The bathroom is almost complete. Apart from a couple of fixtures (towel rails and the like) the only outstanding task is to paint the ceiling.
As you can see, the builders have filled the gaps left by old lights, extractor fans and switches. They also seem to have arbitrarily just placed some plaster on the ceiling … but never mind.
I am a little concerned as I’ve noticed a few dead flies appearing on the inside of the recessed lights. Given there should be nothing up in the attic (especially as we have two cats defending the house), I wouldn’t expect to find anything decomposing above us … leading to flies … or worse … maggots.
The access hatch is lifted and I pull the recessed lights down to remove the flies and also paint around the lights. There is a vague buzzing noise in the loft. I stick by head through the gap with a torch in my hand … but no sign of anything … just the noise.
Things become a little more interesting once I propel some insect spray into the loft … Within five minutes we have a swarm of flies descending into the bathroom.

As they fall to their chemical fuelled death, their final actions consistently involve a rapid spin bearing a remarkable similarity to a winged break-dancer on amphetamines.
Hoovering them up, i spray some more. In fact, i spray so much another visit to the garden centre is required to top up. A couple of hours later I have the blood of over 200 flies on me. And a nose bleed.
I’m still unsure what lies in the attic. Some crazy self-feeding ecosystem of a two year deceased mouse, some flies and maggots I believe. Still, if I spray every week for the next couple of months, I should have interrupted the ecosystem sufficiently to avoid me ever coming across a ball of maggots living above us in the loft space.
