Where do ants have a higher tendency to nest?

Ants typically have a higher tendency to nest in mulch due to several factors that make this environment suitable for their life cycle. Mulch provides insulation and moisture retention, creating a favorable microhabitat that helps protect the ants from extreme temperatures and preserves the humidity levels required for their survival. Additionally, mulch often contains organic matter that can serve as a food source for some ant species, while also providing access to soil microorganisms that can be beneficial for the colony.

While ants can nest in various locations, such as inside homes, in trees, and under rocks, mulch often offers a combination of protection and resources that are less available in those other options. Inside homes, ants may find food and shelter, but the indoor environment is often less conducive for establishing large colonies compared to the rich, communal areas found in mulch beds where colonies can thrive and grow.
