    Q
    How long does it take a rodent to die after consuming Contrac Blox?
    I live in a row how with a 1st floor extension (slab on grade), and I thought I had a rat problem, Used Contrac in the Basement, and I baited the ceiling by wire stringing 3 blocks and letting a length of wire hang from the ceiling. Every day, I would check to see if the wire moved. Recently, I noticed that the wire moved about 8 inches into the ceiling and then I heard subsequent scratching later in the day. Now, I keep baiting the ceiling and I keep seeing the wire moving! (It's been about 3 days). I hope it's only one rodent as I heard scratching only in one specific place. Questions. 1. Do rats stop and gnaw or do they drag the food back? I had 3 blocks wired in series and now I can't even see them in the ceiling in the hole that was made. 2. How long does it take for rodent to die? I know that it depends on ingestion, but, if a rodent takes a bite of the bait, will it die eventually? It's been driving me crazy! I will have to eventually crack the ceiling open and look for points of entry, as it is a point of curiosity. It has just turned really cold as well. Any suggestions?
    A
    After eating a lethal dose of Contrac Blox it can take 3-7 days for a rodent to die. Rodents will sit and gnaw the bait if it is held in place so that they cannot simply carry it away. If the bait is not secured there is a good chance the rodents will carry it back to their nesting area. We recommend you read our articles How to get rid of Roof Rats and also How to rodent proof your home. Because you live in a row house we also recommend speaking to your neighbors and sharing this information. Without their cooperation you may not be able to control the rodent population around your home.

    Q
    I suspect that my bait station with Contrac is attracting racoons; will the Contrac kill a racoon?
    Bait stations are placed in the yard to deal with rats. Bait stations will be found 3 to 4 feet from where they were placed and bait is gone. I do not want to attract racoons or other critters. Should a different bait be considered or should I not bait the traps for some period of time?
    A
    The Contrac can kill a raccoon if it ate enough, but it would have to eat a large amount.  It doesn't sound like your stations are secure at all to the ground or to some other structure.  You can use liquid nails and affix the station on a 1 x 1 foot paver you can buy from home depot.  This well prevent them from being moved.  Also, if you make sure the bait is secured on the rods, and the station is secure, it should prevent the raccoons from being able to work the bait free from the rods.

    Q
    secondary poisoning concern with wildlife & contrac blox.Also, how effective in killing voles?
    I garden near wildlife habitat & considering using contrac blox for dusky footed wood rats & for a vole population explosion-which can be very destructive to all sorts of plantings.What about birds of prey,snakes,foxes,etc.-if they eat a recently poisoned rodent?How effective is it for voles?
    A
    Contrac Blox is not labeled for voles or for dusky footed wood rats. Contract Blox is only labeled for Norway Rats, Roof Rats and House Mice. Also due to the new EPA regulations, when used outdoors rodenticides can only be used immediately adjacent to or within 20 ft of a structure and the bait must be contained in tamper resistant bait stations. There is a chance of secondary poisoning if an animal eats a rodent that has been killed by rodenticide. Terad3 rodenticide is usually used in areas where secondary poisoning is a concern because it has a reduced risk of secondary poisoning. No matter what bait you choose you will still need to remove and dispose of any carcass you find to help eliminate the risk of secondary poisonings. You should know that most products that were labeled for voles have now been removed from the market by the EPA. In most cases it is recommended that you use old fashioned wooden snap traps placed directly in the voles travel paths to help reduce vole numbers.

    Q
    Should I be concerned about secondary poisoning when using Contrac Blox?
    I am worried the neighbors cat may eat a poisoned rodent. I will be using Protecta Bait Stations.
    A
    The risk of secondary poisoning with Contrac Blox is very minimal. A rodent only consumes a very small amount of bait at a time and passes it very quickly only keeping a smaller amount in their liver until they succumb to the effects of the bait. A cat would have to actually eat 20-30 rodents that have consumed the bait for it to have an effect. In most cases well fed domesticated animals will not actually eat a mouse or a rat that they come across. Instead they will play with it, chew it and then leave it behind.

    Q
    Is it safe to place this product inside floor vents? (I saw a mouse go through my floor vent)
    I killed a mouse and two weeks later I saw another one. The area where I stay was once a wooded area and they built townhouse. Please help because I hear noises in the floor vents!!!!
    A
    You cannot place the Contrac inside the vents. You can place the Contrac inside tamper resistant bait stations near the vents and in places where you have noticed activity. The mice and or rats must come out of the vents to get food so they will eventually find the bait. The alternative would be to use snap traps or glue boards in areas where you have noticed activity. By using snap traps and or glue boards you will know exactly where the rodent has died and make removal easy.

    Q
    Will horses eat Contrac Blox and will it hurt them?
    I put some in a ceiling of a horse barn where the rats are nesting and I am finding some in the stalls. The rats are carrying them out of the ceiling and dropping them in the stalls. I was wondering what would happen if a horse ate one and if he would?
    A
    Horses and rats are both mammals and the bait will have the same effect on both of them. Of course a horse weighs a lot more so it would need to consume more of the bait to receive a lethal dose. We are not sure if horses would be attracted to the bait because it has not been tested for horses. Bait should never be tossed into spaces because of a rats tendency to move it around. In the future you should use piano wire to string the bait onto and then nail the wire down so the rats can not take off with the bait (for spaces that inaccessible to non-target animals and children only). For places that are accessible to children and non-target animals the bait should be placed in tamper resistant bait stations which will also prevent the rat from removing the bait.

    Q
    Can Contrac Blox be used to rid ground squirrels?
    A
    Unfortunately contrac blox is only labeled for rodents.  Therefore we cannot recommend that it be used for ground squirrels.  We do not have any products that are labeled for squirrels specifically other than live catch traps.

    Q
    How does the Contrac bait kill mice
    A
    Contrac Blox is an anti-coagulant which means once the mice eat this product they begin to bleed to death from the inside.  The mice first become sick, and then grow tired and weak and pass in their sleep.  It can take anywhere from a 1-5 days depending on how much the mice have eaten.  They do not need water for the product to work.

    Q
    how much Contrac Blox Rodenticide will it take to kill a horse?
    We had our horses get into our shed and they eat a bucket of bait. there are 4 horses and we don't know how much bait was left.
    A
    Generally speaking a horse would have to consume their body weight in Contrac blox for it to harm them. Please make sure to contact the manufacturer Bell Labs 800-323-6628 and the Horses Vet for follow up with the horses ingestion of Contrac Blox.

    Q
    Does Contrac Blox Attract Mice?
    Mice got inside our heat pump outside and did some damage. If I place a bait stations around the heat pump, will the Contrac Blox odor attract mice to the bait station and the heat pump? Thanks.
    A
    Yes, the mice and rodents in the area will be attracted to the Contrac Blox as they are made of a variety of very attractive food based ingredients for the rodents to want to feed on. Any rodents looking for a food source would want to go to the bait in the stations. Please let us know if you have any other questions.

  • Asked by Gregory from Las Vegas Nv
    08/13/2013
    Q
    Tackling a rat problem in an area accessible by kids, pets?
    I recently moved to Las Vegas and rented a nice ranch style house in the North sector of town. In this subdivision, all of the houses are well maintained and most have swimming pools, in-ground sprinkler systems, palm trees and the back yards are separated by 6ft to 8ft concrete walls. My house is enclosed in the back. I have a pool and built in BBQ area and the front yard is open. I've seen coyotes and fox traipsing around in the area but no major birds of prey. While sitting in the pool the other night a friend and I noticed shadows on the surrounding wall so we flashed a light and were shocked to see rats using the tops of the walls as mini-highways. I have to assume the rats are migrating out from the sewer systems at night because of the cooler temps and to search for water/food. Most people have vegetation, trees along the back walls of their property. Vegas is a very hot desert climate, so water is #1 on the survival list. My first thought was that the pool water was attracting the critters. Then I realized that most people have BBQs, decks and eating areas in their back yards, so water may be only one of the factors. I am inclined to use food poison pellets because trapping doesn't seem to be as effective as bait. Problem is, I'm not sure which is best for this scenario. Friends and family (and their pets) visit and of course the pool and back yard has trees, bushes, rocks on the outer edges and is the focal point for get togethers. My worry is that a child or pet will inadvertently come in contact with the poison. Appreciate your recommendations.
    A
    Contrac Blox is usually preferred in areas with pets and/or children as there is a readily available antidote in the event of accidental ingestion and because of the reduced risk of secondary poisonings (if one of your dogs were to eat a poisoned mouse). Final Blox is used when a fast clean out is needed as it will kill the rodents a bit faster than the Contrac Blox. Final Blox does have a higher risk of secondary poisoning but also has an antidote. We always recommend that you use tamper resistant bait stations that will help stop accidental poisonings of non-target animals and children no matter which bait you select.  Please take a moment to read our article for baiting tips for rats

  • Asked by Bk from Avon Lake
    08/24/2013
    Q
    Should I consider switching the Contrac bait so that the mice don't get "bored" with the same one?
    A
    There are some instances when rodents can be resistant to a certain active ingredient in a bait and there may be instances where the rodents will avoid the bait all together (bait is old or spoiled, too many alternate food sources are available). We recommend changing to a bait with a different active ingredient so that you will have fresh bait and you can avoid any issues with resistance.

    Q
    I live in northern Ohio. Should I maintain baiting stations during winter?
    A
    As rodent activity increases in the winter, we suggest that the Contrac bait be changed every 30 days to avoid the bait getting molded.

    Q
    How often should I change my Contrac Bait?
    A
    It is recommended to change Contrac bait out every 40-60 days if not eaten. Very cold or warm temperatures will mold or sour the bait faster.  There are some instances when rodents can be resistant to a certain active ingredient in a bait and there may be instances where the rodents will avoid the bait all together (bait is old or spoiled, too many alternate food sources are available). We recommend changing to a bait with a different active ingredient every 4-6 months so that you will have fresh bait and you can avoid any issues with resistance.
