Screening. Place screened enclosures around plants in the cabbage family
to protect against the fly whose offspring is the cabbage maggot.
Biological Control. Bacillus thuringiensis is a bacterium that is deadly

with local nurseries.
Slugs and Snails:

garter snakes, grass snakes, box turtles, salamanders, ducks, and lightning bug
larvae. BE SURE YOU ONLY INTRODUCE NATURAL PREDATORS THAT ARE NATIVE TO YOUR AREA!
Clay Pots. Place overturned clay pots near the shady side of a plant.
Prop up one edge of the pot. Slugs and snails will collect under the pot during
the warmest part of the day. Remove and drop in a bucket of soapy water.

encircling them with the cans, pushing the bottom end into the soil.
