acceptable wire netting

[jmh33]

I wish to make an enclosure round my fruit trees. What is the size of wire netting required to keep birds out but to allow access to honey & bumble bees?

My fruit cage is netted with 20mm netting- Harrod Horticultural web site gives all info.

Thank you Heather - will use that size
