Caulking as a pest control solution in the home
In the perpetual fight against infestations, caulking is a great ally, especially when it comes to preventing the intrusion of mice. A question of hygiene for some and a source of phobias for others, parasites, whether they take the form of insects, rodents or other small unwanted animals, are unanimously undesirable in our living spaces. Their intrusion into our homes causes damage to our homes and pantries, with potential consequences for our health.
It is preferable to adopt a preventive rather than a curative approach, a principle that makes sense in the context of infestations. This phenomenon is gaining ground in Quebec and requires adequate measures to counter it. With this in mind, caulking, especially to prevent mouse access, is emerging as a promising strategy to protect our living spaces and ensure our well-being.
Caulking your home is one of the most effective ways to prevent these nuisances from sneaking inside through small holes, cracks and gaps.
