We have some squatters trying to invade our house right now. BEES. Hundreds of 'em. They are swarming up near a second-story window and about a dozen or so have found a way in through the weep holes at the bottom of the window frame! So I got an oscillating floor fan and set it up on the top stair landing in hopes to discourge them from setting up house in our HOUSE! I squashed six or so, and plugged up one of the holes with some modeling clay. But the other window they are coming in cannot be reached without a very long ladder (it's up at the top of a very high hallway). So there are still a handful buzzing around the hall. They don't seem to be (bee?) concerned about me, thank goodness. This seems to happen to us every year (but usually not this early). The last several years they've tried to invade the garage (sneaking in through the gaps on the side of the door). I managed to deter them the same way... with a fan on full-blast. They don't like it so windy, I guess! Fingers crossed the fan works again!
