I have a permanent greenhouse for Herbs and flowers. It has evolved successfully with the addition of fans to draw in outside air and circulate the air in the California Central Valley heat. I leave the roof vents wide open. This year I had a paper wasp nest and foraging honey bees come inside. Wasps and bees do not seem to bother each other. The bees want the Basil flowers, and the wasps patrol the vegetable garden around the greenhouse. Sometimes misguided residents in my neighborhood spray flying insect killer outside and there is a temporary population reduction in butterflies, bees, and wasps. the wasps have the hardest time since they have to feed growing young wasps.
