Under Floor Ventilation

I've seen "pits" down the side walls of houses with a conventional vent in the wall 6" or so down. Older houses mind, but as long as the pit cannot fill with rainwater, it's a solution.

We have those. The exterior ground levels are well above damp course so I put a pea gravel french drain round the entire house. The suspended floor vents are protected by concrete edging. They gather a few leaves but not much of a problem.

Whatever you do about things like damp courses, for goodness sake fit a fine mesh over them. I have found wasps love to live under your floors, even better if there are nice warm pipes under it and of course its a sod of a job to remove the nest without ruining the floor. Bah humbug. Brian

You don't need to remove the nest as such. All you have to do is spray the air brick or whatever, where they're getting access, with a foaming wasp killer, and as they come and go, they carry it into the nest and the occupants all die within a day or so. Then the nest itself just dries out and decays over the next few months or years. It's only made of paper, after all.

Maybe so but a load of decaying dead wasps are not a nice thing to think about under your floor! Brian

Almost anything is not nice to think about when you're stuck under your floor.

It can be quite restful down there - a few minutes' break, in the quiet, while you've sent your son off to fetch something to save yourself from having to crawl out.

what a stupid idea ...

Yes well, since the system does not seem to quote either, even if they intoned it to be that way, it makes no sense at all outside of Howme owners hub. sigh. Brian
