Vector Fruit Fly Traps are designed to help pinpoint fruit fly breeding sites. Once identified, the most effective means to eliminate fruit flies is to eliminate the breeding site through good sanitation. The patented attractant in these traps will result in quick catch of fruit flies. The 960 Vector Fruit Fly Trap is scientifically designed to capture Drosophila fruit flies. To locate the source or sources of a Drosophila infestation through monitoring the count in the trap. Drosophila require very little debris for successful breeding sites. The 960 Vector Fruit Fly Trap is designed to attract adult fruit flie s from short distances and, by counting and mapping infestation levels, to pinpoint specific sources of infestation. Place the traps in areas where Drosophila have been seen. Place the traps where they will not be disturbed or tipped. Avoid placing traps over food preparation areas or exposed food to minimize fruit fly activity and attraction in this area. These areas also have a high degree of human activity, which increases the chance that the trap will be tipped or knocked out of position. Use supplied glue dots to secure the trap in place. Remove the lid to count the number of adults in the trap. If there are a large number of captured flies in a single trap, you may want to strain the liquid for ease of counting. Record trap counts on a site map. Discard traps after 30-days of use and replace with new traps. Traps are most effective when placed near breeding sites. Place behind or under bars, beverage centers, dishwashers, food displays, food service islands, sinks, ovens, supply racks, vending machines, food preparation tables, etc. NOTE: Drosophila will gravitate toward decaying food odors so it is important to discard all food peels and food materials to minimize fruit fly activity in production areas.
