Use it to control foliage feeding worms, caterpillars, thrips and other listed pests. Natural Guard Spinosad Insecticide can be used on fruiting vegetables, curcurbits, cole crops, leafy and tuberous vegetables, stone fruits, citrus trees and lawns. As an insecticide, Spinosad kills insects both by direct contact and when the insects feed on treated plants, but it's five to 10 times more effective when ingested. One of the benefits of Spinosad is that it has low toxicity to mammals, and it's not toxic to many of the beneficial insects in the garden, such as ladybugs and lacewings. Spinosad should not be applied where bees may be active.
