Spectracide Bag-A-Bug Japanese Beetle Trap Replacement Lure is designed to be used with Spectracide Bag-A-Bug Japanese Beetle Trap (sold separately). The dual lure draws Japanese beetles away from valuable ornamentals, flowers and shrubs, helping to protect roses, grapes, fruit trees and vegetables. This lure contains natural pheromones, together with a proven floral lure, to attract two to five times as many beetles as the commonly available floral lure alone. Under normal conditions, one lure is effective for about 12 weeks; replace it after this period or when its floral aroma is no longer noticeable. This carton contains 1 replacement lure. 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.
