  The common wooden snap traps that are effective for Norway rats are effective for roof rats. The damage control methods used for roof rats are essentially the same as for Norway rats. They can transmit these diseases through physical contact, bites, by contamination or by fleas that are feeding on the rodent. Traditional baiting or trapping on the ground or floor may intercept very few roof rats unless bait and/or traps are placed at the very points that rats traverse from above to a food resource. While they may not kill the stalk outright, secondary organisms generally invade and reduce the sugar quality. They have coarse, brown fur, with lighter fur on the undersides. Usually the peaks in breeding occur in the spring and fall. Other rat signs may also assist, but be aware that both species may be present.
  This is a great supplementary treatment to trapping when you are dealing with larger rodent populations, or for outdoor populations. Most information on this subject comes from populations confined in cages or outdoor pens. It has often been said that Norway rats will displace roof rats whenever they come together, but the evidence is not altogether convincing. Lights (flashing or continuously on) may repel rats at first, but rats will quickly acclimate to them. Proper ladder safety is a must, as is roof safety. A rat does not want to be exposed to danger outside for very long! If you think you can just seal shut the entry holes into the house during the daylight when they are outside, that is incorrect. The great adaptability of rats to human-created environments and the high fertility rate of rats make for quick recuperation of their populations. Rats rely more on their keen senses of smell, taste, touch, and hearing than on vision. Their burrowing habitats include soil along building foundations, under woodpiles and other piles of debris. Sounds Noises produced by scurrying rats, scratching in the walls or other noises from nest building may tip off the property owner to a rat problem. Some of the first-generation anticoagulants (pindone and warfarin) are available as soluble rodenticides from which water baits can be prepared.
  Trapping Other rodenticides. Inspection is an important first step in getting rid of rats. They also feed on a variety of vegetative parts of ornamental and native plant materials. A few baits are strong enough to cause death with a single feeding. Hundreds may be nesting in a city block-in underground burrows, in sewers, on roofs, inside buildings-with few people in the area realizing it. Female adults will produce about seven litters per year and will mate again about 18 hours after giving birth to her litter of about eight pups. Roof rats have hairless, scaly tails that are longer than their heads and bodies. The preferred habitat of Norway rats is just about anywhere people reside. Other vegetable, melon, berry, and fruit crops occasionally suffer relatively minor damage when adjacent to infested habitat such as riparian vegetation. Hantavirus pulmonary syndrome is transferred via inhalation of rodent urine, droppings or saliva.
