Stress for the animals, drop in production, deterioration in egg quality&#8230; The consequences are both <strong>sanitary <\/strong>and <strong>economic<\/strong>.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">When faced with a build-up of pressure, the key is not just <strong>to act quickly<\/strong>, but <strong>to act methodically.<\/strong> Here are the essential steps for effectively managing an infestation, from detection to lasting stabilization.<\/p>\n<\/div><\/div>\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"row\"><div class=\"col-12 heading\">\n<h3 class=\"wp-block-heading\">Start by measuring: an essential step for taking the right action<\/h3>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">When an infestation is suspected, the first mistake would be to intervene <strong>without a precise assessment.<\/strong> However, the success of the strategy depends above all on a good knowledge of the level of pest pressure.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">Setting up red mites traps in the building is <strong>an essential starting point. <\/strong>Positioned in refuge areas (perches, nests, structures), they provide an objective view of the situation. Monitoring should be carried out on a <strong>regular basis <\/strong>&#8211; ideally every month &#8211; to identify trends and not just crisis situations.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">The results obtained can then be used to <strong>classify the infestation<\/strong> according to different levels, from weak to critical. This reading is essential, as it determines the type of response required. A moderate infestation cannot be managed in the same way as an acute episode.  <\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">With this in mind, the use of a tracking tool like Acaritool enhances <strong>decision-making.<\/strong> By centralizing counting data, it becomes possible to :<\/p>\n<\/div><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Monitoring population trends over time<\/li>\n\n\n\n<li>Clearly visualize acceleration phases<\/li>\n\n\n\n<li>Identify the periods most at risk<\/li>\n<\/ul>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">This approach enables us to move from &#8220;intuitive&#8221; management <strong>to data-driven management.<\/strong> In other words, we no longer suffer infestations: we anticipate them.<\/p>\n<\/div><\/div>\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"row\"><div class=\"col-12 heading\">\n<h3 class=\"wp-block-heading\">React quickly to break the infestation dynamic<\/h3>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">When indicators show high pressure, the challenge is to rapidly reduce the mites population to <strong>limit the impact on the animals.<\/strong><\/p>\n<\/div><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Decline in egg-laying<\/li>\n\n\n\n<li>Stress behaviors (nocturnal agitation, discomfort)<\/li>\n\n\n\n<li>Mortality risks in the most severe cases<\/li>\n<\/ul>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">However, this step must be strictly reasoned. Repeated or poorly controlled use of chemical solutions can have a number of undesirable effects: the development of resistance, higher costs, and increased regulatory constraints. <\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">That&#8217;s why this curative action phase must always be part of a broader strategy.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">Once the pressure has been reduced, it is essential to follow up with an in-depth approach designed to prevent relapses. The Acari\u00aeprogram is part of this ongoing management approach.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">This program is based on the combination of two complementary types of action:<\/p>\n<\/div><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Internal action with <a href=\"https:\/\/www.deltavit.com\/en\/product\/acariflash\/\" data-type=\"link\" data-id=\"https:\/\/www.deltavit.com\/produit\/acariflash\/\">Acariflash\u00ae<\/a>, distributed via drinking water or feed, for a <strong>continuous repellent and regulating effect<\/strong><\/li>\n\n\n\n<li>External action with <a href=\"https:\/\/www.deltavit.com\/en\/product\/acaritec\/\" data-type=\"link\" data-id=\"https:\/\/www.deltavit.com\/produit\/acaritec\/\">Acaritec\u00ae<\/a>, applied directly to the environment (sprinkling, dry spraying or spray), to <strong>create a physical barrier<\/strong> limiting the proliferation of lice<\/li>\n<\/ul>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">The advantage of this combination is that it acts on both the animal and its environment, enabling better control of the parasite&#8217;s cycle.<\/p>\n<\/div><\/div>\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"row\"><div class=\"col-12 heading\">\n<h3 class=\"wp-block-heading\">Setting up a sustainable strategy to avoid new crises<\/h3>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">First and foremost, we need to be <strong>able to adjust our practices<\/strong> according to the actual situation. Dosages and protocols must evolve in line with : <\/p>\n<\/div><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>the level of infestation observed<\/li>\n\n\n\n<li>trapping results<\/li>\n\n\n\n<li>high-risk periods, such as hot weather or certain phases of the production cycle<\/li>\n<\/ul>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">This ongoing adaptation enables us to move <strong>from a curative approach to a dynamic, preventive management approach.<\/strong><\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">Moreover, effectiveness depends on a combination of approaches. The combination of <strong>one-off<\/strong> <strong>chemical treatments<\/strong> <strong>and continuous natural solutions<\/strong> enables us to maintain a low level of infestation while limiting the need for heavy treatments. This strategy also helps to <strong>slow down the emergence of resistance<\/strong> and keep pace with regulatory changes.  <\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">At the same time, observation of the animals remains a valuable indicator. Any <strong>deterioration in <\/strong>behavior (stress, agitation), performance (drop in egg-laying rate) or general condition should be interpreted as a warning signal. In such situations, it is essential to quickly readjust the protocol.  <\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">Finally, the implementation of an <strong>annual management plan<\/strong> is a decisive lever. By anticipating periods favorable to red mites, <strong>planning interventions and structuring monitoring<\/strong>, seasonal infestations can be controlled rather than suffered.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">In the face of red mites, effectiveness is based on a structured approach in <strong>three key stages:<\/strong><\/p>\n<\/div><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Measure precisely to adapt response<\/li>\n\n\n\n<li>Act quickly in the event of heavy pressure<\/li>\n\n\n\n<li>Maintaining a sustainable balance through an ongoing strategy<\/li>\n<\/ul>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">The ultimate goal is not to totally eliminate the parasite &#8211; an often illusory objective &#8211; but to <strong>stabilize its level at a controlled threshold,<\/strong> compatible with the performance of the farm and the well-being of the animals.<\/p>\n<\/div><\/div>\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\">Rigorous management thus makes it possible to reconcile <strong>technical efficiency, cost control and sustainable practices.<\/strong><\/p>\n<\/div><\/div>\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><\/figure>\n\n\n\n<figure class=\"wp-block-gallery alignwide has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"684\" data-id=\"5141\" src=\"https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-1024x684.jpeg\" alt=\"\" class=\"wp-image-5141\" srcset=\"https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-1024x684.jpeg 1024w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-300x200.jpeg 300w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-768x513.jpeg 768w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-1536x1026.jpeg 1536w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-1900x1269.jpeg 1900w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-1320x881.jpeg 1320w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-990x661.jpeg 990w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-660x441.jpeg 660w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-450x300.jpeg 450w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-330x220.jpeg 330w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-180x120.jpeg 180w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1-500x334.jpeg 500w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_90186836-1.jpeg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"5123\" src=\"https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-1024x683.jpeg\" alt=\"\" class=\"wp-image-5123\" srcset=\"https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-1024x683.jpeg 1024w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-300x200.jpeg 300w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-768x512.jpeg 768w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-1536x1024.jpeg 1536w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-1900x1267.jpeg 1900w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-1320x880.jpeg 1320w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-990x660.jpeg 990w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-660x440.jpeg 660w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-450x300.jpeg 450w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-330x220.jpeg 330w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-180x120.jpeg 180w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347-500x333.jpeg 500w, https:\/\/www.deltavit.com\/wp-content\/uploads\/AdobeStock_349969347.jpeg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n\n\n<div style=\"height:88px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"row\"><div class=\"col-12 paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>In laying hen farming, episodes of red mites infestation can quickly become critical.
