Tick surveillance in six Loudoun County parks began in May for the 2014 season. The six parks include:
Recommendations for spraying will be guided by surveillance results. As of May 2014, it is not envisioned that any insecticide use would occur in the Banshee Reeks Nature Preserve.
The product used in 2012 and 2013 was called Talstar, which is a commonly used insecticide to control ticks and other pests. Talstar is a bifenthrin-based product and is approved by the U.S. Environmental Protection Agency for this type of application.
It is recommended that people and domestic pets do not enter sprayed areas until the areas have dried after having been sprayed. This is dependent upon the weather; however, the product typically dries within 2 to 3 hours. The county will have staff on-site to ensure that members of the public do not enter these areas until the spraying is complete and the areas have dried completely.
If a person (including a young child or a pregnant woman), or animal were to swallow, breathe or touch the chemical, the individual or animal is not likely to become ill. If the chemical comes into contact with the skin or eyes before it has dried, some individuals may have short term irritation that will likely disappear within 12 hours. There are no studies that would indicate bifenthrin exposure risks in humans are increased for children or women who are pregnant.
Bifenthrin is approved not only for outdoor use but also for spot treatment indoors for pests such as:
According to the Centers for Disease Control and Prevention, when this pesticide is used properly by a professional, there are negligible risks to wildlife. However, the chemical can be toxic to fish and aquatic invertebrates, thus the pesticide control professionals will not apply the chemical near ponds or streams. This chemical is not mobile in soil meaning that there is very little potential for it to enter the ground water.
If you believe you may be affected by the spraying more than the average person, stay away from the treated area for 24 hours.
