Because of their similar shapes, wasps and bees frequently get mixed up. Bees, however, have a less distinctive light brown/yellow colour. In contrast, wasps have conspicuous yellow/black stripes across the abdomen. Also, because they are social insects, honeybees’ dwell in nests that can include thousands of workers.
If you are unsure whether there is a wasp's or bee's nest, carefully inspect the brickwork to determine whether they are entering or exiting a single hole or air brick. Wasps will have only one hole, while mortar bees will inspect multiple.
Honeybees are gentle creatures. They die due to stinging and swarms in either spring or summer. At the same time, wasps have an aggressive personality. It stings frequently and easily. Also, common in late summer but does not swarm.
