This classic glass catcher traps unwanted insects such as wasps, yellow jackets, hornets and flies. Simply add sugar water of fruit juice as bait to lure the pests inside. Pour the liquid through the top of the jar, tilting the jar so the liquid runs down the inside wall to collect inside the lower lip. Wasps and other insects will find their way into the trap through the open bottom. The trap can be placed on a table or hung from a tree or hook. Assorted variety may vary. Sold individually.
