Mosquito Borne Disease
There are steps you can take to reduce the presence of mosquitoes on your property – mainly reducing standing water. Even a little bit of standing water – that might accumulate in the saucer of a plant pot after a rainstorm – can be an active breeding ground for mosquitoes. Other places that could be good mosquito breeding grounds include:
- Discarded tires
- Rain barrels, buckets
- Abandoned boats
- Clogged roof gutters
- Bird baths
- Abandoned or untreated swimming pools, wading pools
- Ceramic pots, empty cans
- Anywhere water can collect!
Section 19-13-B31 of the Connecticut Public Health Code states that “no person shall maintain or permit to be maintained any pond, cesspool, well, cistern, rain barrel or other receptacle containing water or accumulation of stagnant water in such a condition that mosquitoes may breed therein or may injure health or cause offense to other persons”.
If you need assistance or advice treating standing water on your property, a member of our Environmental Health staff can help. Ledge Light Health District has purchased a supply of larvacide briquettes that can be used to treat standing water on private property. This larvicide prevents mosquitoes from developing into adults. An Environmental Technician will visit your property and apply the larvicide to the area of standing water. The treatment will last approximately 30 days. Contact Joseph Blanchard at (860) 448-4882 ext. 1308 (towns East of the Thames River) or Patti Myers at (860) 434-1605 ext. 214 (towns West of the Thames River) for more information.
Some things you can do to avoid mosquito bites include:
- Minimizing time outdoors at dusk and dawn.
- Ensuring door and window screens are tight-fitting and in good repair.
- Wearing shoes, socks, long pants, and long-sleeved shirts. Clothing material should be tightly woven.
- Using mosquito netting when sleeping outdoors.
- Using mosquito repellent when necessary – in a safe manner according to the label instructions.
A mosquito-borne viral infection which may also be sexually transmitted and an increase in birth defects among infants born to women infected during pregnancy is associated with the virus. The mosquitoes associated with Zika are Aedes aegypti (not found in CT) and a related species Aedes albopictus, which has been found in the southwestern area of the state. Aedes albopictus is typically found in and around buildings and they become infected after feeding on an infected person and transmitting it to the next person.
West Nile Virus
West Nile Virus is a mosquito-borne viral infection that is transmitted by the culex species of mosquito. Most people infected with the virus experience no symptoms; however, the disease may be serious or even fatal. Certain populations such as the very young, the elderly and the immune-compromised may be a special risk.
Eastern Equine Encephalitis
Eastern Equine Encephalitis (EEE) is a rare but serious disease caused by a virus that is transmitted by mosquitoes.
Connecticut residents are advised to protect themselves and their children by avoiding outdoor activity from dusk to dawn, when mosquitoes are most active.
