• Use this trapping method where students cannot gain access to the traps or at a time when students are not in school.
• Mix the fly bait according to the instructions in IPM for Flies in Schools.
• Set up the fly trap with the fly bait in the area where the yellowjackets are a nuisance.
• If after a day or two the trap is still attracting only flies, move it to a new spot around the perimeter of the nuisance area.
• If your trap stops catching yellowjackets, but is still catching flies, try switching to a sweet bait such as fruit punch, jam, or grenadine.

Note:: To avoid being stung, you should replenish the fly bait or move the trap during the coolest times of the day. To kill everything in the trap before emptying, put the trap into a large plastic garbage bag and seal the bag. Place the bag in direct sunlight for several hours or in a freezer overnight.

Cone Trap. Bait Pan is placed beneath the cone. Make sure the top edge of the bait pan is above the bottom edge of the trap. Top is also made of screening. Top should be hinged (to empty the trap) and closed with a hook and eye. Weather-stripping or a strip of foam or cloth glued to all four sides of the underside of the lid will prevent flies from squeezing out.
