Demon WP is not specifically labeled to treat tussock moth caterpillars.
We found an article by the University of California Ag Extension Office explaining how to treat and prevent these pests.
The article states, “Bacillus thuringiensis (Bt) is known to control tussock moth larvae, especially if applied when most larvae are young. Bacillus thuringiensis kills only caterpillars (butterfly and moth larvae) that feed on sprayed foliage. A second application of Bt about 7 to 10 days after the first is recommended because of its short persistence.”
