Pulling the window AC units this weekend? Go slow on the first one.
Paper wasp queens and lady beetles like to tuck into the fins and housing of window units in the fall, looking for a dry spot to wait out the winter. Carry the unit into a warm room and they start moving.
What we tell neighbors from Worcester to Hooksett:
- Pull units on a cool morning, when anything inside is sluggish.
- Set the unit down outside first and look over the back and sides before you bring it in.
- Store it covered in the garage or shed instead of a closet in the living space.
