Dead Bird Reporting Informational Flyer

Once again this year, through a grant from the Pennsylvania Department of Environmental Protection, Delaware County Intercommunity Health Coordination will be overseeing a West Nile virus mosquito surveillance and control program throughout Delaware County.  The Penn State Cooperative Extension located in Smedley Park, Springfield, will be providing these services to the County.

What is West Nile virus?

West Nile encephalitis describes a brain infection caused by West Nile virus (WNV).  Cases occur primarily in the late summer or early fall, although mosquito season is usually April through October.  People can get infected from the bite of certain species of mosquitoes that are infected with the virus.  Although most infections are mild, serious illness can occur.  In 2011 WNV was detected in 95 mosquito samples in Delaware County.  There was NO human case of WNV in Delaware County last year.

Will my neighborhood be sprayed for mosquitoes?

Spraying for adult mosquitoes (adulticiding) is just one part of any mosquito management program.  Mosquito surveillance, which is done by setting up mosquito traps and looking for areas where mosquitoes breed, and larvaciding (treating mosquito eggs) typically make up about 95% of the program, however, adulticiding is called for at certain times.

Adulticiding is based on data that is collected by trapping mosquitoes and is extremely important when deemed necessary.  The Pennsylvania Department of Environmental Protection (DEP), along with the Penn State Cooperative Extension, will be conducting daily surveillance by setting up mosquito traps throughout Delaware County from spring until fall.  If high numbers of mosquitoes are detected and/or mosquitoes test positive for WNV, DEP, in consultation with the Penn State Cooperative Extension and county and municipal officials, may decide that adult spraying is necessary to protect the health of the general public.  All truck-mounted spray events will be planned at least 48 hours in advance. 

If you would like to be notified of all spray events in Pennsylvania you are strongly encouraged to register your e-mail address with DEP’s News Releases distribution list by visiting
www.ahs2.dep.state.pa.us/WestNileNews/default.aspx.

Positive bird findings do not present an immediate need for spraying.  The testing of birds simply helps us to determine that WNV is present somewhere in the area but does not identify the specific location where the bird contracted the virus.  Once a bird has tested positive for WNV, surveillance is enhanced in that general area to test for mosquitoes carrying the virus.

What can I do to reduce my risk of WNV?

Residents can take a few simple steps around their homes to reduce the risk of contracting WNV.  Mosquitoes need water to breed, so if you eliminate their breeding spots you reduce their numbers.  Even just a small amount of standing water can become home to many mosquitoes in as few as four days.

What should I do if I find a dead bird during WNV season?

The West Nile virus infects certain wild birds. The infected birds, especially crows, are known to get sick and die from the infection. Reporting of dead birds is a good way to check for West Nile virus activity in the environment.  The Pennsylvania Dead Bird Surveillance program for West Nile virus relies on Commonwealth citizens to report and submit certain dead birds seen around their property or elsewhere to their West Nile County Coordinators. Since the virus was detected in New York City in 1999, thousands of dead birds have been submitted for testing by citizens in the northeastern US. Pennsylvania residents are strongly encouraged to report selected species of dead birds on-line via the Internet. The Pennsylvania West Nile Virus Control Program will only collect Corvids, Raptors and Jays beginning June 1.  Corvids include crows and ravens.  Raptors include eagles, falcons, hawks, buzzards and owls.  Blue jays are included in the Jay group. 

Residents should take the following steps when they see a dead bird:

The Pennsylvania Department of Environmental Protection is collecting 5 birds per week from each county for testing for West Nile Virus from June 1 through October 1, or until the season ends.

Avoid bare-hand contact when handling dead birds. Use rubber gloves when handling a dead bird.

If you do not have gloves, insert your hand into a plastic bag, grasp the bird carefully and invert the bag over the bird. Each bird should be placed in tied plastic bag, and then placed inside a second tied bag.

If you are not submitting the bird for testing, the bagged bird can be placed in the trash.

Wash hands thoroughly with soap and water after discarding the dead bird.

Pennsylvania Hypersensitivity Registry

This registry, which is maintained by the Pennsylvania Department of Agriculture (PDA), is a list of people who have been verified by a physician to be excessively or abnormally sensitive to pesticides.  Commercial and public pesticide applicators must contact anyone on the registry whose listed location is within 500 feet of a pesticide application site.  By having prior notification, the sensitive individual can take appropriate precautions.

PDA will send, by mail, the registry to each licensed commercial/public pesticide application business.  The registry is now published twice a year in March and July.  A person will not be considered included on the registry unless their name appears on a current registry.  A request for listing on the registry must be received by PDA at least two months before an effective date.

For more information or an application, please call PDA at 717.787.4392
