[weather permitting] - Rain dates—May 23 or 24

The Tuscarora Nation will be conducting an aerial spraying with the insecticide known as Foray (Btk) for the control of gypsy moths. Duflo Aerospray Systems will be applying the spray in the early morning hours following sunrise, over approximately 2600 acres of the Nation. The spraying should be followed by a calm dry day to be the most effective. If the weather begins to turn wet or windy, the spraying maybe delayed by a day or longer. Please call 609-3810 for an update on the dates.

The spray is not a chemical but a bacteria (bacillus thuringensis) that requires ingestion by caterpillars to be active. The insecticide is not harmful to humans, plants, animals and very few insects. The spray does not affect vegetable gardens or swimming pools although motor vehicles may need to be washed with soap and water if covered with the spray (the spray usually has a red or purple tint which may stick to surfaces easily). It is recommended that you remain indoors during the spraying, as the particles in the air may pose breathing problems for some people. This mild irritation from the dust size particles is the only other precaution that comes with the spray.
Finally, the majority of homes on the Nation are not included directly within the spray blocks, instead, the aerial spray covers forests with high gypsy moth populations and significant defoliation. You can check the map above to see the areas that will be sprayed. The green shapes represent the 'spray areas' the airplane will fly to distribute the insecticide.

What is Bt?



Bacillus thuringiensis (Bt) is a bacterium commonly found in nature as a normal resident of soil. It occurs in many forms, several of which are used as biological pest control agents on food crops - including organically grown foods. Bacillus thuringiensis var. kurstaki or Btk, makes a crystal which affects the Gypsy Moth larva or caterpillar. In order to work, the bacterium must be eaten by the Gypsy Moth caterpillar. Conditions needed for the Btk to be activated are found only in the stomach of moths and butterfly caterpillars. These conditions are not found in animals, birds and other desirable insects such as bees, beetles, and spiders. Nor are these conditions found in people.



Can Btk make people sick?

Btk has an excellent safety record for humans. If you eat vegetables, you probably have already ingested this bacterium. It is commonly used on commercial, and even organic, produce. The safety has been established both b
