Rats
The average Norway rat is about 16 inches long and weighs about 340 grams. A single female can produce over 60 offspring in a year.
Field signs
Droppings, gnaw marks on wood and wiring, burrows near foundations, noises in walls after dark.
Norway rats reach sexual maturity in 75 to 90 days and average 6 to 14 pups per litter, with 3 to 6 litters in a typical year. In ideal conditions, inside a structure with no predators or weather to fight, that can climb to 10 or 12 litters.
Rats squeeze through openings as small as half an inch. Common entry points are under garage doors, gaps where the soffit meets the brick, central vac lines and air conditioner hose penetrations.
The treatment
Licensed anticoagulant formulations in palatable meal bait deliver long term control without the odour problems of over the counter products, which rodents build immunity to over time.
