re: Houseflies outside - how to get rid of them?

In the heat of the day the flies swarm to my porch for shade. I use this stuff and watch the little bastards die within seconds of landing. It contains the same chemical that is in topical flea treatments for dogs/cats so its safe. Lizards and toads clean up the dead flies and I've noticed no ill effects to them. Always get the spot spray... the pellets stain things red when rained on.
