Here's my ant story...we were living in the high desert, very different from what I was used to( the mountains). We would occasionally see little reddish ants that STUNG if they got you. We went away for a weekend, and when we came home, they had invaded the kitchen and dining room, and started to build a nest in the vertical blinds! I got out the spray and started on them - and they started coming after me! I swear this is true...luckily they were only 1/4" long! I finally conquered them, but had the willlies for months whenever I saw even ONE ant!
