Wednesday Night, Department of Environmental Management (DEM) and Rod The Island Health Department (RIDOH) announced that the state will make an aerial application for "larvicide" on Thursday.
The locations are the Chapman Marsh in the Western City, where two open mosquito encephalitis (EEE) mosquitoes and one horse show have been found; the South Branch of the Pautuset River in West Warwick, near the first human EEE case in the country; and the Valley Marsh area, surrounded by Lincoln, Cumberland and Central Falls, the city where the state's first two EEE discoveries were announced on August 1
Flights on Thursday depend on weather conditions that need to be calm.
As announced in August On September 30 and 3, the latest mosquito trapping detection traps confirm the need for increased use of pesticides and the state is making all necessary preparations to carry out campaigns to kill both larvae and larvae. of adult mosquitoes. Larviciding refers to the application of a product that kills mosquito larvae before they mature into adults. The air application, which will be done tomorrow, affects all mosquito species and reduces the risk of both EEE and West Nile virus (WNV) infections.
According to state official products, the product used in the applications is called Bti, a naturally occurring bacterium that comes in granular form. The EPA has concluded through various studies that Bti poses no risk to humans. Bti bags will be loaded onto a helicopter that dispenses granules / pellets with precision into marshes and other breeding sites to control mosquito breeding. Bti produces toxins that specifically affect mosquitoes, black flies and fungi only. These toxins do not affect other insect species, including honey bees. It has been approved for pest control in organic farming operations.

Since the last round of capture on August 26, DEM has added traps in West Warwick; Burrillville, North Smithfield and Cumberland, which border several Worcester County communities identified by high-risk public health officials in Massachusetts; and West Greenwich, near the southeastern Connecticut state line, where there are numerous findings of EEE in mosquitoes and two cases of EEE virus infection reported in horses. With the participation of public health experts at RIDOH and entomology experts at the University of Rhode Island, DEM now places nearly 40 mosquito traps in 23 communities across the state. DEM sets traps strategically based on knowledge of environmental conditions conducive to increasing EEE and WNV in mosquito populations.
The state will publish a broadcast schedule and additional information before conducting any adult flights. 'Adulticiding' is a method of controlling adult mosquitoes to control the outbreak of mosquito-borne disease. It is often applied by aircraft through sprinklers that spray very fine aerosol droplets that stand off and kill flying mosquitoes upon contact.
Previous RIDOH recommendations remain in place and are related to the prevention of both EEE and WNV. On Monday last week, RIDOH recommended that schools and community leaders play outdoor games, practices and other activities planned to take place in the early morning or dusk, be redeployed earlier in the afternoon, or move indoors. The event's "smart schedule" is intended to help reduce the risk of mosquito bites for players, coaches and spectators. RIDOH recommends that smart planning stay in place for the rest of the mosquito season, which typically ends in mid-October (after the first heavy frost).
