Behaviour: they are generally smaller in size compared to rats. Mice are excellent climbers and are capable of gaining entry through holes around vents and around cables entering the building. They contaminate food items and their presence alone is enough to call for a rodent control treatment. They feed unto anything and produce rapidly.
Trapping is the safest and most effective method for controlling rats in and around homes, garages, and other structures. Because snap traps can be used over and over, trapping is less costly than poison baits but more labor intensive. Traps can be set and left indefinitely in areas such as attics where rats have been a problem in the past. The simple, wooden rat-
Glue traps, which work on the same principle as flypaper, aren’t recommended for controlling rats, as they are much less effective for rats than for mice. A major drawback with glue boards and other live-
Rodenticides (Toxic Baits)
While trapping is generally recommended for controlling rats indoors, when the number of rats around a building is high, you might need to use toxic baits to achieve adequate control, especially if there is a continuous reinfestation from surrounding areas. If this is the case, consider hiring a licensed pest control applicator who is trained to use rodenticides safely.
Baits to control rodents are formulated with an attractant (generally food) and a rodenticide (toxin). Changes in rodenticide regulations went into effect in mid-
