Mosquito Update
The North Andover Board of Health wants to update the residents regarding the status of local mosquitoes and the actions being taken in the area.
North Andover Board of Health has been performing weekly mosquito testing for West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE) since April and have not had a positive mosquito pool yet this season. Neighboring towns also perform weekly surveillance and positive WNV and EEE mosquito pools have been detected in neighboring communities. We have been in contact with Mosquito Control and our risk level is currently Low. We will be conducting adulticide and barrier mosquito spraying on town and school properties to reduce the mosquito population and provide protection for the remainder of WNV and EEE season on Monday, August 5 beginning at 8:00pm to 12:00am. Please look at the notice provided by Mosquito Control for the properties that will be treated and additional information. We will continue to perform surveillance in North Andover throughout the remaining mosquito season.
We urge all residents to read and follow these important safety tips:
-
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.
-
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.
