in a hive even without attractants \u2014 if you follow our instructions.<\/li>\n<li>\n<p>Natural attractants work best: bumblebee queens are most attracted to the smell and microclimate of abandoned vole nests and natural cavities.<\/p>\n<\/li>\n<li>\n<p>Fine rabbit fur and clean vole nests are excellent attractants for the buff-tailed bumblebee (Bombus lucorum) and related species.<\/p>\n<\/li>\n<li>\n<p>Dog hair can also work: but only the fine fraction and only from a dog without antiparasitics and perfumed shampoos.<\/p>\n<\/li>\n<li>\n<p>Part of the old lining is useful \u2013 attractants from last year's nest must be free of any residual parasites.<\/p>\n<\/li>\n<li>\n<p>A lavender hedge after one season helps.<\/p>\n<\/li>\n<li>Scientific studies confirm the importance of scent: mothers seek out areas frequented by small mammals.<\/li>\n<li>\n<p>A natural attractant is not just a smell, but also a microclimate: stable temperature, dryness, dim light, and protection from the wind.<\/p>\n<\/li>\n<li>\n<p>The surrounding environment plays a big role: bumblebee queens prefer nests located in mosaic landscapes, on forest edges and close to spring food.<\/p>\n<\/li>\n<li>\n<p>There is no \u201emagic scent\u201c: no single synthetic chemical attractant works reliably.<\/p>\n<\/li>\n<li>\n<p>The best attractant = a combination of organic odours, a good nest site, but also correct nest preparation and queen settling procedures.<\/p>\n<\/li>\n<li>\n<p><strong>Don't look for one magic bullet, but solve all the necessary

foundation of success when establishing bumblebees is<\/strong><\/h4><p>New beekeepers often ask us how to increase the success rate of bumblebees establishing in a hive.<\/p><p>If you read our guides, you'll learn that success isn't down to one magic bullet\/factor, but rather a combination of details that work together as a whole, but don't work in isolation:<\/p><ul><li>The breeder must have a good trick up their sleeve<\/li><li>The shock must be placed in the correct place and at the correct time<\/li><li>The enclosure must be properly prepared and have good littering in sufficient quantities.<\/li><li>The breeder can leave it to nature whether the bumblebee mother finds him herself.<\/li><li>If the breeder is actively settling the mother, it must be a mother who is herself looking for a nesting place, is ready for it, and is not already nesting elsewhere.<\/li><li>The breeder can actively offer the doe a scare, but this must then be done very gently, quickly and without stress or transport \u2013 see our recommended procedures.<\/li><li>The mother doesn't have to settle down straight away because she's not ready, the surrounding conditions, or the weather isn't

Therefore, they are not looking for what seems like a \u201cdetail\u201d that they are not doing correctly, and thus are unsuccessful. They are even more so looking for that \u201csomething\u201d that could help them in their first season.<\/p><p>Our experience confirms that if a beginner breeder sticks to our basic procedures, then with a little luck, they will succeed.<\/p><p>Attractants that suit some species of bumblebees may not suit others.<\/p><p>For example:<\/p><ul><li>The buff-tailed bumblebee (Bombus terrestris) likes to seek out burrows left by small rodents.<\/li><li>The garden bumblebee (Bombus hortorum) likes to nest in abandoned bird nests.<\/li><li>The bumblebee (Bombus pascuorum) gets by with a bit of old grass (last year's grass), moss, etc.<\/li><\/ul><p>That's why we don't believe in or promote any universal spells, because we don't use them ourselves.

It tested a synthetic mouse excrement scent as an attractant for bumblebees. The study shows that bumblebees can detect the scent of mouse nests and that this can increase nest occupancy. However, this is new research, not something written by D. Goulson (see above).\u00a0<\/p><p><strong>Abstract <\/strong><\/p><ul><li>The protection of bumblebees primarily focuses on supplementing floral resources. However, the availability of nesting sites is also closely linked to bumblebee abundance. As a supplement to natural nesting sites, artificial nests can be deployed and furnished with synthetic lures.<\/li><li>Because bumblebee queens are reported to establish colonies in abandoned rodent burrows, we hypothesised that bumblebee queens can perceive and behaviourally respond to rodent odour, and that baits with synthetic rodent odour can guide spring queens into nest boxes.<\/li><li>We collected volatile substances from bedding contaminated with urine and faeces from laboratory mice (Mus musculus) and identified 10 odorants that elicited responses on the queens' antennae.<\/li><li>To test the attractiveness of mouse odour to queens in the field, we placed pairs of nest boxes on trees in flower-rich locations and, in each pair, inserted clean bedding into one box and mouse-soiled bedding into the other.<\/li><li>The queens established colonies in 17 boxes with a mouse scent and in six boxes without a scent. This 43% occupancy rate for boxes with a mouse scent represents a significant improvement compared to the approximately 10% occupancy rate typically seen in unscented boxes. In a further field experiment, we filled one nest box in each pair with synthetic mouse bait and found that the queens established colonies in 13 baited nest boxes and in six control nest boxes without bait. In particular, Bombus mixtus established seven colonies in baited nest boxes and only one in an unbaited nest box.<\/li><\/ul><p><strong>Key findings<\/strong><\/p><ul><li>Bumblebee queens (Bombus spp.) can detect and react behaviourally to the scents of mouse urine, faeces and fur.<br \/>\u201eIn GC-EAD analyses, 10 headspace odourants of soiled mouse bedding elicited antennal responses from queen\u2026\u201c<\/li><li>Mice droppings significantly increase nest occupancy \u2013 roughly threefold compared to controls.<br \/>\u201eEighteen (43%) of the mouse-scented nest boxes were occupied, whereas only seven (17%) of the unscented boxes\u2026\u201c<\/li><li>A synthetic lure that imitates the smell of mice also increases occupancy, although less than natural material.<br \/>\u201eQueens established colonies in 13 baited boxes and in six unbaited control boxes.\u201c<\/li><\/ul><p><strong> What the study doesn't say<\/strong><\/p><ul><li>It does not address whether bumblebees prefer the scent of a specific rodent species (only *Mus musculus*).<\/li><li>It does not investigate whether the scent works in underground enclosures (the experiments were conducted on trees).<\/li><li>It does not address the long-term impact on colony success (all were destroyed by the greater wax moth).<\/li><\/ul><p><strong>Bumblebee PLUS Note<\/strong><\/p><ul><li>The study focused on the olfactory attractant, not on the influence of other parameters and conditions such as fright, etc.<\/li><li>In our opinion, the outcome would have been different if the cells had been correctly prepared \u2013 but we do not underestimate the influence of the attractant<\/li><li><strong>Our recommendation remains the same \u2013 the smell of urine and droppings from small rodents is not enough on its own for the successful occupation of a bumblebee nest.<\/strong><\/li><\/ul><p><strong>Source<\/strong><\/p><ul><li>Rodent odour bait: A new bumble bee conservation tool to enhance nest box occupancy (2023).<\/li><\/ul><p>The attached image illustrates the procedure used in the project. <strong><span style=\"color: #ff0000;\">\u00a0<\/span><\/strong><\/p><p style=\"text-align: center;\"><strong><span style=\"color: #ff0000;\">If you want your nest to smell good and not stink, we definitely do not recommend this solution!\u00a0<\/span><\/strong><\/p><p>\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-94a1d52 elementor-widget elementor-widget-text-editor\" data-id=\"94a1d52\" 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<div id=\"attachment_36940\" style=\"width: 752px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-36940\" class=\"wp-image-36940 size-full\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2026\/03\/Cmelaci-PLUS-Rodent-odour-bait-A-new-bumble-bee-conservation-tool.png\" alt=\"Bumble Bees PLUS - Rodent odour bait - A new bumble bee conservation tool\" width=\"742\" height=\"516\" srcset=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2026\/03\/Cmelaci-PLUS-Rodent-odour-bait-A-new-bumble-bee-conservation-tool.png 742w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2026\/03\/Cmelaci-PLUS-Rodent-odour-bait-A-new-bumble-bee-conservation-tool-300x209.png 300w\" sizes=\"(max-width: 742px) 100vw, 742px\" \/><p id=\"caption-attachment-36940\" class=\"wp-caption-text\">Illustrative image from study<br \/>Source: Rodent odour bait \u2013 A new bumble bee conservation tool<\/p><\/div>\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-be9de3b elementor-widget elementor-widget-text-editor\" data-id=\"be9de3b\" 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<h4><strong>What doesn't really exist and what not to look for<\/strong><\/h4><p>\u274c no known universal chemical that reliably \u201eattracts\u201c a mother from a distance<br \/>\u274c No verified synthetic pheromone<br \/>\u274c No simple commercial scent that works universally<\/p><p><em><strong>Source:<\/strong> <\/em><\/p><ul><li><em>Orlova &amp;
