A few weeks ago I ate a pineapple in my room and dumped the waste into my wastebin. Then, not having made this experience before, I forgot about that until yesterday when I started wondering about why there were so many flies in here. Seems a fly laid her eggs into the pineapple, and bingo - hundreds of tiny little young flies. I dropped the garbage bag out (most of the flies were in there), but at least a few dozen of those little beasts remained in my room. I swatted maybe a dozen of them with a newspaper (resulting in my window being blotched with reddish-black spots now). That really sucks.
Trying to get rid of them by hanging up glue strips in here now. Seems to work.
Oh, it’s so annoying.
