The product is applied to the treetops by low flying aircrafts where spongy moth caterpillars are feeding, often this occurs in May and June.
When the caterpillars feed on the leaves, they ingest the products. The bacterium in Foray is toxic to the caterpillars, they stop feeding, and die within a couple days.
Applications occur twice, about a week apart. Application normally takes place early in the day when low winds and high humidity allow the product droplets to land on tree tops where they will be the most effective. A management site will typically be finished before children are walking to school or people are heading to work.

People are exposed to Btk through contact with soil in the natural environment or through their diet, at very low levels. If you eat fresh fruits or vegetables, you probably have already ingested this bacterium. It is commonly used on commercial and organic food crops.
There are two parts to the rule. Each part contains separate provisions. Depending on where you farm, you may be subject to one part of the rule, both parts, or neither part.
Part 1: You are subject to Part 1 of the rule if you farm in a vulnerable groundwater area or in a Drinking Water Supply Management Area (DWSMA) that has 5.4 mg/L or higher of nitrate. This means you cannot apply nitrogen fertilizer in the fall and on frozen soils in those areas.
Part 2: You are subject to Part 2 of the rule if you farm land in a DWSMA with elevated groundwater nitrate concentrations. These areas will be designated a mitigation level 1, 2, 3 or 4.

Some people have reported mild skin reactions or mild eye, ear, and nose irritations after Btk treatments. Others have reported mild hay fever reactions. Health officials have studied these reports extensively and have not been able to determine if the reactions were caused by Btk or by pollens, molds, or dust generated during the treatments, or were unrelated to Btk treatments.
Public health officials state Btk is not a public health risk.

Although we don't have evidence that Btk will affect any given group of people, individuals with a weakened immune systems or serious food allergies may choose to avoid any potential exposure by staying indoors during and at least 30 minutes after the treatment or leaving the area during the application.
