Strawberry netting

What size/type nets do people use? I have just finished putting my anti-bird frame over the strawberries and I noticed the net I used last year will only admit small bees! I have some lovely big Bumbles flying around and don't want to deter them. Haven't seen a lot of hive bees though.

 

Liz, if it was a success last year then it will be this time. It wont stop the bumble bees coming into your garden, so don`t worry.
