I found that learning about rat behavior and habits particularly helpful as I tried to understand, outsmart, outgun and defeat the critters living under our chicken coop.
Rats have poor eyesight (and they’re nocturnal, evolution is a joker) relying more on their hearing and their excellent senses of smell, taste and touch. They are considered color-blind. Therefore, for safety reasons, baits can be dyed distinctive colors without causing avoidance by rats. The baits we bought are green, I’d make them blaze (hunter) orange.
Rats use their keen sense of smell to locate food items and to recognize other rats. Their sense of taste is excellent, and they can detect some contaminants in their food at levels as low as 0.5 parts per million. That’s freaky good, kinda like a supertaster.
Norway rats usually construct nests in below-ground burrows or at ground level. In our case, the burrow was under the storage area of our coop.

Females may come into heat every four or five days, and they may mate within a day or two after a litter is born. Breeding often peaks in spring and fall, with reproductive activity declining during the heat of summer and often stopping completely in winter, depending on habitat. These seasonal trends are most pronounced in more severe climates. The average female rat has four to six litters per year and may successfully wean 20 or more offspring annually.
Studies indicate that during daily activities, a rat normally travels an area averaging 100 to 150 feet in diameter. Rats seldom travel farther than 300 feet from their burrows to obtain food or water. Rats constantly explore and learn about their environment, memorizing the locations of pathways, obstacles, food and water, shelter, and other elements in their domain. They quickly detect and tend to avoid new objects placed into a familiar environment. Thus, objects such as traps and bait stations often are avoided for several days or more following their initial placement.
Knowing all of this can be helpful when planning a rat removal or extermination program.
