I'm beginning to note the absence of the big spider that breached our peace treaty not long ago and met her demise early as a result. The big spider is no more—but many varieties of tiny flying things have lately made their appearance in the apartment. Coincidence? Maybe. But these tiny flying things would be a smorgasbord for a big spider, and with no big spider to have them for lunch and dinner, they seem to multiply.
I have some sticky stuff that I got at a little hardware store down the street, and I've hung a strip of it in the bathroom (the flying things seem to like water). It's very effective if the tiny flying things hit it, which they often do. After a few days, there are many cadavers stuck to the strip, testifying to its effectiveness. But I'd be happy to leave these flying things to a resident spider, if one were around to take advantage of them.
I did spy a tiny spider in the bathroom, near the radiator. I didn't disturb it, since it was on its own turf. Hopefully it will collect some of the flying things and make them less of a nuisance for me. It seems like an equitable deal. I provide the bathroom, where there's always a bit of water to attract flies and their ilk, and the spider provides the web that removes the flies from active flying status.
Which reminds me … have you seen the movie Ratatouille? Do you recall the seen in which the rodent protagonists visit a terrifying shop that has dead rats hanging in the window? That shop is not fiction—it actually exists, near the Forum des Halles. I've taken a picture of it to prove it. Indeed, when I saw the movie, I recognized the shop from real life right away. It specializes in methods for killing rodents, but it provides some other pest control products as well.
