Why the bed bugs keep returning
If bed bugs keep returning after treatment, it usually means the treatment was incomplete, neighboring units were not treated, or eggs survived — and the landlord may need to do more, including repeat professional visits and follow-up inspections.
Bed bugs are notoriously hard to eliminate. A single treatment often misses hidden bugs and eggs, and an infestation easily returns from an untreated adjoining unit. Lasting control usually means repeated professional treatments, careful follow-up, and treating the surrounding apartments, not just yours.
When a landlord keeps applying partial fixes that do not work, the ongoing infestation can remain a habitability violation — your home is still not being kept fit to live in. Keep a record each time you report it and each time treatment fails. If bed bugs keep coming back no matter what your landlord does, a free review can help you understand your options.
