Source reduction time. We are collecting tires (passenger vehicle size & no rims) at Salem High School until noon today.
Tires hold water and mosquitoes love it for breeding. Let us take them for you.
By the way..there’s a service request for that and we’ll come to you.

Residential adulticide (truck spraying) has ended for the 2026 season. NEMMC will continue to concentrate on mosquito virus prevention throughout the district.

Thank you to our member communities and residents for another busy mosquito season. Updates for 2027 will be posted in May.

WNV Risk Level - MODERATE- Amesbury, Beverly, Danvers, Hamilton, Ipswich, Manchester, Merrimac, Middleton, Salisbury, Topsfield, Wenham

The Massachusetts Department of Public Health (MDPH) announced a risk level increase to MODERATE for West Nile virus (WNV) in the above towns. WNV is transmitted to humans from the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state and are found in both urban and rural areas. While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe infection.
By taking a few precautions, people can help to protect themselves and their loved ones until heavy frost:
Avoid Mosquito Bites
• Apply Insect Repellent when you go outdoors. Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), IR3535 or oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] according to the instructions on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age. Permethrin products are intended for use on items such as clothing, shoes, bed nets, and camping gear and should not be applied to skin.
• Clothing Can Help reduce mosquito bites. Although it may be difficult to do when it’s hot, wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
• Be Aware of Peak Mosquito Hours - The hours from dusk to dawn are peak biting times for many mosquitoes. When risk is increased, consider rescheduling outdoor activities that occur during evening or early morning. If you are outdoors at any time and notice mosquitoes around you, take steps to avoid being bitten by moving indoors, covering up, and/or wearing repellent.
Mosquito-Proof Your Home
• Drain Standing Water – Many mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or getting rid of items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools and change water in birdbaths frequently.
• Install or Repair Screens - Some mosquitoes like to come indoors. Keep them outside by having tightly fitted screens on all your windows and doors.
Local Health Departments continue to work closely with the MDPH, other agencies, and locally with the Northeast Massachusetts Mosquito Control District (NEMMC) to control mosquitoes in these towns. In response, NEMMC will continue to identify areas in the district that require treatment for larval control.
If you have areas of standing water around your home or any old passenger tires left outside, please Request Service for larviciding site inspection and/or Tire Removal.

🚨Please protect yourself, you are your first line of defense👊

The Massachusetts Department of Public Health (MDPH) announced a risk level increase to HIGH for West Nile virus (WNV) in Revere & Winthrop. Due to a human case in Suffolk County.

We've been receiving lots of calls asking when the adulticide (truck spraying) will end for the season. As of right now the last day for requests will be 9/16 for final service on 9/17. That may change pending weather, surveillance amounts, virus, and overall number of requests. Once the decision is made - this page, website, and office voicemail will be updated. Thank you.

Weather Update & Spraying Requests Last Night 8/20/26

Weather conditions varied throughout the district, with some areas remaining dry long enough for our technicians to complete treatments, while other areas received steady rain sooner than expected. Our technicians treated as many requests as allowed before the rain moved in. Confirmation and cancellation emails are being sent.

If you have a friend across town who was treated while your property was not, the difference in weather conditions is the reason.

If you feel your property still needs treatment, please submit a new request for next week.

As a reminder, spraying requests are accepted Sunday through Wednesday at noon.

Thank you,

NEMMC

🚁Aerial larviciding this morning over the salt marsh uplands. After learning yesterday about how many and quickly the mosquitoes hatch 🤯 imagine the clouds of the hungry little blood suckers that would infest the area. Those with bite allergies wouldn’t be able to leave the house😕

08/11/2026

While NEMMC staff are busy treating 74,000+ catch basins, aerial larviciding, virus surveillance, and more, we’re also conducting pesticide resistance testing in partnership with NEVBD and the Dept. of Entomology at Cornell University.
These photos show how quickly mosquitoes can turn a little water into a LOT of flying adults.
The egg rafts pictured here were created in less than 15 hours after placing gravid water (aka stinky water) at locations throughout the district. Each tiny raft can hold 150 - 300+ eggs, those eggs hatch into larvae in about 24 hours, and in 4–10 days emerge as flying adult mosquitoes. 🦟🦟🦟
Take a look at the number of what will become adult mosquitoes represented in each photo.
So, when we say even a capful of standing water can produce hundreds of mosquitoes, we’re not kidding. 😳
👉 The best mosquito control starts at home. Take a few minutes to walk around your property and dump, drain, or turn over anything holding standing water.
A little water can go a long way when it comes to mosquitoes. 💧➡️🦟
