DEP to Spray Abington, Upper Dublin for Mosquitoes

The Pennsylvania Department of Environmental Protection will spray portions of the two townships Thursday night.


The Pennsylvania Department of Environmental Protection will conduct an Ultra Low Volume mosquito adulticide spray in portions of Abington and Upper Dublin today, Aug. 23.

Pennsylvania DEP Southeast Regional Office Community Relations Supervisor Deborah Fries said the spraying is in response to a mosquito surveillance program; many mosquitoes in the five-county region have tested positive for the West Nile Virus.  

The spraying is part of the DEP’s West Nile Virus control program, and is done in conjunction with the Montgomery County Health Department. 

Spraying will happen in the area between Fitzwatertown, Susquehanna, Jenkintown and Edge Hill roads; Penbryn Park will also receive attention.

The Pennsylvania DEP will perform the spraying between 8 and 10:30 p.m. using truck-mounted spraying equipment; the equipment will have the business license BU2626. 

The rain date is Friday, Aug. 24.

The product used in the spraying will be Duet and/or Biomist 3+15 at a rate of 0.75 ounces per acre. According to a DEP press release, these products are “designed to provide quick knockdown and effective control of adult mosquitoes.”

Fries said both of the chemicals are EPA approved, "low odor," and burn off quickly in the sun following morning. She said that she wouldn’t go as far to recommend that people come inside, but said some people may want to bring their pets inside during the spraying. 

As of today, 81 mosquitoes tested positive for West Nile Virus in Montgomery County; no humans tested positive for West Nile Virus in Montgomery County, though seven Pennsylvania counties had at least one human case, including Bucks County.

According to the Centers for Disease Control, of the eight reported human cases of West Nile Virus in Pennsylvania, five were neuroinvasive disease cases, meaning the disease affected the person’s nervous system. (Click here for more information on the CDC’s website.) The other three cases were less serious, according to the CDC.

Nationally, there have been a total of 1,118 cases of West Nile virus disease in people, including 41 deaths. According to the CDC, about 75 percent of the cases have been reported from five states including Texas, Mississippi, Louisiana, South Dakota and Oklahoma – and half of those cases were in Texas.

Amanda Witman, of the Pennsylvania DEP said in an interview in June that mosquitoes are most prevalent at dawn and dusk. Witman said to take precautions against the disease by eliminate standing water in pots, tires, wheelbarrows, wading pools and birdbaths.

Witman also said there have been fewer West Nile cases in humans over the years.

“We have had a steady decline in human positives over the last several years, but it’s always something to be aware of, especially when it comes to elderly people, children, or those with compromised immune systems,” Witman said.

I have spoken to Deborah Fries (484-250-5808) of the DEP. Spraying will start at Penbryn Park at 7:45 and will continue to the area outlined. I was told that my street, Tyson Ave, will be fogged by the truck as it drives through the area. You'd need to call her to find out about other specific streets. The spray will be Duet, which contains sumithrin and prallethrin. I was told that individuals are welcome to research these pesticides and decide for themselves what their comfort levels are as far as being outside, etc. Links will follow in a second comment, as it won't all fit in one. I think it is important to be informed so precautions can be taken. Personally, if I had an infant or an elderly or ill person in my home, I would want to know these things, so I am sharing this information for anyone else who might want to know.

For sumithrin I found this... http://www.auburnguide.com/Pages/AuburnMA_Health/Spraying%20FAQ.pdf " If the immediate area of your home is being sprayed, keep windows closed and fans off during the time spraying occurs. Shut off air conditioners unless they have a setting for recirculating indoor air. In very hot weather, make sure you open the windows or turn fans and air conditioners back on soon after the spraying is completed in your immediate area. If you are not sure if your air conditioner can be set to recirculate indoor air, turn it off when spraying is occurring in your immediate area. · Rinse any homegrown fruits and vegetables with water. · Keep pets indoors when spraying is occurring in your immediate area to minimize their risk of exposure. Pets that remain outdoors could be exposed to small amounts of pyrethroids, but would not be expected to experience adverse health effects from the spraying. Again, there are many pesticide products (e.g., flea collars, pet shampoo, dips) containing sumithrin that are used directly on pets to control ticks and insects. · If skin or clothes or other items are exposed to the sprayed pesticide, wash with soap and water. · If the spray gets in your eyes, immediately rinse them with water or eye drops, and call your doctor. " Information for prallethrin was a bit sketchier, but I found this... http://www.pesticideinfo.org/Detail_Chemical.jsp?Rec_Id=PC35755

p.s. Thank you to Patch, since this was the only site where I had any notice of this.

6abc news mentioned it Tuesday but not in detail. Wish I knew if it was safe for our air conditioners to be on during spraying on our street. I had to put my 10 month old to bed with just the ceiling fan. Too bad it wasn't done while its been cool the past several days.

Hi Kelly, I did see the truck go down Tyson at @8:20. It would be nice to know when each street is done. Hope that helps you in some way.
