well-known bumblebee guru (sadly now in bee heaven), designed and described ventilation with a parasite trap.&nbsp;<\/p>\n<p>This solution has evolved into several variants which we describe. As the Bumblebee PLUS group, we are paying attention to this important part of the hive (bumblebee house) because a good solution will significantly reduce the threat of parasites entering the hive.<\/p>\n<p>We are also pleased that some manufacturers have heard us, have adjusted the ventilation openings according to our recommendations (UHELON53S and aluminium mesh) and that these adjustments serve you well.<br>Although we are not listed as the largest manufacturer of bumblebee boxes in the Czech Republic, they use these solutions, and that is what matters. Other manufacturers use them too, so bumblebee boxes are gradually improving. <br>Our improvements are not protected by copyright and we make them available for free. We consider crediting the authors to be a courtesy and are pleased that at least some manufacturers consider this to be normal.<\/p>\n<p><\/p>\n<h4><strong>Ventilation principle with parasite protection<\/strong><\/h4>\n<p>The principle proposed by Mr. Miroslav Stuchl is that the best way to ventilate a hive is to create a tube that connects the inner space of the hive with the surrounding environment.<\/p>\n<p>Seal the tubes at the ends with a mesh\/net so fine that even small worker bumblebees cannot pass through it.<\/p>\n<p>You will fit the netting on the outside (outside the hive) with an opening and insert a tube (straw) into it. It should be large enough for the parasites seeking a way into the hive to pass through. The internal netting will stop the parasites that enter the hive. Thanks to the tube in the external netting, they will not find a way out.<\/p>\n<p>Mr. Stuchl also described the possibility of using bumblebee honey as an attractant and at the same time as a glue for small larvae inside the trap.&nbsp;<\/p>\n<p>The original design was described in the book \u201eKeeping and Supporting Bumblebees in Gardens and Towns\u201c (by a collective of authors), and we present it here with the author's permission.<\/p>\n<p><\/p>\n<div id=\"attachment_4977\" style=\"width: 360px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-4977\" class=\"wp-image-4977\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2020\/02\/Cmelaci_PLUS_Ochrana_vetrani_Stuchl-scaled-e1582403521582.jpg\" alt=\"Bumblebees PLUS - Ventilation Protection according to M.

Jarom\u00edr \u0106\u00ed\u017eek came up with this solution.\u00a0 <br \/>This causes the parasite, which enters the ventilation, to get caught on the sticky layer. Likewise, small parasite larvae, which hatched from eggs laid on the ventilation mesh, will also get caught here. <br \/>Pavel Fere\u0161 reached the same solution, Jarom\u00edr \u010c\u00ed\u017eek uses a similar one.<\/p><p>Thanks for finding<strong> technical mesh with the correct mesh count<\/strong> (<strong>UHELON53S<\/strong>the ventilation safety was further increased.
