I recently noticed a lot of flying insects around a fuschia bush. Notr sure what they are, they look like thin wasps, without the bulge at the back. Anyway, upon closer inspection I found that they were coming out of a whole near the bush. It's about 8cm big. What can I do about it? Should I chuck something down there, if so what? Should I fill it with soil? should I chuck something down there and then fill it in? Also, when is the best time to do something? morning or evening? If anyone knows of a product I can get could they let me know the name.
I'd like to sort the problem out as quickly as possible. Thanks.
