My nemesis are these little long-tailed furry rodents with the overbite. Yeah, they're cute and all, but very destructive to my humble abode. I've resolved they must be terminated. FYI not fond of poisoning option; have seen the suffering it engenders. They have eaten an entrance hole on the second level and an egress area on the opposite side of the house, same level. I patched it up; they chewed clean through my work short order. Last several weeks I hired some contractors to install discrete concrete wall-barriers on their front and back doors. They simply chose a nearby site. Nocturnally I hear them squeaking or chattering-- likely about my futlity in ridding them, I suspect. They mock me! Time to break out my arsenal? Hire exterminators? Your expert (Pro) opinions or those homeowners who have successfully defeated these little devils greatly appreciated. Tanks.
