I have a small bricked in patio 18x18 with a planterbed all the way around....for 18 years i have fought rats on and off and they never go away entirely no matter how vigilant. One of the problems is that this poison will never kill an entire group. I think it is a combination of things - but two things have become clear to me...rats are smart and this productis too watered down. The poison that is sold to regular consumers is weak. The good stuff (white powder version) that they walk in and then groom eachother back in the next, is the same but at a much stronger concentration...BUT IT IS NOT SOLD TO ANYONE WITHOUT A SPECIAL CERTIFICATION. This results in a situation in which you can't get enough of it to do the job because pest control guys put out only a little which has the effect of increasing their business. Sorry to be so cynical...but after 18 years of this problem...i am confident about what i am saying.
We are sorry to hear you are having such a hard time controlling the rodent population on your property. Please don't be discouraged in your efforts! Contrac is not a consumer product, it is a professional product used by pest control companies. Having said that, we would recommend you use a product that has a much faster kill to wipe out the rat population quickly as you seem to live in a high population area. Fastrac works within 12-24 hours. Contrac by comparison can take up to 7 days. You should also make a few environmental changes to make your home less favorable to these rodents. You can learn more about these changes by reading our Rat Treatment Guide and our Rat prevention Guide:
