Rats are one of the most difficult problems framers have to face the whole year round.
For traps, you can dig holes in different locations around the farm. The holes should be 30 to 40 cms (14 to 18 inches) wide and 50 to 60 cms deep (23 to 28 inches).
Fill the bottom of each hole with water.
Rub the sides of the holes with a mixture of dry ground fish and coconut oil that provides an attractive odor around the hole.
The smell of the oil mixed with the fist attracts rats.
When rats try to eat the food, they will fall into the water at the bottom of the hole. They will be trapped in the hole until you get rid of them. (PCARRD FARMNEWS, 1992)
