Trap slugs and snails in pie plates buried to ground level and filled with beer. Another alternative is to use parasitic nematodes for fleas. Keep children and pets off treated areas until the material is washed into the soil and the grass is dry. It is toxic to fish, shrimp, crabs, birds, and other wildlife and has been implicated in numerous wildlife poisonings, including those of robins, pigeons, and Canada geese. Also try ladybugs for aphids, insecticidal soaps and superior oil for whiteflies, milky spore disease for Japanese beetle grubs, and Beauvaria bassiana fungus for chinch bugs.
Nematodes can be effective on a variety of grubs, beetles, grasshoppers, and other insects.
It's commonly sold as light- brown granules. Diazinon can be harmful to humans if swallowed, inhaled, or if it contacts the skin, and is highly toxic to birds, fish, and other wildlife. Similar events led the EPA to ban its use on golf courses and turf farms, but homeowners can still buy it. Nearly half of all reported wildlife poisonings from home or garden pesticide use involve diazinon. It is absorbed by ornamentals, fruits, and vege-tables for residual protection from these insects for days to weeks.
