Excitement in the Greenhouse

My wasps prefer cool conditions. The ground ones nest under large rhododendrons, and the paper ones will be in a shady tree or under a deck.

I find them very useful. I move any potted plants that are covered in aphids near to a nest, and the wasps clean them up.

I put signs up to warn visitors.

I don't know why we still have not yet had a wasp nest in our greenhouse,
but we did have one just outside the door this year which took a few days to
eliminate in a boxwood shrub. I wonder it if gets too hot in the glasshouse
with temps reaching near 115 deg. F on sunny days?
