Already treated a home for fleas this year. Seems like even the cold icy winter can't keep these disease carrying parasites down. Fleas to me are one of the worst insects. Not only do they inflict pain when they bite you but they can multiply quickly and before you know it Fido, and your family are scratching everywhere! I'm still unsure why God created fleas. I know he has a plan but I'm not sure what these terrible critters have to do with it!- my 2 cents.....
