It is very important to act quickly to eliminate them. These insects reproduce very quickly and can form multiple nests in your floors, walls, attic, etc. Nova Extermination&#8217;s specialized technicians will be able to solve your problem quickly and durably (by caulking the possible entrances). We offer this house ant extermination service at an affordable price in all cities on the South Shore of Montreal.    <\/p>\n\n<h2 class=\"wp-block-heading\">General information about ants<\/h2>\n\n<p class=\"wp-block-paragraph\">No matter what species of ants may enter your home, it is important to know what attracts them, and how to remedy their harmful presence inside your home.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is some information that will help you prevent their infestations and how to fix it:<\/p>\n\n<h4 class=\"wp-block-heading\">How to end ants for good<\/h4>\n\n<ul class=\"wp-block-list\">\n<li>Don&#8217;t leave food easily accessible<\/li>\n<li>Avoid direct contact with your home from tree branches, plants, grass, vines, etc.<\/li>\n<li>Caulking your doors and windows<\/li>\n<li>Do not leave rotting wood near your home<\/li>\n<li>Do not leave soiled dishes in the sink<\/li>\n<li>Avoid humidity indoors<\/li>\n<li>Make repairs to decaying materials quickly<\/li>\n<li>Leave firewood outside<\/li>\n<li>Call an exterminator at the first signs to avoid an infestation<\/li>\n<\/ul>\n\n<h4 class=\"wp-block-heading\">Recognizing the ant problem<\/h4>\n\n<ul class=\"wp-block-list\">\n<li>Presence of ants in your home<\/li>\n<li>Observation of ants where food is found<\/li>\n<li>Presence of ants on your exterior foundation<\/li>\n<li>Presence of nests in your paving stone, lawn<\/li>\n<li>Sawdust in your home<\/li>\n<\/ul>\n\n<h4 class=\"wp-block-heading\">Natural Ant Treatments<\/h4>\n\n<ul class=\"wp-block-list\">\n<li>The magic line: Make a chalk line on the path of the ants. As soon as they do so, it will be impossible for them to cross it <\/li>\n<li>Sugar and salt mixture: Although ants love sweet products, salt horrifies them, once they taste it, they won&#8217;t want to go near it!<\/li>\n<li>White vinegar: Spray pure or diluted white vinegar on common areas of ants, the strong smell will repel them!<\/li>\n<li>Homemade products that ants hate: You can spread several types of foods that repel them. Either lemon, lavender, cinnamon, peppermint, basil leaves, cayenne pepper, garlic, or almost any spice that ends up in your kitchen! <\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Did you know?<\/h2>\n\n<p class=\"wp-block-paragraph\">Ants appeared during the Cretaceous period, they lived in the company of dinosaurs! According to a study by Harvard and the Universities of Florida, they date back more than 130 million years, so they survived the Tertiary Era, the area that eradicated the dinosaurs, as well as the Ice Age. <\/p>\n\n<h2 class=\"wp-block-heading\">Methods used for house ant extermination<\/h2>\n\n<p class=\"wp-block-paragraph\">To effectively exterminate house ants, it is necessary to eliminate the workers but also the queen (or queens when there are several nests in the house). Sometimes the queen is in the mother colony outside, while the satellite nests are in your home. For a house ant extermination, bait can be placed on the floors of the house that the ants will bring back to others as well as to the queen. An insecticide can also be applied to at-risk surfaces.   <\/p>\n\n<p class=\"wp-block-paragraph\">We offer this house ant extermination service at an affordable price in all cities on the South Shore of Montreal. We master the techniques to carry out a house ant extermination, and we use insecticides approved by the Ministry of the Environment. <\/p>\n\n<h2 class=\"wp-block-heading\">PLUGGING OF ENTRANCES<\/h2>\n\n<p class=\"wp-block-paragraph\">Unlike other exterminators, we do not just exterminate house ants quickly. If you wish, we will prevent their return by sealing the entry points (cracks and holes around windows, doors, baseboards, etc.). We&#8217;ll walk around your home and inspect all the potentially at-risk areas, then seal them.  <\/p>\n\n<p class=\"wp-block-paragraph\"><img alt=\"\" fetchpriority=\"high\" decoding=\"async\" alt=\"\" class=\"size-medium wp-image-2079 aligncenter\" src=\"https:\/\/www.novaextermination.com\/wp-content\/uploads\/2022\/01\/Nid-fourmis-charpentiere-bois-1-300x225.jpg\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.novaextermination.com\/wp-content\/uploads\/2022\/01\/Nid-fourmis-charpentiere-bois-1-300x225.jpg 300w, https:\/\/www.novaextermination.com\/wp-content\/uploads\/2022\/01\/Nid-fourmis-charpentiere-bois-1.jpg 500w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><br\/>Nova Extermination&#8217;s ant exterminators have a license in good standing from the R\u00e9gie du B\u00e2timent du Qu\u00e9bec (RBQ: 5734-75930-01) as well as from the Commission des normes, de l&#8217;\u00e9quit\u00e9, de la sant\u00e9 et de la s\u00e9curit\u00e9 du travail (CNESST) to carry out the necessary sealing work. We are also protected by comprehensive liability insurance to carry out this work. <\/p>\n\n<h3 class=\"wp-block-heading\">Information about the house ant<\/h3>\n\n<p class=\"wp-block-paragraph\">House ants can be of different types.

We cover all cities on the South Shore of Montreal. <\/p>\n\n<h2 class=\"wp-block-heading\">Daily presence for house ants<\/h2>\n\n<p class=\"wp-block-paragraph\">The fragrant house ant Tapinoma sessile is the most common in Quebec cuisine. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-in-longueuil\/\">Longueuil and the surrounding area<\/a>, our interventions mainly concern condominiums and triplexes in Old Longueuil. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-brossard\/\">Brossard and the southern South Shore<\/a>, kitchens in homes in sectors A to R are the priority areas treated in the spring. Our service on the <a href=\"https:\/\/www.novaextermination.com\/en\/exterminateur-rive-sud-3\/\">South Shore<\/a> applies targeted bait and perimeter barrier treatment. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-boucherville\/\">Boucherville and the surrounding area<\/a>, single-family homes in the Pierre-Boucher sector mobilize our teams in May and June. Further east, in <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-jean-sur-richelieu\/\">Saint-Jean-sur-Richelieu and Haut-Richelieu<\/a>, heritage buildings with old wood floors are the focus of spring invasions. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-hyacinthe\/\">Saint-Hyacinthe and the agri-food sector<\/a>, the kitchens of downtown residences and restaurants account for the bulk of seasonal calls.      <\/p>\n\n<script type=\"application\/ld+json\">{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Service\",\n  \"name\": \"Extermination de fourmis de maison\",\n  \"description\": \"Traitement des fourmis de maison odorantes en cuisine.

It is small (2 to 3 mm), dark brown, and forms trails to sweet food sources in the kitchen. In Boucherville as in Sainte-Julie, it is often noticed near counters and pantries.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Why do house ants enter my home?<\/summary><div class=\"nova-faq__a\"><p>They mainly look for sweet food, humidity and sheltered nesting sites, especially in rainy weather or during hot weather. They like to set up their nests under floors, behind walls, in insulation or near pipes. Once a trail is established to your kitchen, the colony will return to it as long as the source is not cut.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Are house ants dangerous?<\/summary><div class=\"nova-faq__a\"><p>They do not sting or damage wood, but they do contaminate food and surfaces as they travel between garbage and the pantry. The main problem is therefore hygiene and the nuisance of their presence in large numbers. An ignored colony may have several satellite nests, making the infestation persistent.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">What should I prepare before the intervention against house ants?<\/summary><div class=\"nova-faq__a\"><p>We recommend storing food in airtight containers, cleaning up sugary residues, and not crushing or spraying visible tracks before our tour. These leads help our technician locate nests and place bait in the right place. Nova then uses approved products and baiting adapted to the behaviour of this species.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">How much should you plan for a house ant treatment?<\/summary><div class=\"nova-faq__a\"><p>The price is established on the basis of an evaluation, depending on the extent of the situation and the number of households to be treated in your home. There is no single rate, as each home on the South Shore has a different configuration. The amount is clearly communicated to you before the start of the work, all our services being paid.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Will I be rid of house ants for good?<\/summary><div class=\"nova-faq__a\"><p>We aim for sustainable results that are assessed on a case-by-case basis: as this species easily forms satellite nests, a few weeks of monitoring are sometimes necessary. Eliminating colonies with bait and correcting sources of attraction greatly reduces the risk of return. Our technician gives you realistic prevention advice rather than a false promise of absolute elimination.  <\/p><\/div><\/details><\/section><script type=\"application\/ld+json\">{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Comment savoir si j'ai des fourmis de maison plut\u00f4t qu'une autre esp\u00e8ce?\", \"acceptedAnswer\": <span>\"@type\": \"Answer\", \"text\": \"La fourmi de maison, ou fourmi odorante, d\u00e9gage une odeur caract\u00e9ristique de noix de coco ou de pourriture lorsqu'on l'\u00e9crase, ce qui aide \u00e0 l'identifier.
