A ladybug eats dozens of aphids per day. Aphids drain plant sap and weaken the campus vegetation. By feeding on them, the ladybug keeps plants healthy without any need for pesticides.

Ladybugs are a vital link in the campus ecosystem. They regulate aphid populations in a completely natural way, allowing plants to flourish and supporting other insects and birds that depend on this environment.

What we call weeds are an essential habitat for ladybugs. They overwinter under leaves and stems and find their prey there. TU/e deliberately leaves this vegetation in place as part of its Landscape Vision 2040.
