Rent reduction for bedbugs, cockroaches and other insects

6 rulings on this topic – with reduction rate, case number and link to the decision.

Updated: October 2026 · 119 court rulings

A serious insect infestation is a defect when it goes beyond what occurs in any apartment. On bedbugs, the Stuttgart local court ruled that bringing them in with luggage is part of normal use of the apartment and does not rule out a reduction (35 C 5509/19).

The amount depends on the type and extent: a few silverfish justify very little, a massive infestation or an apartment that is uninhabitable because of the pest control chemicals a lot. Report the infestation in writing straight away and allow pest control in.
