Walking sticksÂ are usually brown or dark green and about 60mm (about 3″) long. They have long thin, sticklike bodies and long thin antanae. Camoflage is their greatest asset.Â

Diet and Damage
They attack cherry trees, oak and other hardword trees. They are not usually very harmful but severe infestations may occur. They can defoliate trees. Nymphs feed on the leaves and eat the entire leaf except the hard veins. They are interesting to watch if you do happen to spot one.
Birds are a natural predator of the walkingstick. Put up bird houses in the affected trees.
2) Hand Pick
If you can spot them that is. Drop them in hot soapy water. I only recommend this if you have a severe problem as they rarely do major damage unless en masse.
