Unscrew the cap. Then, flip the top of the bottle upside down, and tuck it into the bottom portion of the bottle to complete your wasp trap.
How to Bait Your Trap:
Different baits work at different times of the year. In the spring and early summer, wasps are looking for sources of protein. In the late summer and early fall, wasps are looking for sweets. To successfully bait your trap, stick a piece of lunch meat or a small hunk of hamburger inside your trap in the spring. Use a few inches of soda, juice or another sweet liquid in the summer and fall months. Add a bit of vinegar to the mix to keep bees out of your trap.
How to Set Up Your Trap:
Place your trap (or traps) outdoors in areas where you see wasp activity (or are trying to prevent wasp activity). If you're trying to keep wasps away from your picnic, set up a bottle a short distance from the table, so they'll hopefully be attracted to the trap, instead of your food.
Prefer a hanging trap? You'll find instructions for that on the next page.
How the Wasp Trap Works:
Wasps are attracted to the scent of the bait, and fly into the bottle opening to get to it. Once inside the bottle, they can't figure out how to get back through the narrow opening, and eventually die, drowning if liquid is present.
Maintaining Your Trap:
Remove dead wasps from the trap regularly, and rebait the bottle at least once a week, so you continue to attract wasps.
A Word of Caution: Always exercise care when dealing with wasps, and avoid contact, if you're allergic.
