This movement produces the classic alignment. In clusters, the marks indicate several bugs feeding at the same time on the same area, which happens in more advanced infestations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The size of each mark can vary, sometimes reaching several centimetres depending on the immune reaction. The centre may show a small, darker red dot \u2014 the injection site. Some people develop a larger, almost hive-like reaction with noticeable swelling. Others get tiny blisters filled with clear fluid. It all depends on the individual immune response, which can also change over time: a person who is not very sensitive at first can develop increasingly pronounced reactions after repeated exposure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bed bug bites generally do not burn when they happen. The bed bug injects a local anaesthetic and an anticoagulant before feeding \u2014 you are asleep, you feel nothing. It is in the morning that the itching sets in, sometimes intense, sometimes mild, sometimes absent. Scratching makes things worse: an open sore can become infected. If the marks ooze or are surrounded by spreading redness, see a doctor.<\/p>\n\n\n\n<hr class=\"ep-hr\">\n\n\n\n<h2 class=\"wp-block-heading\">Which areas of the body are targeted, and why does the pattern <span class=\"ep-green\">de piq\u00fbres nocturnes<\/span> follow a precise layout?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Bed bugs target only bare skin exposed during sleep, guided by body heat and exhaled carbon dioxide, which explains why the marks are concentrated on the arms, neck, shoulders, chest and ankles rather than on areas covered by pyjamas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En \u00e9t\u00e9, quand on dort avec peu de v\u00eatements dans un appartement du Mile-End ou de Rosemont, la surface expos\u00e9e est grande \u2014 les piq\u00fbres se distribuent sur de vastes zones. En automne, alors que les nuits fra\u00eechissent et qu&rsquo;on se couvre davantage, les marques se concentrent sur les mains, les avant-bras et le visage, seules parties qui d\u00e9passent des couvertures. Octobre, par exemple, est souvent le mois o\u00f9 les locataires remarquent des piq\u00fbres sur les mains qu&rsquo;ils gardaient auparavant couvertes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bed bugs detect exhaled carbon dioxide from several metres away, but their detection of body heat is limited to a few centimetres. They travel across the floor or the box spring to reach the bed. Once nearby, they look for the most accessible vascular area: neck, wrist, inner ankle, crook of the elbow. They avoid hairy areas such as the scalp \u2014 unlike lice \u2014 and do not venture under clothing worn tight against the skin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding this pattern helps distinguish a bed bug infestation from another cause. If the marks appear under pyjamas, under an elastic waistband or between the toes, look for another culprit. A dermatologist or family doctor can point you in the right direction, but confirmation is always entomological: you have to find the insect or its traces.<\/p>\n\n\n\n<hr class=\"ep-hr\">\n\n\n\n<h2 class=\"wp-block-heading\">How to tell a bed bug bite from a <span class=\"ep-green\">mosquito, flea or mite bite<\/span> ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A bed bug bite differs from a mosquito bite by its grouped pattern and its location limited to areas exposed during sleep; it differs from a flea bite by its larger size and the absence of a marked central entry point; it differs from a reaction to dust mites by the presence of distinct, individual skin lesions rather than diffuse irritation.<\/p>\n\n\n\n<table class=\"ep-table\">\n  <thead>\n    <tr>\n      <th>Features<\/th>\n      <th>Punaise de lit<\/th>\n      <th>Moustique<\/th>\n      <th>Puce<\/th>\n    <\/tr>\n  <\/thead>\n  <tbody>\n    <tr>\n      <td>Pattern<\/td>\n      <td>Line or cluster of 3 to 5 marks<\/td>\n      <td>Isolated, random marks<\/td>\n      <td>Low clusters, often on the feet and ankles<\/td>\n    <\/tr>\n    <tr>\n      <td>Zones typiques<\/td>\n      <td>Neck, arms, shoulders, chest<\/td>\n      <td>All exposed areas, even in the evening<\/td>\n      <td>Feet, ankles, calves, lower back<\/td>\n    <\/tr>\n    <tr>\n      <td>Moment d&rsquo;apparition<\/td>\n      <td>On waking (night only)<\/td>\n      <td>At any time, especially at dusk<\/td>\n      <td>Day and night, contact with an animal or the floor<\/td>\n    <\/tr>\n    <tr>\n      <td>Aspect de la marque<\/td>\n      <td>Red papule, pinkish halo, sometimes a blister<\/td>\n      <td>White then red bump, fades quickly<\/td>\n      <td>Small red mark with a central dot, very itchy<\/td>\n    <\/tr>\n    <tr>\n      <td>Insect sighting<\/td>\n      <td>Hard to see (nocturnal, hides)<\/td>\n      <td>Visible, bourdonne<\/td>\n      <td>Visible on the animal or in the bedding<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">Contrary to a common belief, fleas are not strictly limited to the ankles. They jump and can reach the waist or lower back, especially if a pet sleeps in the bed. What clearly sets them apart is the presence of an infested animal in the home, and the visibility of the insect \u2014 tiny, shiny brown and fast-moving.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mosquitoes, for their part, bite anytime and anywhere, from wrist to calf. Their marks swell and disappear within a few hours. Bed bug bites last several days, even a week, and start again every night as long as the insect has not been eliminated. This nightly recurrence is the strongest indicator.<\/p>\n\n\n\n<hr class=\"ep-hr\">\n\n\n\n<h2 class=\"wp-block-heading\">How long after the bite do <span class=\"ep-green\">bed bug symptoms<\/span> apparaissent-ils ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Symptoms of a bed bug bite appear within a time frame ranging from a few hours to several days depending on individual sensitivity \u2014 a first exposure rarely produces an immediate reaction, while repeated exposures trigger increasingly fast and intense responses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lors d&rsquo;un premier contact, le syst\u00e8me immunitaire n&rsquo;a pas encore d\u00e9velopp\u00e9 de r\u00e9ponse aux antig\u00e8nes de la salive de la punaise. R\u00e9sultat : aucune marque, aucune d\u00e9mangeaison. Cette premi\u00e8re phase silencieuse dure parfois des semaines. C&rsquo;est pourquoi des personnes vivant dans un appartement du Vieux-Rosemont ou de C\u00f4te-des-Neiges peuvent h\u00e9berger une infestation pendant des mois sans le savoir.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After sensitization, the delay gets shorter. The marks appear the next morning, then, after several months of exposure, sometimes in less than an hour. The reaction can progress to hypersensitivity: widespread swelling, hives, and in rare cases a systemic reaction requiring urgent medical attention.<\/p>\n\n\n\n<div class=\"ep-callout\">\n  <strong>\u26a0\ufe0f Warning \u2014 severe allergic reactions:<\/strong> although rare, anaphylactic reactions to bed bug bites have been documented. If you experience shortness of breath, swelling of the face or throat, or widespread hives after repeated nighttime bites, see a doctor or go to the emergency room without delay. People who are immunocompromised or have multiple allergies are at higher risk.\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Conversely, a significant proportion of people simply never develop any visible reaction, no matter how long they are exposed \u2014 estimates vary considerably between studies. These people can contaminate other homes by moving furniture or luggage without ever suspecting they are carrying insects. This is one of the reasons why, according to <a class=\"ep-link\" href=\"https:\/\/donnees.montreal.ca\/dataset\/declarations-exterminations-punaises-de-lit\" target=\"_blank\" rel=\"noopener\">the City of Montreal's open data on bed bug extermination reports<\/a>, les signalements se concentrent dans les secteurs \u00e0 forte mobilit\u00e9 r\u00e9sidentielle, comme le quartier Sainte-Marie.<\/p>\n\n\n\n<hr class=\"ep-hr\">\n\n\n\n<h2 class=\"wp-block-heading\">How to inspect your mattress to confirm the presence of <span class=\"ep-green\">bed bugs in Quebec<\/span> ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To confirm a bed bug infestation, methodically inspect the seams, folds and underside of the mattress for rust-coloured stains (digested blood), black spots (droppings), pale yellow translucent shed skins and pearly one-millimetre eggs \u2014 these four clues together provide reliable entomological evidence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is how to proceed step by step:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n  <li><strong>Remove all sheets and bedding<\/strong>, and slide them into a sealed bag to avoid spreading the bugs.<\/li>\n  <li><strong>Examine the mattress seams<\/strong> with a powerful flashlight \u2014 focus on the edges and corners, favourite spots of <em>Bed bug<\/em>.<\/li>\n  <li><strong>Run a piece of cardboard or a credit card<\/strong> along the seams to flush out hidden bugs and shed skins (translucent exuviae).<\/li>\n  <li><strong>Inspectez le sommier<\/strong>, especially the wooden grooves, staples and areas of folded fabric.<\/li>\n  <li><strong>Check the headboard, frame and bed legs<\/strong> \u2014 screws, bolts and joints are frequent hiding places.<\/li>\n  <li><strong>Examine the baseboards and electrical outlets<\/strong> \u00e0 proximit\u00e9 du lit, surtout dans les logements plus anciens comme ceux du Plateau-Mont-Royal ou de Verdun.<\/li>\n  <li><strong>Notez l&rsquo;odeur<\/strong> : a dense infestation gives off a slightly sweet, rancid smell, sometimes described as coriander or crushed raspberries \u2014 a sign that the colony is established.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If you find clues but no live insects, the infestation may be at an early stage or the bugs may be hiding farther away \u2014 behind picture frames, in the corners of a pantry, under loose flooring. A professional inspection is then needed. Companies holding a pest management business permit (category C5 or D5) issued by the MELCCFP are authorized to carry out this inspection and to use registered pesticides, including the targeted biopesticide Aprehend (based on <em>Beauveria bassiana<\/em>), approved in Canada for bed bug treatment. The company carries out two visits, with the follow-up visit taking place 15 to 20 days after the first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under Quebec's legal framework, any pesticide application in a dwelling must be carried out by a CD5 certificate holder, which can be verified in the <a class=\"ep-link\" href=\"https:\/\/www.quebec.ca\/entreprises-et-travailleurs-autonomes\/permis-certifications\/permis-vente-utilisation-pesticides\" target=\"_blank\" rel=\"noopener\">Quebec government's public register of pesticide permits and certificates<\/a>.

Leur caract\u00e9ristique principale est leur disposition en ligne droite ou en zigzag, souvent par groupes de trois \u00e0 cinq piq\u00fbres align\u00e9es sur la peau. Elles se situent principalement sur les zones expos\u00e9es durant le sommeil : bras, cou, \u00e9paules, jambes et visage. Les piq\u00fbres ne sont pas douloureuses sur le moment car la punaise injecte un anesth\u00e9siant, mais les d\u00e9mangeaisons apparaissent quelques heures apr\u00e8s.

Les piq\u00fbres de moustiques sont isol\u00e9es et apparaissent de fa\u00e7on al\u00e9atoire sur le corps, tandis que les piq\u00fbres de punaises de lit forment des alignements caract\u00e9ristiques appel\u00e9s le \u00ab chemin du petit-d\u00e9jeuner \u00bb. Les piq\u00fbres de punaises de lit provoquent des d\u00e9mangeaisons plus intenses et persistantes, pouvant durer plusieurs jours. De plus, elles surviennent presque exclusivement la nuit et se concentrent sur les zones non couvertes par les draps. L'absence de moustiques dans la pi\u00e8ce combin\u00e9e \u00e0 des piq\u00fbres align\u00e9es oriente fortement vers la punaise de lit.","faq_question_3":"\u00c0 Montr\u00e9al, quelles p\u00e9riodes de l'ann\u00e9e sont les plus \u00e0 risque pour les punaises de lit ?","faq_reponse_3":"Contrairement aux insectes ext\u00e9rieurs, les punaises de lit sont actives toute l'ann\u00e9e \u00e0 Montr\u00e9al car elles vivent exclusivement \u00e0 l'int\u00e9rieur des habitations chauff\u00e9es.

Des petites taches brun-rouge\u00e2tre sur les draps, la literie ou le matelas correspondent aux excr\u00e9ments ou au sang laiss\u00e9s par les insectes. On peut \u00e9galement trouver des mues translucides, car les punaises changent de peau cinq fois durant leur d\u00e9veloppement. Des \u0153ufs blanch\u00e2tres de la taille d'une t\u00eate d'\u00e9pingle se nichent dans les coutures du matelas. Une odeur douce\u00e2tre et musqu\u00e9e caract\u00e9ristique peut aussi \u00eatre perceptible lors d'une infestation avanc\u00e9e.
