Are wall voids (exterior) a good spot to check for bee colonies?

Wall voids, especially in exterior walls, can indeed be a common nesting site for various bee species, including honeybees and bumblebees. These spaces provide a sheltered environment for the colonies, protecting them from predators and harsh weather conditions. As bees often look for protected areas to build their hives and raise their young, wall voids can be ideal locations.

When assessing the presence of bee colonies, checking these voids is essential as it allows for the identification of activity signs such as wax, honey, or bee activity patterns. Identifying these nests early can be crucial for pest management, especially to prevent significant infestations that could lead to property damage or safety issues.

While it may be true that bees can nest in a variety of locations, the nature of wall voids makes them particularly attractive to colonizing bees, reinforcing the validity of the answer.
