Will pouring hot water on yellow jackets kill them?

Pouring hot water on yellow jackets can kill some of them, as the high temperature can be lethal. However, it may not be an effective method for eliminating an entire nest, as many yellow jackets may escape the water. Additionally, this approach can be dangerous for the person attempting it, as it may provoke the insects and lead to stings. For safer and more effective control, consider using pest control methods specifically designed for yellow jackets.
