We've tried many kinds of traps and lures, and we have found the Catch-Can dramatically superior to all others. Its double bait system (a floral and a pheremone lure) attracts up to 5 times as many beetles as single bait traps. Reusable collection canister is vented to prevent odors. Sturdy construction guarantees years of service. Extra Bait and optional Metal Stand available separately. Plastic canister holds up to 400 beetles Bait lasts one season
