Good morning.
My balcony is filled with we cobs. I keep clean it but, in a couple of hours, the cobs show up again. The cobs are not just in the usual spots (eg corners, cracks) they are in between the branches of the plants in my pots (eg dahlias).I've checked and I don't believe there is a colony of spiders that requires disinfestation.
In the internet, everyone has their own method (eg ammonia, mint mixed with water, electronic buzzers). Is there a professional product I can use? Or any other suggestion?
Thank you
