Praying Mantis (Tenodera Aridifolia Sinensis) will eat almost any insect, especially caterpillars, grasshoppers, beetles, and other pests. They will also eat roaches. They are carnivorous and feed on any insect small enough to overcome. The egg cases that are harvested are carefully checked to ensure that quality cases are selected for our customers. Attach egg cases to a twig or plant about a foot or two from the ground where there is cover protection for hatchlings. Most cases will consist of 50 to 400 eggs. Release one case per 1500 square feet. Ship Mon - Wed. Available January - June.
