This is challenging because people typically move around during daylight hours. To reach a host and feed, a bed bug needs the host to stay completely still for long enough, such as on transport like trains, buses and aeroplanes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How long can bed bugs survive without feeding?<\/strong><\/h3>\n\n\n\n<p>Female bed bugs need regular blood meals to produce their eggs \u2014 typically one batch of <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3255965\/\">5 to 8 eggs per week over 18 weeks<\/a> \u2014 but they can survive for long periods without a meal.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Adults can survive for <strong>several months<\/strong> without a host under standard indoor conditions.<\/li>\n\n\n\n<li>They can survive for <strong>over a year <\/strong>without feeding, in cooler temperatures, when their metabolism slows significantly.<\/li>\n<\/ul>\n\n\n\n<p>This survivability is particularly significant for vacant rooms or properties, or trade in second-hand furniture, when infestations can reactivate immediately upon the introduction of a new host.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.rentokil.co.uk\/blog\/wp-content\/uploads\/2026\/07\/bedbugs-inspection.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"814\" height=\"429\" src=\"https:\/\/www.rentokil.co.uk\/blog\/wp-content\/uploads\/2026\/07\/bedbugs-inspection.jpg\" alt=\"Man Inspecting a  Mattress For Bedbug Infestation With a Magnifying Glass.\" class=\"wp-image-23218\" srcset=\"https:\/\/www.rentokil.co.uk\/blog\/wp-content\/uploads\/2026\/07\/bedbugs-inspection.jpg 814w, https:\/\/www.rentokil.co.uk\/blog\/wp-content\/uploads\/2026\/07\/bedbugs-inspection-300x158.jpg 300w, https:\/\/www.rentokil.co.uk\/blog\/wp-content\/uploads\/2026\/07\/bedbugs-inspection-768x405.jpg 768w\" sizes=\"auto, (max-width: 814px) 100vw, 814px\" \/><\/a><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"five-health-impacts\"><strong>Five health impacts from bed bug bites and infestations<\/strong><\/h2>\n\n\n\n<p>Bed bug infestations affect human health through both direct physiological reactions to bites and indirect psychological stress. While they are not primary disease vectors, their presence can cause severe skin irritation, secondary bacterial infections, profound sleep deprivation, clinical anxiety, and, in severe cases, chronic conditions like anaemia or respiratory distress.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Skin irritation<\/strong><\/h3>\n\n\n\n<p>When a bed bug feeds, it pierces the skin with needle-like mouthparts and injects saliva containing at least <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3255965\/\">46 unique proteins<\/a>. These proteins facilitate feeding by acting as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Anticoagulants:<\/strong> Keep blood flowing smoothly.<\/li>\n\n\n\n<li><strong>Vasodilator inducers:<\/strong> Widen blood vessels near the bite.<\/li>\n\n\n\n<li><strong>Platelet aggregation inhibitors:<\/strong> Preventing blood from clotting during feeding.<\/li>\n\n\n\n<li><strong>Anaesthetics and antimicrobials:<\/strong> Help the bug go unnoticed while feeding and reduce local infection.<\/li>\n<\/ul>\n\n\n\n<p>Your body\u2019s immune system identifies these proteins as foreign, causing it to release histamine and trigger localised inflammation. Symptoms vary widely by person: bites may appear as small red spots, develop into large, itchy welts or, in rare cases, form fluid-filled blisters.<\/p>\n\n\n\n<p>Symptoms can appear within minutes or take up to 10 days to develop, and they may take weeks to fully resolve. Importantly, repeated exposure to bed bugs often leads to increasingly severe reactions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Secondary skin infections from bites<\/strong><\/h3>\n\n\n\n<p>The intense pruritus (itching) associated with bed bug bites frequently compels the victim to scratch the affected areas. Aggressive scratching breaks the skin barrier, creating an open gateway for opportunistic bacteria. This mechanical damage can lead to <a href=\"https:\/\/pedsderm.net\/site\/assets\/files\/1028\/spd_skin_infections_color_web_1.pdf\">secondary bacterial infections<\/a>, such as impetigo, cellulitis, ecthyma and folliculitis. It is also possible that scratching can introduce microorganisms from bed bug faeces into wounds in the skin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. The psychological toll of sleep disturbance and anxiety<\/strong><\/h3>\n\n\n\n<p>The mental health issues caused by an active infestation are frequently as debilitating as the physical bites. The presence of bed bugs can significantly disrupt normal sleep, due to the physical discomfort of itchy bites and the pervasive worry of having live insects actively feeding in your bed. Documented long-term effects include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Elevated anxiety and persistent daytime tiredness.<\/li>\n\n\n\n<li>Heightened risks of clinical depression.<\/li>\n\n\n\n<li>Measurable cognitive impairment.<\/li>\n\n\n\n<li>Broader chronic conditions, including an increased risk for coronary heart disease.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Anaemia from long-term blood feeding<\/strong><\/h3>\n\n\n\n<p>In severe, long-term infestations where bed bug populations remain unchecked, the cumulative impact of multiple and frequent bites can induce anaemia, especially in children.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Historical context: <\/strong>The reality of this physiological drain was famously demonstrated in a <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3255965\/\">seminal scientific work on bed bugs<\/a>. The researcher maintained a private bed bug colony by allowing them to feed exclusively on his own body, successfully tracking a measurable, multi-year decline in his personal haemoglobin levels.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Respiratory complications<\/strong><\/h3>\n\n\n\n<p>Bed bug infestations introduce significant amounts of respiratory irritants into indoor air. As populations grow, biological debris accumulates and becomes airborne, acting as potent allergens. Key contributors include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Exuviae: <\/strong>Shed skins from moulting cycles.<\/li>\n\n\n\n<li><strong>Waste matter: <\/strong>Microscopic faecal particles and dried blood spots.<\/li>\n\n\n\n<li><strong>Reproductive detritus: <\/strong>Empty egg cases and related biological remains.<\/li>\n<\/ul>\n\n\n\n<p>The presence of bed bugs in homes has been linked to <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9060000\/\">patients attending emergency departments<\/a> with respiratory complaints, and those with asthma or COPD having more emergency department visits.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Summary of the health impacts of a bed bug infestation.<\/strong><\/h3>\n\n\n\n<div class=\"bedbug-custom-table-wrapper\" style=\"margin: 20px 0 !important;

Effective control requires more than standard DIY treatments; it demands an expert-led Integrated Pest Management (IPM) approach to thoroughly target infestations and prevent their spread. If you suspect an infestation, professional intervention is the most reliable way to ensure all clusters are eliminated.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-vivid-red-background-color has-background has-text-align-center wp-element-button\" href=\"https:\/\/www.rentokil.co.uk\/bed-bugs\/\"><strong>Contact our experts today for professional, effective bed bug removal.<\/strong><\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQs<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Do bed bugs transmit diseases to humans?<\/strong><\/h3>\n\n\n\n<p>No, bed bugs are not known to transmit diseases to humans. While they are capable of carrying human pathogens in their bodies, there is no evidence that they can spread them to people through their bites.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. What are the primary health risks of a bed bug infestation?<\/strong><\/h3>\n\n\n\n<p>The main health impacts include skin irritation (itching, swelling, redness) and potential secondary bacterial infections caused by scratching. Other impacts include sleep disruption, anxiety, and, in severe cases of long-term infestation, anaemia.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Why do bed bug bites cause such intense itching?<\/strong><\/h3>\n\n\n\n<p>When bed bugs feed, they inject saliva containing various proteins \u2014 including anticoagulants and anaesthetics \u2014 into the skin. The body&#8217;s immune system identifies these proteins as foreign, triggering an inflammatory response that causes itching and swelling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. How can I tell if I have been bitten by bed bugs?<\/strong><\/h3>\n\n\n\n<p>Symptoms vary from person to person. Bites often appear as small red spots, which may develop into large, itchy welts. In rare cases, they can form fluid-filled blisters. Reactions can take anywhere from a few minutes to 10 days to appear.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Can a bed bug infestation affect mental health?<\/strong><\/h3>\n\n\n\n<p>Yes. The stress of knowing live insects are in your sleeping area, combined with physical discomfort and sleep deprivation, can lead to chronic insomnia, persistent anxiety, and, in some cases, symptoms of clinical depression.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Are you worried about the health impacts of bed bug bites?
