesh solves nothing.

What actually helps between guests

They breed in damp organic matter — leaf litter, damp mulch, standing water in a saucer under a plant pot, the gap where a downspout discharges next to a porch. Turnovers are when that gets found, because nobody else is looking at the corners of a porch.

Emptying anything holding water, clearing leaf debris from porch corners and the base of steps, and keeping mulch back from the house does more than any spray, because it removes where they come from rather than what is already flying.

A ceiling fan on a porch is the other genuinely effective measure. They are weak fliers and moving air defeats them, which is why porch fans in this region are a functional item rather than a decorative one. If your rental has one, it is worth checking it works as part of the turnover.

Tell guests before they find out

A line in the welcome guide costs nothing and changes how the experience reads: sand gnats are a Lowcountry fact, they are worst around dawn and dusk in spring and fall, the porch fan helps, and repellent is in the drawer. Leaving repellent in the property is a small gesture that gets mentioned in reviews far more often than it costs.

A guest who was warned treats it as local character. A guest who was not treats it as a problem with your property.

If your porch has standing water or leaf litter accumulating between bookings, that is worth flagging on the turnover rather than after a review. Call Savannah STR Cleaning on (912) 666-2994 with the checkout time and the next arrival.
