The Andover Health Division was notified Friday that mosquito pools on Haggetts Pond Road near Gavin Circle and on Chatham Road tested positive for EEE. This is the second positive test for EEE this month among mosquitoes tested in Andover.
Additional testing on Abbot Street yielded a negative result.
As a result of the most recent positive tests, the Northeast Massachusetts Mosquito Control and Wetlands Management District is deploying supplemental mosquito traps to the other areas this weekend. Mosquito spraying will take place on Monday between 8 p.m. and midnight. The spraying will be postponed to Tuesday night if there are weather problems.

"We're prepared to take aggressive steps to combat this issue, and have already planned for additional treatment in the areas identified," Health Director Carbone said. "We will work closely with our partners at Mosquito Control to ensure that this is addressed efficiently and effectively, but it's important for everyone to be aware of the risks and exercise caution throughout the remainder of the season."

As always, the Andover Health Division urges all residents to read and follow these important safety tips:
Avoid Mosquito Bites
- Be aware of peak mosquito hours: The hours from dusk to dawn are peak biting times for many mosquitoes. Consider rescheduling outdoor activities that occur during the 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.
- Clothing can help reduce mosquito bites: Although it may be difficult to do when it’s hot, wearing long sleeves, long pants and socks while outdoors will help keep mosquitoes away from your skin.
- Apply insect repellent when you go outdoors. Use a repellent with DEET, permethrin, picaridin, IR3535 or oil of lemon eucalyptus 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 percent 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 directly to your skin.

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 window and door screens: Some mosquitoes like to come indoors. Keep them outside by having tightly-fitting screens on all of your windows and doors.

According to the Centers for Disease Control and Prevention the EEE virus is a rare cause of brain infections or encephalitis. Very few human cases are reported across the U.S. each year, but EEE can be fatal or leave victims with serious complications and neurological problems.
