Long ago, you bought RAID, and it would kill about any kinda bug. So I stop in at Mac's to get another can. Their had RAID for ants, RAID for roaches, RAID for wasps and hornets, and a couple of other things I forget. They did not have plain old RAID for flying insects, which is what I wanted. Give a housefly a whiff of that and their wings stop moving and the bug falls to the floor. They may twitch a little bit, but pretty soon they are dead.
So much for product differentiation.
