Fleas for Rental Property in Cleveland, Ohio

[Jared Smith]

All - I've owned this rental property for +6 years in Cleveland, OH and never had fleas ever with several rental cycles. No carpet and fully renovated. Newer tenants got fleas. I am paying for all treatments, but they are asking for rent reductions etc. after legal advice from a connection they have that has been giving them legal advice. Curious on ideas for resolutions? 3rd treatment within 30 days today and no way to prove on either side who or what caused the fleas. Thanks in advance!
