This method has been used in conjunction with porter escapes
to allow the beekeeper to permit the return of bees by an
uninterrupted path. This is mainly so that 'wet' supers that have been
extracted can be returned to the bees for cleaning up.
The blade that closes the hole has been made from tinplate
in the past, but the ones we used to make at Apex Enterprises had anodised
aluminium slides. The slot and area that the blade slides over are
treated with
Petroleum Jelly so that any
propolis, that the bees try to apply, will not stick.
