Rat Control Measures
Rats like to live where people live and they can thrive on just an ounce of food and water a day. If they come upon a human-inhabited place that offers them food, water and shelter, they will stay. Rats are attracted to small spaces because they feel protected in them. If a space is small enough for rodents to access, but not for their predators such as cats and dogs, rats will make a home there. Rats can make homes in anything that provides shelter including sheds and garages, wood or rock piles, under enclosed patios and stairwells, and in unwanted items such as old water tanks, appliances, building materials and tires. Some key points for rat prevention, rat proofing, and eliminating rats are found below:
Make it impossible for rats to get into any structure. Repair all openings with a strong material (cement, metal, etc.) to prevent entry. Use screens in drains and tightly seal where utilities enter buildings. Install a metal kicking plate or heavy weather stripping beneath doors, including garage doors. If building a patio or shed on a grade, bury sheet metal 30 cm (12 inches below the grade and skirting. Check for signs of chewing damage, fecal droppings or squeaks, chirps or gnawing sounds coming from within walls and ceilings
There are four steps which are usually required in any rat control program:
• Remove food sources
• Remove potential shelters
• Rat proofing
• Eliminate rats
The bottom line to long-term rodent control is the fact that rodents must have adequate food and shelter to live and thrive. Thus, whenever there is an abundance of rats (or mice), there is usually also an abundance of food and shelter available to the rats. The removal or reduction of these factors alone via sanitation practices will have a tremendous impact on reducing rodent populations, even without the use of any rodenticides or traps.
Remove Food Sources
Remove Potential Shelters
Rats must have shelter and nesting sites in order to survive and multiply. Rats move undetected along runways which are sheltered by tall grass, shrubs or rubbish. They nest in well protected, undisturbed places; under wood piles, under improperly maintained compost bins, under patios & sheds and in unwanted items such as old furniture, appliances and vehicles.
The most successful and permanent form of rat control is to ‘build them out’, that is, make it impossible for rats to gain entrance into any area or structure where they are not wanted. All places where ‘food’ is stored, processed, prepared, or fed to pets or wildlife should be rat-proofed. If rats can be denied access to hiding places and food they can not survive.
Drains and conduits:
Use 12 mm (½ inch) screens with 6 mm (¼ inch) holes in drains. Keep them in good repair, tightly seal all areas where utilities enter buildings.
Construct concrete floors and foundations of high quality materials. In the case of patios and sheds built on grade, use sheet metal buried 30 cm (12 inches) below grade to skirt the structure. Always use screens in open doors, windows and crawl space vents. The spaces beneath doors, especially garage doors, should be checked and reduced using a metal kicking plate or heavy weather stripping. Norway rats can be deterred from climbing vertical pipes by applying a 30 cm (12 inch) band of glossy paint around the pipe or conduit.
As the Norway rat has such an enormous reproductive capacity, controlling the spread of this species means eradication, followed by year-round inspections to ensure the problem is corrected. In a community-wide rodent control program, poisoning rats is an essential part of the plan. Timing of the poisoning effort is of utmost importance. Rat poisoning methods are applied most effectively before sanitation and cleaning programs are begun to prevent out migration of rats to other areas. Also early in the spring where burrows are easily recognized and prior to initial breeding of mature rats. Forms of eradication:
Whichever method of eradication is used, it is best conducted by a professional Pest Control Operator. Look for ‘Pest Control Services’ in the Yellow Pages or online.
Precautions and Legal Implications
We strongly advise against baiting indoors as there is always a chance of rodents dying in the walls and creating a foul odour. Also, no matter what form of eradication method is used, it has to be placed where the rat will come into contact with it, ie. adjacent to a wall, behind objects.
