I was in my backyard this afternoon starting to build a fence for my two dogs. I got to a section underneath some pine trees with heavy pine straw on the ground and HOLY MOTHER I've never in my life seen fleas like that. What in the world do I do? I always apread 7 Dust in the yard at the beginning of Spring to help with fleas and ticks but evidently it didn't work. Any one have a sure fire product to get rid of these jokers? And yes when it dries up a little I will burn that pine straw and get some of them, but I'm sure I have them elsewhere in the yard.
