These harmful insects feed exclusively on human blood, and their excrement, composed of digested blood residue, leaves characteristic traces.<\/p>\n\n\n\n<p>Here&#8217;s how to identify them:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Appearance:<\/strong> Droppings appear in the form of small black or brown spots, similar to ink blots. They are usually clustered near areas where bedbugs hide: <a href=\"https:\/\/www.sereni-d.com\/en\/our-advice\/bedbugs-in-the-mattress-inspection-and-processing\/\">mattresses<\/a>, box springs, the seams of sheets or skirting boards.<\/li>\n\n\n\n<li><strong>Location:<\/strong> Look for these marks around mattress seams, on pillows, in the crevices of the box spring, or on furniture close to the bed. These stains can also be found on walls or behind the headboard.<\/li>\n\n\n\n<li><strong>Texture:<\/strong> Excrement is dry and spreads slightly when rubbed with a damp cloth, leaving a brownish mark.<\/li>\n<\/ul>\n\n\n\n<p>The droppings are often accompanied by dead bedbug skins or whitish eggs. These are very revealing signs of an infestation.<\/p>\n\n\n\n<p><strong>Practical tip:<\/strong> If you find these marks, don&#8217;t ignore them. Vacuum the affected areas immediately, then use a high-temperature steam cleaner (minimum 100\u00b0C) to decontaminate thoroughly, and apply our <a href=\"https:\/\/www.sereni-d.com\/en\/produits\/freeze-begbugs\/\">FREEZE<\/a> aerosol.<\/p>\n\n\n\n<p><strong>\u27a1\ufe0f To find out more: <\/strong><a href=\"https:\/\/www.sereni-d.com\/en\/our-advice\/bed-bugs-a-step-by-step-protocol-for-action\/\" target=\"_blank\" rel=\"noreferrer noopener\">The complete bed bugs protocol<\/a>.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large has-custom-border\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit-1024x684.jpg\" alt=\"\" class=\"wp-image-3751\" style=\"border-radius:10px\" srcset=\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit-1024x684.jpg 1024w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit-300x200.jpg 300w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit-768x513.jpg 768w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit-600x401.jpg 600w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Inspecter-le-matelas-pour-detecter-les-punaises-de-lit.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Traces of blood on bedding<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage-1024x683.jpg\" alt=\"\" class=\"wp-image-3732\" srcset=\"https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage-1024x683.jpg 1024w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage-300x200.jpg 300w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage-768x512.jpg 768w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage-600x400.jpg 600w, https:\/\/www.sereni-d.com\/wp-content\/uploads\/2023\/11\/Comment-detecter-la-presence-de-punaise-de-lit-en-voyage.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div class=\"wp-block-columns has-border-color has-background is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\" style=\"border-color:#00927b;border-style:solid;border-width:2px;border-radius:20px;background-color:#00927b\">\n<div class=\"wp-block-column has-white-color has-text-color has-link-color wp-elements-18e7052fd80576becaeedbc4f88ba11e is-layout-flow wp-container-core-column-is-layout-5dafc681 wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-center has-white-color has-text-color has-link-color wp-elements-d66871adeff2d577d0d279c8612ae932\">Bed bugs often leave traces of blood on sheets, covers and bedding. These bloodstains are <strong>small, bright red or dark brown<\/strong>, and located around the areas where you sleep.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p>At night, if you move around while you&#8217;re asleep, it&#8217;s common to crush bedbugs that are full of blood after their meal.<\/p>\n\n\n\n<p>What&#8217;s more, a bedbug can absorb up to twice its own weight. When it has eaten too much, it can leave a trail of blood behind.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How do you clean bloodstains from bedding?<\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Act quickly<\/strong>: As soon as you spot a stain, treat it immediately before it dries, as fresh stains are easier to remove.<\/li>\n\n\n\n<li><strong>Use cold water<\/strong>: Soak the affected area in cold water. Avoid hot water, which can set the stain.<\/li>\n\n\n\n<li><strong>Apply bicarbonate of soda<\/strong>: Prepare a paste with bicarbonate of soda and a little water, apply it to the stain and leave for 30 minutes before rinsing.<\/li>\n\n\n\n<li><strong>Mild soap or stain remover<\/strong>: Apply a mild soap or stain remover specifically for blood stains (such as percarbonate-based products). Scrub gently with a soft bristle brush.<\/li>\n\n\n\n<li><strong>Wash at high temperature<\/strong>: Put stained clothes in the washing machine at 60\u00b0C to remove all traces of stain and reduce the risk of parasites spreading.<\/li>\n\n\n\n<li><strong>Natural option<\/strong>: You can also use white vinegar or lemon juice.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">Use a bed bugs with mattress cover<\/h4>\n\n\n\n<p>You can protect your bedding with a special bed bugs with mattress cover. Similar to an anti-dust mite cover, it&#8217;s made from a multi-layered non-woven fabric. It forms a total barrier against bed bugs trapped inside.
