Hello everyone. I'm hoping that someone here can help me out with some advice on what to do about my overpopulation of squirrels. I live in a house converted to four flats in West London, with four little gardens round the back, and we are overrun with grey squirrels. Now they're very cute and good fun to watch, even if they do trash the gardens like mini wild boar. However it's not become apparent that they are also running wild under the roof, keeping the guys upstairs awake at night, and worse than that, they've been chewing through electric cables. So we're going to have to proceed with a violent eviction. The garden's not really suitable for using an air rifle as it backs onto a school. I was thinking of using a cage trap and dispatching them with my air pistol. That's simple enough, but how to I shift them out of the roof? We're at the end of a row of terraced houses and I don't think that from a squirrel's perspective, there's any separation between our roof and the neighbours'.
We're also about to have some repair work done on the roof. Is there anything that can be done to block the creatures' access? I realise that realistically, we're just talking about a cull, there will always be an influx of them, and I wouldn't want to eradicate them anyway, I quite like them. But I can't have them damaging the roof and electrics.
Thanks for your help!
