When food, water, and shelter are available, rat populations can increase and will increase very quickly. Seemingly overnight a seemingly small rat problem will become one that is out of control. Doing your own rodent control you may discover that mechanical traps and even baiting may not be enough to contain, control and stop a rat infestation.
Keep in mind; you should never touch a rat that is dead with your hands. The easiest and safest way to remove a dead rat is to place a plastic bag over your hand pulling the rat into the bag and disposing of both into a sealed outside garbage receptacle. This way you will not come in physical contact with the rat.
There are many products available to you in the market place for rat control. These include glue boards, spring traps, ultrasonic devices, and baits. You are probably already aware that glue boards are messy, and the slightest amount of dust on them will render them ineffective. Spring traps work well, but placement and baiting material can be a problem. Ultrasonic devices are not effective for rat control. At first the rat is frightened by the unusual and unfamiliar sound, but very quickly adapts and will continue with business as usual, contaminating your food and damaging your home.
Interesting, Pepsi or Coke that is freshly opened and poured into a dish will kill a rat. Once they ingest one of these, the carbonated gas begins to build up. Since rats cannot burp, the gas eventually builds up inside to the point where it will suffocate the rat. It only works if the pop is fresh; if it is flat (lost its carbonation) then you have simply provided another food source for the rat. Since the Norway Rat nest in burrows underground, it is possible to drown them by placing a garden hose into the hole and flooding its nesting area.
