Yes, and the floor of the swienty poly hive is designed to provide an 8/9mm entrance across the width of the box.Quite a few of the forum beeks dispense with MG's altogether and incorporate an underfloor entrance design to the hive (UFE), with a max 8-9mm deep entrance no need to faff about each year.
Hi team. I've run out of mouseguards but don't really want to order any more. Any ideas for guards made out of something I can make or buy locally
Try plastic excluder cut ino strips and pin them on the brood box- no worries about queens getting out at this time of the year. OR just use an 8mm x 120mm entrance all year round to keep out the furry "friends". I use a landing flight board too - saves bees falling to the ground on arrival and having to struggle out of the undergrowth fully laden. Basically anything that avoids energy expenditure on the bees part translates to a bigger crop. No worries about over heating in the summer with open mesh floors too.
When I started beekeeping I accepted the advice in places like this and bought MGs. But when I put all my hives on 12" slender high homemade wooden stands on 18" paving slabs and the entrance was well above ground level I chucked the MGs away and have never ever had a problem. Worry about a problem when there is one!!!Quite a few of the forum beeks dispense with MG's altogether and incorporate an underfloor entrance design to the hive (UFE), with a max 8-9mm deep entrance no need to faff about each year.
