How do you take this down safely if full and yellow jackets are buzzing around?

Take it down at night.

We suggest waiting until nighttime or the very early morning, when yellowjackets are less active, to handle and dispose of the trap. Firmly press and keep the cap down in the closed position, place in a tied garbage sack and dispose in outdoor household trash. Those allergic to yellowjacket stings should allow others to place and maintain traps for them.

Thank you for your question. Use precautionary measures when taking the Disposable Yellow Jacket Trap down like wearing protective clothing, gloves, or a face mask if need be.
