• Make sure windows have screens. Repair or replace screens that have tears or holes.
• Eliminate any standing water from your property and dispose of containers that can collect water. Standing water is a violation of the New York City Health Code.

PESTICIDE WILL BE SPRAYED TO REDUCE WEST NILE VIRUS IN BROOKLYN

Update: Spraying has been postponed until September 7th/8th.

-----------------------------------------

Pesticide Spraying

Tuesday, September 6th, between 8:30 p.m. and 6:00 a.m.

To reduce mosquito activity and the risk of West Nile virus, the Department of Health and Mental Hygiene (DOH) will conduct mosquito adulticide treatments in parts of Brooklyn. DOH sprays in neighborhoods where its surveillance has found an increasing number of mosquitoes that are infected with West Nile virus.

"West Nile virus is spread through the bite of an infected mosquito. West Nile virus can infect humans, birds, horses and other mammals."

To kill adult mosquitoes, trucks will spray pesticides between 8:30 p.m. on Tuesday, September 6th, and 6:00 a.m. on Wednesday, September 7th. If spraying is delayed because of bad weather, it'll be done during the same hours on Wednesday, September 7th/Thursday, September 8th.

DOH states that very low concentrations of Anvil® 10+10 or Duet® will be used and that the risks associated with these pesticides for mosquito control are low to people and pets. The active ingredients in Anvil are sumithrin and piperonyl butoxide. In Duet, they're sumithrin and prallethrin.

However, some people who are sensitive to the spray's ingredients could experience short-term eye or throat irritation or a rash. People who have respiratory conditions, such as asthma, could also be affected. If you have a stronger reaction to the pesticide after it's been sprayed, call the New York City Poison Control Center. Its phone number is 212-POISONS (212-764-7667).

How to keep yourself safe while spraying is being done:

• Stay indoors, whenever it's possible. 
• Keep doors and windows closed for thirty to sixty minutes after spraying is finished.
• If you keep your air conditioner on, you might want to either close its vents or use the recirculate function. 

What to do after spraying has been completed:

• Wash any skin and clothing that's been exposed to the pesticides with soap and water. 
• Wash fruit and vegetables thoroughly with water before cooking or eating them. 

How to reduce your exposure to mosquitoes:

• Use an approved insect repellent that contains DEET, picaridin, oil of lemon eucalyptus (not for children under 3), or products that contain the active ingredient IR3535. 
• Make sure that windows have screens and repair or replace any that have tears or holes. 
• Eliminate all standing water from your property and dispose of containers that can collect water. Having standing water on your property is a violation of the New York City Health Code. 
• Make sure your roof gutters are clean and are draining properly. 
• Clean and chlorinate swimming pools, outdoor saunas, and hot tubs. Keep them empty or covered when they aren't in use. Drain the water that collects in the pool covers. 

If you see standing water, you can report it by calling 311 or visiting https://portal.311.nyc.gov/article/?kanumber=KA-02298.

MOSQUITOES THREATEN HEALTH

How to take action on our mosquito problem

Hi all,

I called Brad Lander's office today, and they would like everyone to call 311 to report this problem to establish a paper trail of complaints. Tell 311 that you want to report a terrible mosquito problem in the neighborhood to the Department of Health. Let them know the mosquitoes are coming up from the sewer drains in front of our houses and in the street. Tell them that it is a standing water issue (even beneath the ground) and that the Health Commissioner has asked for these complaints to be filed

Please send a record of your complaint number, address, and any letters or other documentation to Brad Lander's assistant, Jessica Turner, who will work with us on this: JTurner@council.nyc.gov, tel. 718-499-1090, fax 718-499-1997. Also, please let me know so I can work on compiling a master list.

Brad Lander will be meeting soon with the Commissioner of the Department of Health to discuss several matters, and this will be on the agenda.

Please take a moment to call 311 and report this problem. There is power in numbers. Don't forget, these Asian tiger mosquitoes are vectors for various diseases, including West Nile, dengue and chikungunya, to name a few, so are not only a nuisance but also a health risk. (I actually wrote an article about them for The Washington Post, if you'd like some more information:
http://www.washingtonpost.com/wp-dyn/content/article/2008/08/15/AR2008081503123.\html).

Maybe if we get some assistance from the city on this, we will be able to enjoy our gardens next year......
