Rats are prolific breeders so when you see a rat, you must take immediate action. Rat populations can grow exponentially. Under ideal conditions, a pair of rats could produce 15,000 offspring in the one year.
The following steps provide the basis for effective residential rodent control:
Inspect your property regularly for signs of rodent activity. These signs include:
Rats and mice need to gnaw to keep their constantly growing incisor teeth worn down this will damage woodwork, plastic and lead pipes and sometimes strip insulation from electrical cables.
Holes made by mice tend to be 20mm in diameter, whereas rats tend to be 80mm.
Rodents having established the best route from one place to another use it frequently and this "run" becomes soiled with grease and dirt and leaves a "smear".
Finally, the faeces or droppings of rats and mice are a good indication of the cause, size and duration of the infestation
Manage your grass levels and keep your yard free of rubbish, debris & accumulated building supplies. If you must store materials or equipment outside, do so neatly. Elevate stored items to help reduce nesting. This will also allow you to inspect under and around these items more easily.
Rats will establish a home in your yard if there is an ample food source. To ensure this does not happen do not leave any pet food, dog manure, open garbage cans or cans without tight lids, bags of garbage, bird seed or any other food scraps outside for rats to eat. Never put household garbage or food scraps in compost piles.
Similarly rats will nest in your yard if they have water. To eliminate this problem remove any dump buckets, unused flower pots, toys, equipment & anything else in which water can accumulate after rainfall.
