Fly cemetery and lilac

A few months ago some of my houseplant spider plants had babies and I potted the baby cuttings in some new compost I had bought in a local garden centre. The soil did not look particularly nutritious, but I know there have been bans in recent years in using peat, so I just guessed this was what I had to now deal with. A few weeks later, I noticed tiny little flies ducking and diving all over the house. I also noticed that whenever I watered the spider plant babies, the flies seemed to appear in abundance. I can only assume the fly larvae had been buried in the new compost when I bought it.

I decided to buy some fly-catchers and stick them in the pots I was suspicious of. I then gave the pots a good watering and waited. I then discovered the most horrific sight. There were loads of fly bodies stuck to the catchers. Over the months, the number has increased and occasionally when I am sitting still - such as watching TV or eating, a rogue fly will flutter past me. They are so tiny, you don't really see them coming until they zoom past close to you,  and too fast to catch in my hands. Below is the result of a couple of months since I bought the fly-catchers. Those of a sensitive nature may wish to look away now.

Look to the left side of that last photo, there's a whole cemetery of them. Eugh!

Meanwhile, outside my lilac tree is looking absolutely beautiful at the moment, but is being buffeted by strong winds.
