The grass in my apartment complex is INFESTED with fleas! I have my dog on frontline, sentinal tabs, and a flea collar and he STILL bring them in from outside. Now they have infected my indoor cat. I bomb the place once a month and give them flea baths at the groomers but nothing stops them because they don’t protect the lawn! Is that even legal??? What am I supposed to do? Any advise would really help. Thanks!
