Forum Thread: What Wire Mesh Size Will Allow Pollinators Through but Exclude Rats from Eating Fruit?

Rats have eaten most of our berries, beans and tomatoes this year. They preferred these over bait. I built a 1/2" mesh hardware cloth cage to save remaining tomatoes but did not observe any further fruit development; I wonder if bees avoid this mesh and if so would 1/2" mesh 'chicken wire' be more bee friendly.
