Bees in the yard...am I responsible?

[Denny Bernacki]

Tenant was stung by a bee or wasp in the yard and is requesting owner to treat the yard.  Our lease does not specifically address responsibility for yard bees.  As a renter I would simply grab some wasp spray....use it...and move on.  Is this something a landlord needs to (or should) entertain.  I have always assumed tenant responsibility for pest control unless otherwise specified.
