Success! Earwigs trapped.
An easy recipe for keeping insects away from plants
We imagine there can't be many gardens that haven't been invaded by snails or slugs, earwigs or roly polys. Many gardeners just turn away in annoyance, and sacrifice some of their harvest. But there are easy ways to fight back.
At LA Green Grounds, founder Florence Nishida made bait that appealed to the bugs' natural attraction to the smell of fermentation: a bit of vegetable oil and a bit of vinegar or soy sauce in an open-top shallow can, such as cat food or tuna. The oil keeps the insects from swimming on the top of the liquid and climbing out of the can.
If you water, watch for the traps, so you don't spill the contents out onto your plant beds. And move the can to various locations, best near the base of a chewed-up plant, or in the corners, or under the shade of large leaves.
Most of these invertebrates stay sheltered during sunny days, and come out and feed in the evenings.
When your trap is full, discard and refill it with the bait if necessary.
