How do I protect hummingbirds from an application of Natural Guard Caterpillar Killer Spray with Bt?

Answer:

Natural Guard Caterpillar Killer Spray with Bt contains naturally occurring bacterium found in soils throughout the world that is not labeled to harm songbirds, other birds, wildlife or beneficial creatures when used as directed on the product label.  It is best to apply when they are not in the area and hope they do not return until dry.  Once the product has dried, it only has a toxicity level of that to kill something as small as an insect, and only those specific insects on the label.
