Don't worry , been down the apiary today, +9C, not a single bee flying , checked fondant , bees chomping merrily away, two or three corpses outside one hive !my hive not been that active yet, was one bee out on sunday, wandered back in when i arrived. Should I be worried that they are not more active? everyones hives seem to be so busy.
Heard that before and it is utter bo***cks. Check the size of a mouse's skull and it is bigger than a pencil. The test applies where the beast can get its jaws round something and can then chew it larger - and for that a pencil size is indeed probably big enough - but when the hole is in a metal strip I suspect the average mouse would find it a little hard to enlarge the hole.Standard industry pest test is if you can put a pencil through it then a mouse can get through.
