DIY Wasp 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.
