Back last year I posted that my out buildings were being coated in crap due to swallows nesting. While they are sunning themselves in Africa ... I intend putting in a barrier to stop them this year.
Unless someone has a a better idea, the though is that as the outbuilding is trussed roof construction open at ceiling ... and they nest up in eaves ...
If I put an ant-bird nets horizontal across the joists of the trusses, it will stop them without affecting light passage too much. Probably use a woven 20 x 20mm polyethylene netting ...Now this is where I need help.
Outbuilding is in 2 bays separated by a wall. Would want to fit the netting such that I can still get up into 'roof' space occasionally, where I store materials etc;
So if we take aprox size of each bay as 3.5m x 8.5m ... trusses are right angles to long measurement. looking for suggestions as to how to fix the net, one that it is 'bird tight', so that means fairly taught across the underside of trusses.
Some initial thoughts are thread bamboo canes through the edges and find a way to fix canes (some form of cup hook ?) ... or use canes on ends and down one side, and thread bungee elastic cord down other, allow bungee to hook over some clip at intervals, this would allow access, and 'should help keep net taught.
Maybe even a couple of intermediate canes down centre ?
Anybody got any suggestions ? or better ideas
It only needs to be in place Mar to June I'm guessing ... after which they would have nested elsewhere.
