Indeed, since sewers are places where rats like to settle, it is not uncommon to see them pass through a crack in the pipe to sneak into your home or business. <\/p>\n\n<h2 class=\"wp-block-heading\">Detect rodent entries using a rat smoke test<\/h2>\n\n<p class=\"wp-block-paragraph\">To determine if rats or mice enter your home (or business) through the pipes of your sewer system (cracks, holes, breaks in joints, connections or pipes), a rat smoke test is a quick and very effective solution.<\/p>\n\n<p class=\"wp-block-paragraph\">Nova Extermination technicians will inject a smoke under pressure into the drainage systems and sewer pipes, in order to find the failure. It is then possible to find out if a broken piece of pipe or a crack is allowing rats to infiltrate. This process (rat smoke test) also makes it possible to detect water leaks and gas infiltration.  <\/p>\n\n<p class=\"wp-block-paragraph\">Smoke is not dangerous or toxic to humans, animals or plants. It does not leave residues or stains. The smoke has a particular smell to make it easier to detect, but this smell only lasts a few minutes.  <\/p>\n\n<h2 class=\"wp-block-heading\">Where our fumigation diagnostics are most in demand<\/h2>\n\n<p class=\"wp-block-paragraph\">The smoke test reveals the airtightness defects in the envelope, and our request focuses on older buildings. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-in-longueuil\/\">Longueuil and Saint-Hubert<\/a>, the brick triplexes in Old Longueuil produce the most positive tests at the soffits and roof-wall junctions. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-brossard\/\">Brossard and the southern South Shore<\/a>, the test mainly targets the junctions of houses in sectors A to D, which are older. The <a href=\"https:\/\/www.novaextermination.com\/en\/exterminateur-rive-sud-3\/\">South Shore smoke test<\/a> is a popular service before the real estate purchase to validate the envelope. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-boucherville\/\">Boucherville and the surrounding area<\/a>, Old Boucherville regularly requests service on its eighteenth-century heritage houses. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-jean-sur-richelieu\/\">Saint-Jean-sur-Richelieu (Richelieu Valley),<\/a> the stone buildings of the fort and the historic district often provide a revealing diagnosis. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-hyacinthe\/\">Saint-Hyacinthe and the Maskoutains<\/a>, the heritage downtown around the cathedral is the focus of requests.      <\/p>\n\n<h2 class=\"wp-block-heading\">Did you know?<\/h2>\n\n<p class=\"wp-block-paragraph\">Rats are extremely intelligent and can dig tunnels for many miles without getting lost!<\/p>\n\n<li>We plug the plumbing vent on the roof.<\/li>\n\n<li>We fill all drains with water.<\/li>\n\n<li>We propel the smoke into the plumbing pipes under pressure for about 15 minutes.<\/li>\n\n<li>We inspect to determine if smoke is coming out through holes or cracks.<\/li>\n\n<li>We unclog the roof vent to let the smoke escape.<\/li>\n\n<h2 class=\"wp-block-heading\">KEEP THEM FROM COMING BACK!<\/h2>\n\n<p class=\"wp-block-paragraph\">After identifying the cracks through which rats sneak into your home, we make sure that they are well sealed so that they don&#8217;t come back anytime soon. Our caulking solutions are particularly effective in solving your rat infestation problem permanently. <\/p>\n\n<h2 class=\"wp-block-heading\">A SIMPLE AND EFFECTIVE SOLUTION<\/h2>\n\n<p class=\"wp-block-paragraph\">The rat smoke test is the first step in an extermination to solve your rat problem permanently. Among other things, the rat smoke test:<br\/>Detects even the smallest cracks<br\/>Does not require unnecessary and expensive work<br\/>Offers reliable and accurate diagnosis<br\/>The rat smoke test is a simple and ingenious process that is very effective in identifying the main cause of the presence of rats in your home or business. <\/p>\n\n<h2 class=\"wp-block-heading\">RAPID EXTERMINATION OF RATS ON THE SOUTH SHORE<\/h2>\n\n<p class=\"wp-block-paragraph\">Our extermination company on the South Shore will be able to perform a rat smoke test as well as the capture of rats that have infiltrated your home or business, at a very affordable price.
