Can garden vegetables be eaten after applying ant insecticide?

Yes, garden vegetables can be eaten after applying ant insecticide even though there may be a wait between application of the ant killer and harvest of the edibles. The wait is shorter for such homemade organic remedies as boiling water or sprays diluting black pepper, cayenne pepper, chili powder, cinnamon, garlic, hot peppers, lemon juice, mint, pennyroyal, rhubarb, soap, sweet fern or tansy. Baits with the active ingredients of abamectin and of methoprene need waits of four weeks while those with pyriproxfen require six to eight weeks.
