10 Plastic Porter Bee Escapes - Free postage and packing within the UK

• Invented in the USA by Mr. Porter in 1891
• The basic principle of its use is simplicity itself - a one way valve.
• Place the escapes in the crownboard slot/s with the top hole uppermost.
• Check that the stainless steel springs are 3mm apart. This supplies just enough tension for the bees to pass through yet are close enough together to prevent their return.
• Remove the queen excluder and put the crownboard in its place below the super/s to be cleared.
• Bees leave the super, pass through the 22mm diameter hole and into the chamber of the escape.
• Once there the bees have two escape routes through the springs.
• If used properly, bees should clear supers over a 24 hour period.
