class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4><strong>Why does a guard flap have a latch<\/strong><\/h4><p>The protective flap is based on a principle designed by A. Krenz, improved by M. Stuchl.\u00a0<\/p><p>Bumblebees PLUS have been focusing on protective flaps, as an important element of hive protection, for a longer time and are continuously testing further improvements. We are pleased that manufacturers are gradually adopting them into production and making them available to you.\u00a0<\/p><p>You can read about the flap, its improvements and further modifications HERE (<i>preparing<\/i>)<\/p><p>The basic part of the damper is<strong> Latch<\/strong>. Yes<strong> closes the inlet opening<\/strong>.<\/p><p>If the inhabitants of the hive <strong>They get used to the latch, they lift it<\/strong> They slip under it. The trapdoor then closes behind them.<\/p><p>If they want to get into the hive <strong>Casual visitors<\/strong>, they lack experience, and the catch will put most of them off \u2013 <strong>He can't lift it<\/strong>.<\/p><p>The flap usually deters queen bees that are looking for a nesting site and stumble upon it by chance. It also mostly deters bumblebees, though we have recorded cases where a bumblebee passed through the flap together with workers. The flap effectively deters the greater wax moth (Aphomia sociella), parasitic flies (e.g. Brachycoma devia), etc.<\/p><p>For the flap to provide protection, it must be early <strong>after the nest cell is inhabited by the queen bee, the cover is lowered<\/strong>.<\/p><p>When the mother \u2013 the queen \u2013 is in the solitary phase (before the birth of the first generation of workers), she is quite sensitive to disturbance. Therefore<strong> The flap cannot be started at once<\/strong>, but it has to fold down <strong>to shut gradually<\/strong>. Thanks to this, the bumblebee will get used to the flap within 2-3 days and pass through it smoothly.<\/p><p>\u00a0<\/p><p style=\"text-align: center;\"><span style=\"color: #ff0000;\"><strong>Remember that if you want the hive to be protected from bumblebee parasites, or at a time when queens of later species are looking for nesting sites, the flap must be lowered.<\/strong><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3c73764 elementor-widget elementor-widget-text-editor\" data-id=\"3c73764\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"4\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Here you can see how a bumblebee lifts the flap \u2013 it inserts its head underneath it, then its body, lifts the flap, and slips underneath it,<\/p><p>But they have to get used to it.
