Roll up a page of a newspaper in the shape of a cone. Keep the paper tightly rolled at the pointed end so the earwigs can’t escape, but open in the other end so they can crawl inside. Secure the paper with a rubber band. If you have an old garden hose, cut it up into 12-inch lengths. Make several of these to place throughout the garden.
Place the newspapers between the plants. The earwigs will enter the newspaper or garden hose as night is ending.
Check the newspaper or hose traps each morning. Unroll the newspaper or tap them against the side of the container to dump the earwigs out and into a bucket filled with soapy water.
Smear the stems of your vegetables with petroleum jelly. You don’t need much. Petroleum jelly that is the width of your finger is sufficient. The earwigs won't cross over the petroleum jelly.
Find plastic containers, making sure each container has a lid. Old sour cream containers work well for this.
Mix together equal amounts of soy sauce and olive oil in each container.
Punch holes in the top of the lid that are big enough for the earwigs to crawl through.
Dig holes around your garden between plants or anywhere the earwigs are a problem. The holes should be wide enough for the container.
Bury the container so that the soil is level with the holes. The soy sauce attracts the earwigs. When they crawl inside the container, the oil traps them.
Check the soy sauce and olive oil mixture every day and change when needed. Dump the contents into a garbage bag. Tie the bag shut and leave out for garbage pickup.
