During a deratization intervention, the first thing to do is to assess the sources of rodents infiltration.
Sewer rats go up into the sanitary plumbing systems of buildings in search of food, quiet space away from predators, to settle and give birth to their young.
Unfortunately, nothing can prevent rats from circulating in the sanitary and rain ducts of a building.
The most important thing is that your systems are 100% waterproof between the city sewer and the plumbing vent on the roof of your home. In the event that a problem is present, a pipe failure, an unfloored floor drain, a vent left open in a closed wall, a deterioration of old period materials or any other system defect, a smoke test or camera test investigation becomes essential to detect the problem.
Thereafter a report of the work needed to correct the problems will be provided with a cost assessment to solve your problem in a complete and definitive way. Through processes we advise to proceed with the extermination of rats with conventional rat traps that allow us to collect the carcasses of rodents, rather than using a poison rodenticide that would kill the rats in your house causing ultra unpleasant smells of decomposition which can last several weeks. Subsequently we suggest assessing the degree of contamination of the property caused by feces and urine left by rats. HEALTH CANADA studies show that rat feces and urine are highly harmful to humans. Our experts will help you and advise you throughout the relevant steps to correct the problem.
