time<\/strong>For the flap to perform its function, it must be installed and lowered in a timely manner.<\/li>\n<li><strong>You'd better buy a protective flap:<\/strong> Manufacturing a protective

She must learn to use the entrance flap after nesting. This is because when she flies out, the nest is not yet fully developed. Without training, there would be a risk that she might abandon it, or while trying to figure out how to get past the flap without training, she would spend unnecessarily long time at the entrance and fall victim to predators (birds). All other bumblebees, guided by the scent of the nest, can already manage with the flap. Making it easier for bumblebees to get through the entrance means opening the door to parasites and reducing efficiency.<\/p><p>You will learn how to get bumblebees to fly into a hive, how to manage them, and how to maintain them during the season in the beekeeping chapters titled \"Season Begins\".\u00a0 <strong>The page dedicated to the use of the flap is <a href=\"https:\/\/www.cmelaciplus.cz\/en\/im-a-flap\/\" target=\"_blank\" rel=\"noopener\">HERE<\/a><\/strong>.<\/p><p>You must also not forget that you must check the flap's functionality <strong>check regularly. <\/strong>\u00a0The landing board can sometimes get stuck, and bumblebees often lose their pollen baskets or wax parts of it on the flap.

The protective flap is the only truly functioning part of the hive that has a chance of stopping a parasite at this point.\u00a0<\/p><p>It must be admitted that even a hive fitted with a flap is not 100% secure. This is because pests have several ways of getting into the hive. <b>The protective flap significantly reduces the risk of parasite ingress<\/b> to the bumblebee nest.<\/p><p>Part of the overlap is attributable to the breeder. <strong>If the flap is to function<\/strong>, the flap must remain closed, the flap must seal against the wooden body, and the functionality of the flap must still be <b>regularly checked<\/b>. <br \/>Sometimes a parasite still manages to get past the flap, but the probability of a successful attack is much lower, and therefore the chances of the bumblebee colony surviving are greater than with hives without a flap.\u00a0\u00a0<\/p><p>Why does that happen?<b>\u00a0Parasites orient themselves primarily by the scent of the nest<\/b> or they watch the returning worker ants and here one must realise the fundamental difference compared to natural nests. <b>Man-made shock<\/b> is an enclosed above-ground space from which odours are released only through leaks and penetrations. This creates for parasites <b>a clear and distinct trail<\/b>, which can be smelled far and wide.<\/p><p>U <b>natural nests <\/b>This is different. Some bumblebee species have nests underground, where the soil acts as an absorber (absorbing scent) and a diffuser (dispersing scent). With underground nests, workers can also adjust the entrance as needed, which isn't possible in a hive; at most, they can close the hive entrance with bedding. Some species have natural above-ground nests, but even there, the dispersal of scent into the surroundings is greater than in the case of hives. A parasite will find these natural nests too, but usually later than a hive, meaning there's a greater chance of breeding and producing sexual individuals compared to a hive. <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28547150\" target=\"_blank\" rel=\"noopener\">Study<\/a> Moreover, they show that most natural nests are destroyed by parasites.<\/p><p><b>Some breeders\/sellers promote their strategy of offering bumblebees as a deterrent and leaving everything to nature \u2013 but we disagree with this approach.<\/b> A sudden fright can thus happen<b> and breeding ground for parasites.\u00a0<br \/><\/b>If we offer bumblebees a nest, we are responsible for them and must look after them \u2013 see the above-described issue of finding a nest by its scent.<b>.<\/b>\u00a0 If we don't do this, the nest will be attacked, weakened, and most likely destroyed before a sufficient number of new queens and males can develop. Whoever wants to leave it to nature can adapt their garden for bumblebees, but it's better not to get a hive as an artificial structure \u2013 then you will genuinely be helping the bumblebees, not harming them. For this reason, hive sellers without flaps are not happy. Their goal is usually just to sell as many hives as possible, and they don't care about the rest.

We have tested the following three and can comment on them.<\/p><p>Currently, the most perfect<strong> Product (A)<\/strong> shown in the picture. It is robust, weather-resistant and, thanks to our group's designed hinge (Uhelon), ensures smooth operation without the risk of jamming. Furthermore, the hinge eliminates parasites attempting to enter the flight opening from above. The polycarbonate flap's canopy is firmly attached with screws to the flap's body.\u00a0\u00a0<\/p><p><strong>Product (B)<\/strong>, as an alternative from which Product (B) originated. The model is widely used. It is by no means a bad product, just outdated in some respects. However, it can be easily modified. <br \/>However, we have recently noticed a problem with the durability of this product, particularly if it has been soaked by rainwater. <br \/>A polycarbonate canopy, cleverly inserted into the flap's body, is a good idea. However, if water gets in here, the flap collapses. Often, the canopy also blows off in the wind, and then it rains directly onto the flap. The older model had an external canopy, which was more advantageous from this perspective.<\/p><p><strong>Product (C)<\/strong>\u00a0The new model of the side flap is inspired by a German design. The model also includes a side trap for catching parasites. It uses the same hinge as Product (A). <br \/>The polycarbonate flap canopy is permanently fixed with screws to the flap body.\u00a0\u00a0<br \/><em>Note: The effectiveness of this trap has not yet been fully verified. However, the flap's function is unaffected by the side trap, meaning it could also be included among top products.<\/em><\/p><p>We do not state specific manufacturers with regard to our Code, but you can find them on the Internet.<\/p><p>The described types of protective flaps are shown in the figures:\u00a0<\/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-7f2c0ee elementor-widget elementor-widget-text-editor\" data-id=\"7f2c0ee\" data-element_type=\"widget\" data-e-type=\"widget\" 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>Some manufacturers use Uhelon hinges on the louvres.

Lid with a separate visor<\/strong><\/p><p>The canopy is mounted on the box above the flap. This solution was used by older models of the Product (B).<\/p><p>When fitting the canopy, position it so that it covers the flap, but at the same time allows the latch to be lifted (ideally fully to a vertical position). .<\/p><p><strong>2. Flap with a hood attached by screws to the flap body<\/strong><\/p><p>If you have a robust slide body, such as Product (A), then a thin polycarbonate roof can be screwed onto the slide body. The roof is thin and flexible, it will flex on its own and water will drip away from the entrance.<\/p><p><strong>3. Flaps with canopies slid into the recess in the flap body.\u00a0<\/strong><\/p><p>The new model of Product (B) unfortunately doesn't have a very well-designed canopy. Although the intention was good (the canopy is easy to remove and slots into a recess in the back wall), the execution couldn't have been adequately tested in practice. Otherwise, the manufacturer would have realised that <strong>Water is entering the groove in the backplate.<\/strong>. It stays there and loosens the backboard. As a result, not only does the roof either not hold or cannot be fitted. There is also a risk of damage to the backboard, which may then not sit precisely on the hive and that is a big problem \u2013 parasites can enter the hive through leaks between the hive and the backboard. In addition, there is overall <strong>Valve deformation and reduced lifespan<\/strong>.<\/p><h5>Solution<\/h5><ul><li>The roof connection needs to be at least temporarily secured. <b>protect against water ingress<\/b>.<\/li><li>We recommend covering this spot with a high-quality <strong>water-resistant textile tape<\/strong> so that water cannot flow under the inserted roof along the back plate.
