I have a friend that has two dogs that use the backyard for their waste elimination. My friend always scoops the mess up but there may be some residual left that he can’t see to remove.
His problems is, that during the summer time he and the wife like to use their yard most evenings but the flies seem to be really agressive to the point of becoming very bothersome.
Do any of you know a way to remove or discourage the fly invasion he is experiencing without using harsh chemicals?
Thanks,
Randal
