There are a number of alternative methods of rodent control other than rodenticides but you still need a measure of care and competence to obtain the most effective results. All non-chemical methods have risks or are not a sure-fire way to get results, as this depends on using the methods properly. Both live and dead rats and mice can spread infectious diseases and parasites. Of course, it is vital with every method chosen to do the basics of excluding rats and mice from food and access to shelter, making sure they cannot return.
Here are a few chemical free rodent control devices:
1) Cats and dogs – Our pets are not effective controllers of rodent populations in neighborhoods, well-fed pets in the home environment will have little motivation to hunt or access to many of the places the rats and mice frequent in a home. Rats and mice can even thrive in the presence of pets, living off their food and water, particularly when they are kept outdoors!
2) Live traps – These have a spring or electronic release catch that closes the door on a cage or container when a rodent triggers the mechanism capturing it live.
3) Electrocution traps – These are enclosed traps that sense an animal entering, close the entrances and send an electric charge through a metal plate on the floor of the container that kills the rodent.
4) Glue or sticky boards – They are boards of varying sizes covered with very sticky glue, often mixed with food smells, designed to immobilise an animal that walks on them.
5) Rodent repellents – Ultrasonic rodent repellents 200- 91,000Hz.There is some evidence that ultrasound have a limited effect when used in very small spaces.
6) Spring/ snap traps – Traps that are designed to kill rodents with a spring release. Caution is required as children, pets and wildlife can set them off.
