Sevin Dust

Unlike that, sevin dust is systemic. The spray kills bugs without getting into the vegetables’ skins.

Ready-to-Use Sevin, 5% dust, is made to kill over 65 different kinds of insects, such as Japanese ladybirds, spider mites, leafhoppers, webworms, fleas, arachnids, and earwigs.

Sevin dust is recommended for lawns, gardens, fruit trees, and other plants outside. Due to the low levels of exposure, Sevin dust shouldn’t pose any major health risks, including cancer risk, to people.
