Spectracide Bag-A-Bug Japanese Beetle Trap Replacement Bags are designed to be used with Spectracide Bag-A-Bug Japanese Beetle Trap (sold separately). These bags have an hourglass shape that traps thousands of beetles per bag, preventing them from escaping and limiting your contact with the beetles. These disposable replacement bags can simply be sealed and thrown away (see product labeling for details). This carton contains 6 replacement bags. A constant source of aggravation for gardeners, Japanese beetles eat 300 types of trees and plants. Metallic green with coppery brown wing covers, these 3/8 inch-long creatures are often found around homes and gardens. Spectracide Bag-A-Bug Japanese Beetle Trap2 uses a dual lure to draw Japanese beetles away from valuable ornamentals, flowers and shrubs. This lure contains natural pheremones, together with a proven floral lure, to attract two to five times as many beetles as the commonly available floral lure alone.
