Do yellow houses attract Hornets, wasps, and yellow jackets?
Thanks for the question. To the best of my knowledge, yellow houses neither attract nor repel hornets, wasps, and yellow jackets. The amount of UV light that is reflected, as well as the heat emitted, from the paint may be a factor in repelling or attracting these insects.
I hope this helps. Please let me know if you have more questions.
I could not locate any data/research studies which show that yellow houses attract these insects. Sugary solutions do attract wasps. Hornets, wasps, and yellow jackets are attracted to their prey of flies, and caterpillers/worm pests.
