Neighboring house problems

[Claudia Ho]

The house right next to my rental has a rat problem where it doesn't seem to have an active landlord/property management taking care of the property. The rats are going over to my rental which my tenants are complaining. I've hired a rodent company to take care of things but still, neighboring rats are still coming over. The house next door is owned by an LLC and I already tried to locate the owner to the house the LLC is registered under but no luck. Anyone have any other ideas?
