We use Contrac Blox because it always works, unlike trapping, and is very inexpensive as compared to trapping. Trapping requires multiple visits and may not achieve 100% eradication, especially when large numbers of rodents are present. Contrac Blox has a low chance of secondary poisoning. Rodents do not have to eat much of the bait and then it is passed quickly through their system. The small amount of active ingredient in the liver of the rodent would require target animals to eat the entire carcass and many of them to get to toxic levels. Pets tend to be well fed and are unlikely to eat enough whole dead rodents to cause a problem, assuming they have access to that many. In the unlikely event that a pet is poisoned the antidote is Vitamin K, which all emergency vets have on hand. There is an organic rodent bait, Terad D, but we do not use it as there is no antidote.

As far as primary poisoning, which is a more dangerous situation, rodent bait is only placed in tamper proof bait stations or secured in areas where they cannot be accessed by non target animals.

The solution to rodent problems is closing up the points of entry on your home. We look for anything that is ¼” or larger to seal up. This exclusion must be done after we know that all of the rodents are out of the home. It most situations this can be done two weeks after the initial bait application.

Any time poison is used there is an element of danger for pets. This product, if used correctly, offers a low chance of this and is very effective in dealing with these pests that carry disease and cause damage to property. If there is a situation in your neighborhood that you think may be contributing to rodent problems please contact the City of Austin’s Rodent and Vector Control hotline, 512-978-0370.
