Rat traps Toronto. Do it yourself rat control and removal products. Wide selection of effective rat traps. Lethal and humane options available. While not as effective and efficient as a professional rat treatment, trapping and removing can produce results if several traps are set and monitored regularly. Since the gestation period for rats is under a month, any trapping program should aim at a quick reduction of the population. These traps should be used indoors to avoid any killing of non-target species like squirrels and chipmunks. The Exterminators Inc. also offers professional rat control Toronto services performed by licensed exterminators across the GTA.
