Why are Rodenticide/ Rat traps often ineffective?
Rats become aware of rodenticide after few rats are poisoned and also recognize traps upon seeing trapped rats. They also communicate the danger to other rats. Hence it becomes impossible to catch or kill more than few rats by these methods. The ineffectiveness of Rodenticide/ Rat traps is evident from the amount of damage rats create in spite of its usage. High breeding rates and comparatively low killing rates of rats due to its fast awareness to traps and poisons stand as the main reason to the affect.
