agricultural use. For non-food use only.  Do not hang trap if you are allergic to wasp, hornet or yellowjacket stings.

Initial Setup

1. Remove twist-tie and enclosed Attractant Vial and green Attractant Tube from 

top chamber.

2. Remove yellow Attractant Tube and felt pad from bottom chamber. (Leave 

cone in place.)

3. Bait the bottom chamber first:

a. Place felt pad into center of bottom cap.

b. Cut tip of yellow Attractant Tube.

c. Carefully empty attractant liquid onto felt pad.

d. Screw bottom cap back in place.

e. Set trap on flat surface.

4. Next, bait the top chamber:

a. Remove Attractant Vial from its plastic pouch. 

b. Pop open lid to Attractant Vial and snap into one of three notches next to 

the cone in the top cap. (Figure 1)

c. Cut tip of green Attractant Tube and carefully pour liquid into top chamber.

d. Add water to top chamber so solution reaches the Start Line. Add 1-2 

drops dishwashing liquid to the water mixture.*

e. Thread twist-tie through hole on top cap.

f.  Screw top cap back on and hang trap outdoors. (Figure 2)

5. Wash hands with soap and water.

Trap Placement:

1. Hang trap outdoors, at least 20 feet away from plants grown for food or feed, 

building entries, and any known wasp, hornet or yellowjacket nests. Hang 

traps in late evening or early morning when wasps, hornets and yellowjackets 

are less active.

2. In extreme hot and dry weather, hang trap in the shade.

Top Chamber:

*Adding dishwashing liquid to the water mixture in the top chamber will coat the 

insects’ wings and make it harder for them to fly once trapped. 

In hot and dry weather, liquid level in top chamber may evaporate below the 

Start Line before the attractant is due to be replaced.  Do NOT add additional 

water to bring the liquid back up to the Start Line, as it will reduce attractant 

effectiveness.

Use Rate:

Use 2-4 traps for a 10,000 square foot area, or 8 to 16 traps per acre. For 

areas with heavy infestation, use a maximum of 48 traps per acre.

Reusing the Trap:

The attractants in the W·H·Y

®

 Trap are designed to last 2 weeks. W·H·Y

®

 

Attractant Kit refills, which last an additional 2 weeks, should be available for 

purchase wherever the W·H·Y

®

1. Check to make sure all trapped insects are dead.  

2. Empty dead insects and wipe insect residue from trap. (Top chamber cannot 

be emptied of insects without replacing the attractant.)

3. Follow directions for baiting the bottom and top chambers in the initial setup 

instructions.

Catching the Queens:

Wasp, hornet and yellowjacket queens hibernate during the winter, then 

emerge to look for nest sites.  Paper wasp queens are the first to emerge, 

usually in late winter.  Hornet and yellowjacket queens emerge later, during 

the first warm days of spring.  When you use the 

W·H·Y

®

 Trap

 at that time, 

you can capture some queens and reduce the likelihood that a nest will 

be established nearby. Insects caught this early in the season may not be 

numerous, but each queen captured represents one less nest later on. Once 

queens begin nest building, the W·H·Y

®

 Trap may have periods of lower 

catches until worker populations grow.
