One of my nightmares is coming true. Creatures are coming out of the wall.
Last night I noticed a few more flies in the hall. I have no mercy for flies and would have fogged the whole house if necessary, but these seemed especially easy to catch. They were flies that didn't fly. They didn't even crawl very fast.
This morning they were covering the door to the laundry room, dozens of them. I swatted the ones I could reach, and there were so many that I tried to vacuum them off the rug. That was a big mistake, because all I did was smear fly blood on the white carpet.
So I began picking them up with paper towels, but every time I turned around more flies seemed to be materializing out of the air. Some of them flew off, but most were merely ambulatory.
Finally I couldn't take it any more and got out the Raid. The special Raid for flies. I sprayed it in the laundry room and shut the door, then sprayed along the baseboard and door jamb. Soon I had many dead flies in the hall, which I consider an improvement over the live ones.
I cleaned them up, and then cleaned up the later arrivals. By this evening I considered the invasion to have been halted. If there are no new bodies in the morning, I'll call the campaign a success.
