Hi David,
Mr. CP in reply #27, no doubt shares a common sense message that most will never understand.
After 30 years, he knows that there is ....... and there never will be ....... no such thing as rat & mice "Extermination".
The proper term is rat & mice "Control."
Really, not any different from our friendly Political Rats ....... we can "Control", most; but, never "Exterminate" them.
Concentrate on offering D-Con to the very first rodent that enters your garage, because he/she is seeking food and/or a place to dwell.
If he/she finds either, he/she leaves a trail that other rodents can smell to lead them to either join in the banquet ..... or enjoy the comfort of their the newly found Holiday Inn.
D-con is the best "Control" factor ....... get rid of the first rodent, & their is no inviting trail for others to smell.
Rodent "Control" can be thought of as being similar & as beneficial as political "Term Limits", i.e., these first "new" rats will not stay long in your garage.
Just trying to write it as ""Food for Thought" so Forum members can remember how our friendly rodents operate.
