Dress onā€ˆLittle St. Simons Island is always casual, comfortable and functional. Even our evening cocktail receptions and dinner are “dress as you like” affairs.


Insects

In this pristine coastal environment, insects are an integral part of life. During the warmer, wetter months, guests feel comfortable in light, long-sleeved shirts and long pants. Insect repellents, in a variety of types, are available on a complimentary basis at all guest houses and at the Hunting Lodge.

Little St. Simons Island (LSSI) is located in the Altamaha River Delta. This delta is one of the most intact and biologically rich delta systems on the East coast of the United States, and has been widely recognized across the country. It includes several thousand acres of high salt marsh, which is a productive habitat for mosquito larvae. When the Georgia coast has large amounts of rain or extreme tides, areas of high marsh can fill with water and the mosquito eggs hatch. Adult mosquitoes lay their eggs in mud and when the mud is covered with water again for an extended period of time, those eggs hatch, and then over the course of about a week the larvae pupate into adult mosquitoes. These intense hatches have been part of the natural ecology of this region for at least hundreds of years and there is historic documentation from the 1700s describing the masses of mosquito around the Altamaha delta.

Historically, LSSI allowed Glynn County Mosquito Control to spray chemicals aerially to kill adult mosquitoes (“adulticide”). We know now that not only does the adulticide kill mosquitoes, but it also has negative effects on a number of other species including butterflies, dragonflies, crabs, fish, and even nesting songbirds. As we began increasing our conservation management efforts, we no longer allowed the county to spray adulticide. In 2008, we began working with Glynn County to apply larvacide, which only affects mosquito larvae and no other species.

The larvacide chemicals that we use are growth inhibitors, meaning that they do not kill the mosquito larvae, but they prevent them from developing into adult mosquitoes. Even after our marshes are treated by larvacide from the county, you could potentially see large numbers of mosquito larvae in the marshes. In addition to LSSI, other islands and marsh areas in the Altamaha River Delta are breeding mosquitoes, likely including Egg Island and Wolf Island. These islands are part of the National Wildlife Refuge system and are designated wilderness areas, so no chemicals are allowed to be applied. Despite the frequent mosquito hatches in the warmer months, most guests feel the beautiful nature of the island outweighs the biting insects. No matter how annoying the bugs are, the overall health of the ecosystem is more important.

There are numerous species of mosquitoes, but the most common one on the barrier islands is the salt marsh mosquito. It is capable of traveling 25+ miles, depending on the winds, and lives for about two weeks. Fortunately, this species is not the type of mosquito that commonly carries diseases like West Nile or Encephalitis.
