When temperatures warm up in spring or on sunny winter days, they become active and try to exit the walls to reach the home&#8217;s living spaces.<\/p>\n<p>This phenomenon can sometimes give the impression that an infestation appears suddenly when the insects have actually been present for several months.<\/p>\n<h3 style=\"margin-top: 40px !important; font-weight: bold !important;\">How can you identify a house fly?<\/h3>\n<p>The house fly is probably one of the most recognizable fly species.<\/p>\n<p>Key identifying characteristics include:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Size generally ranging from 6 to 8 mm;<\/li>\n<li>Gray to brown body;<\/li>\n<li>Thorax marked with dark stripes;<\/li>\n<li>Red or reddish-brown eyes;<\/li>\n<li>Fast and agile flight.<\/li>\n<\/ul>\n<p>House flies are commonly found:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Near windows;<\/li>\n<li>Around light fixtures;<\/li>\n<li>In kitchens;<\/li>\n<li>In garages;<\/li>\n<li>In attics;<\/li>\n<li>Near sources of light.<\/li>\n<\/ul>\n<p>When they emerge from wall voids in the spring, they often gather around windows as they attempt to make their way outdoors.<\/p>\n<h3 style=\"margin-top: 40px !important; font-weight: bold !important;\">Why do house flies enter your home?<\/h3>\n<p>In fall, house flies seek sheltered locations to survive the winter.<\/p>\n<p>They can enter a residence through:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Cracks in exterior cladding;<\/li>\n<li>Window frames;<\/li>\n<li>Soffits;<\/li>\n<li>Vents;<\/li>\n<li>Openings around conduits;<\/li>\n<li>Poorly sealed gaps.<\/li>\n<\/ul>\n<p>Sun-exposed walls are particularly attractive as they provide additional warmth.<\/p>\n<p>Once settled in wall cavities or attics, they generally remain inactive until more favourable temperatures return.<\/p>\n<h3 style=\"margin-top: 40px !important; font-weight: bold !important;\">Are house flies dangerous?<\/h3>\n<p>House flies do not cause damage to the structure of a building.<\/p>\n<p>However, they can pose a health concern when they come into contact with food and food preparation surfaces.<\/p>\n<p>They may:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Contaminate food products;<\/li>\n<li>Soil surfaces;<\/li>\n<li>Carry various microorganisms;<\/li>\n<li>Become a significant nuisance when present in large numbers.<\/li>\n<\/ul>\n<p>In some cases, the accumulation of dead flies in walls, ceilings, or attics can also attract other opportunistic insects, including:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Larder beetles;<\/li>\n<li>Certain beetle species;<\/li>\n<li>Other insects that feed on decaying organic matter.<\/li>\n<\/ul>\n<h3 style=\"margin-top: 40px !important; font-weight: bold !important;\">Why does the problem keep coming back every year?<\/h3>\n<p>House flies often use the same entry points year after year.<\/p>\n<p>When a home provides suitable overwintering conditions, new flies may return each fall.<\/p>\n<p>The most common contributing factors include:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Cracks or openings in the building;<\/li>\n<li>Deteriorated caulking or weatherproofing;<\/li>\n<li>Damaged soffits or vents;<\/li>\n<li>Wall voids suitable for overwintering;<\/li>\n<li>Sun-exposed facades.<\/li>\n<\/ul>\n<p>Without corrective measures, the problem may continue to reoccur year after year.<\/p>\n<h3 style=\"margin-top: 40px !important; font-weight: bold !important;\">What should you do if you have house flies in your home?<\/h3>\n<p>When large numbers of flies appear in the spring, they can often be removed using a vacuum cleaner or appropriate traps.<\/p>\n<p>However, this approach does not address the root cause of the problem.<\/p>\n<p>To reduce their presence over the long term, it is important to:<\/p>\n<ul style=\"margin-bottom: 20px !important;\">\n<li>Identify entry points;<\/li>\n<li>Seal accessible openings;<\/li>\n<li>Improve the building&#8217;s weatherproofing;<\/li>\n<li>Determine which areas are being used for overwintering.<\/li>\n<\/ul>\n<p>Because every building is different, the most effective strategy often depends on its design and overall condition.<\/p>\n<h3 style=\"margin-top: 40px !important;
