Lowell, Mass., July 17, 2026 – West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE) are two of the diseases most commonly transmitted to humans by the bite of an infected mosquito.

The mosquitoes that carry these viruses are common throughout the state and are found in urban as well as more rural areas. While WNV and EEE can infect people of all ages, people over the age of 50 are at higher risk for severe infection.

As a result, the City of Lowell has requested the Central Mass. Mosquito Control Program (CMMCP) to preventatively treat several areas within the city. These sites, inclusive of surface streets in the area, are:

• Cawley Stadium Complex – 424 Douglas Rd
• JG Pyne Elementary School – 145 Boylston St
• Ventura Field – 303 Boston Rd
• Shedd Park Complex – 495 Rogers St
• Butler Middle School – 1140 Gorham St
• Shaughnessy Elementary School – 1158 Gorham St
• Westlawn I Cemetery – 1375 Gorham St
• Westlawn II Cemetery – 305 Boston Rd
• Edson Cemetery – 305 Boston Rd/1375 Gorham St
• Patrick Cemetery – 1251 Gorham St
• Holy Trinity Cemetery – Gorham St
• Old English Cemetery – Gorham St
• Lowell Cemetery – 77 Knapp Ave

Spraying will begin at dusk (approximately 8:30PM) on Wednesday, July 22, through completion but no later than 11:00PM. In case of inclement weather, services will be rescheduled for Wednesday, July 29, 2026.

A full street listing is available for review on the City of Lowell website or the CMMCP website.

By taking a few common precautions, people can help to protect themselves and their loved ones from mosquito borne illnesses:

Avoid Mosquito Bites

• Apply Insect Repellent when you go outdoors.Use a repellent with DEET (N, N-diethyl-mtoluamide), 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-sleeved shirts, 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 the 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.

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. Contact CMMCP to treat unused swimming pools or to reclaim used rimless tires that can be used by mosquitoes to breed.
• Install or repair screens.Some mosquitoes like to come indoors. Keep them outside by having tightly fitting screens on all your windows and doors, covering up and/or wearing repellent.

FREE SERVICES: CMMCP is also available for free to any resident who would like to have their property sprayed or unused swimming pool preventatively treated. Additionally, CMMCP has a used tire reclamation program for residents who wish to dispose of tires removed from the rims.
