AERIAL MOSQUITO SPRAYING UPDATE 9/9/19 10:30 AM
AT THIS TIME THERE ARE NO PLANS TO SPRAY IN THE WARREN AREA.
Aerial spraying in northern Rhode Island (parts of Burrillville, North Smithfield, and Woonsocket) was not completed last night due to falling temperatures. Spraying in these areas, and parts of southern Rhode Island (including parts of Westerly, Hopkinton, and Charlestown) is planned for tonight. Spraying will start at dusk tonight and will be completed by 4:30 am Tuesday morning. We will provide more details on the timing when the flight plan is finalized just before take-off.
While spraying is occurring, it is best to err on the side of caution and limit time outdoors and keep your windows closed. The product being sprayed is being used at very low concentrations. No adverse health risks are expected with its use for mosquito control. However, it is generally good for people to limit their exposure to pesticides.
On Sunday night and early Monday morning, spraying was done in all of West Warwick and parts of Coventry, Cranston, Warwick, East Greenwich, and West Greenwich, as well as all of Central Falls, Pawtucket, and North Providence and parts of Providence, East Providence, Smithfield, Lincoln, and Cumberland.
Aerial spraying to protect humans from EEE infection will touch parts of 21 communities encompassing a total approximate area of 110,000 acres.
Sometimes the state and/or local communities ground or aerial spray pesticide to control mosquitoes in a variety of environments such as outdoor residential and recreational areas, commercial urban areas, and rural areas. Mosquitoes are a nuisance that impact quality of life, and they also can carry diseases, such as Eastern Equine Encephalitis (EEE) or West Nile Virus (WNV).
When is aerial spraying of insecticides considered?
In situations where there is an elevated risk of human disease, state or local officials may consider the use of an aerial pesticide spray in the evening and overnight hours to reduce the number of infected, adult mosquitoes in the specific areas of elevated risk. Many breeding areas of high concern are not accessible by truck-mounted ground sprayers. It should be noted that although the aerial spraying is considered necessary to reduce human risk, it will not eliminate risk. It is critical that residents protect themselves from mosquito bites by staying indoors during peak mosquito hours, applying insect repellent when outdoors, draining standing water where mosquitoes breed, repairing screens, and protecting animals and pets.
Why is my location not in the spray area?
The spray area is designed to target areas that mosquito-borne disease activity originates from. There are several possible reasons why your location may not be in the current spray area, the most common being that you are not located in an area that has been determined to have a risk of mosquito-borne virus amplification sufficient to warrant spraying.

Back to School Health Alert: 'Smart Scheduling' and Mosquito and Tick-Borne Disease Prevention Resources
Back-to-School time coincides with the time of year that the risk of mosquito-borne diseases, like Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV), peaks in Rhode Island. The mosquitoes that carry these diseases bite until the first frost (usually around the end of October).
To date, in Rhode Island, there have been two findings of EEE (in Central Falls) and no findings of WNV in mosquito samples. The 330 positive EEE mosquito pools in Massachusetts, coupled with multiple findings of both EEE and WNV in mosquitoes from eastern Connecticut, however, clearly indicate this remains a higher-than-average risk summer for mosquito-borne diseases in southeastern New England. Massachusetts has announced four human cases of EEE, including one death. Also, two horses, one from Mendon and another from Uxbridge, have tested positive for EEE.
The Rhode Island Department of Health (RIDOH) recommends “smart scheduling” whenever possible as a precaution against seasonal mosquito-borne illness. These recommendations should be considered when planning all back-to-school outdoor activities, including games and practices for all sports. Mosquito-borne diseases are more prevalent in late summer and early fall until the first hard frost eliminates the season’s mosquitoes.
Whenever possible, avoid scheduling games and practices during early morning or dusk hours, or relocate activities to an indoor venue during these times. This will help minimize the risk of mosquito bites for players, coaches, and spectators alike — which may include individuals more vulnerable to severe illness, such as the elderly and people with weakened immune systems.
At a minimum, RIDOH recommends that schools and organizations remind all participants in outdoor activities to protect themselves from mosquito bites. They should:
- Avoid outdoor activities during dawn and dusk. Mosquitoes are most active at this time.
- Wear an insect repellent with no more than 30 percent DEET — if they must be outside at dawn or dusk: (Insect Repellent Essentials: A Brief Guide)
- Wear long-sleeve shirts and long pants when possible to avoid exposing skin to mosquitoes.
We also ask that facility staff be reminded to remove or cover anything around school grounds and athletic fields that might allow water to collect (for example, bird baths), or frequently empty anything that collects standing water. Just one cup of water can become a breeding ground for hundreds of mosquitoes.
Over the coming weeks and months, RIDOH will continue to update school departments whenever conditions change. In the event that a greater threat of mosquito-borne disease is observed, public health officials may advise all schools and leagues to reschedule events and/or offer additional recommendations.
If you need additional information about smart scheduling or about personal protection from mosquito bites, please contact RIDOH's Health Information Line at 401-222-5960.
