    Q
    I think my 10 lb dog ate a piece the size of a dime. Will it hurt him??
    A
    We recommend that you call your veterinarian immediately. We have linked the Contrac Blox product label and the Contrac Blox MSDS for you in our answer so that you may print them out and provide them to your vet.

    Q
    What is the difference between Final and Contrac?
    What is the difference and which is better? Or would you reccomend First Strike?
    A

    Final Blox and Contrac Blox are pretty comparable, though Final Blox may actually kill the rat a bit faster.  First Strike is a unique rodenticide bait that has shown high acceptance by rodents, even when competing food sources are available. The unique bait packaging around each bait allows the aroma to escape, increasing the attractiveness of the product, First Strike may be the better choice if you’re dealing with high activity and competing food sources.

    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
    Allergy Reactions to Smelling Contrac Bait Blox
    I understand the Contrac bait blocks do not give off a vapor, correct? Is it still possible for the odors from the bait when placed into an attic to weep through drywall and cause a reaction to a child (living in a room below the attic) who is highly allergic to various foods?
    A
    Contrac Blox Rodenticide do not emit any type of vapor. This product should not cause a reaction to a child unless they come in direct contact with it. Contrac Blox should be placed in tamper resistant bait stations. It will pose no threat to humans if it is used as directed.

  • Asked by Paul from Spokane

    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.

  • Asked by Cindy
    10/07/2010
    Q
    How do I know when the mice are gone?
    I have Contrac Blox throughout our house due to mice moving in with the cold weather. The first night a number of them disappeared - even from places I didn't think there were mice. Also, some were nibbled on and we trapped one mouse. How do I know if the bait worked or if they're no longer there? I don't know where the mice took the bait and there is no evidence of mice in the area except for the missing blox? Do I keep replacing the bait bloxs until they stop disappearing? Thanks
    A
    You should keep replacing the bait until the mice stop taking it. You need to place enough bait out each night so that there is left over bait in the morning. This will ensure that each mouse is able to receive a lethal dose. We also highly recommend securing the blox in a tamper resistant bait station so that the rodents cannot carry the bait throughout the house and deposit the blox in undesirable areas.

  • Asked by Daniel from Gonzales, Ca
    12/19/2015
    Q
    How long will Contrac bait stay fresh in plastic bag placed in bait box?
    A

    Once the container has been opened the Contrac has a shelf life for up to 1 year. If unopened the shelf life is up to 3 years. Bait placed inside bait stations should not be placed in plastic bags as this may deter rodents from consuming. Bait in bait stations should be replaced every 30 days or as needed for adequate rodent control.

  • 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 Mike
    07/08/2010
    Q
    Will Contrac Blox spoil quickly in the heat?
    I'm in Utah, and I'm using the Protecta bait stations (that look like rocks) with Contrac Blox inside. The daytime temperatures have been as high as 100 Fahrenheit, probably much higher inside the stations. Will this affect the toxicity and/or taste appeal to rats? Very little has been nibbled on, although each nibble seems to have produced a dead rat in the yard. We still have lots of rats which we see every evening/morning. Has the bait lost it's taste appeal after sitting in the bait stations in the hot sun for only 1 or 2 days? It appears that some of the bait has melted just slightly. Should I replace this melted bait, or any bait left in the hot sun for just a few days?
    A

    The Contrac Blox should not spoil from the heat, though as you have noticed it will start to melt if it gets too hot. We recommend that you replace the bait if it starts to mold or if insects have started to infest it. Rats are notoriously cautious and suspicious of new food items and some can take several weeks, even months before they will accept it. Are other food sources available to the rats? Try to eliminate alternate food sources if at all possible, rats will continue to feed from the "tried and true" food sources that they have used in the past.  You also need to be sure that you have offered enough bait stations to accommodate the rat population on your property as rats can also be territorial.

    Q
    How many blocks comes in the 4x4 Contrac Blox and how many blocks come in the 18lb bucket?
    A
    Each 4 lb. pail of Contrac Blox contains approx. 64 (28 gram ea) 2 in. x 1 in. x 1 in. blox, so each case would have 256.  Each 18 lb. pail contains about 288 blox.

  • Asked by Russ from El Cajon Ca
    03/21/2012
    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.

  • Asked by Sheryl from Munfordville
    12/17/2015
    Q
    Can Contrac Blox Rodenticide be stored in an unheated garage?
    A

    As a general rule we advise to store Contrac Blox Rodenticide and other rodenticides at room temperature, out of extreme heat or cold temperatures, to keep the product fresh. The food attractants in the bait will grow stale over time, making the bait less attractive to target rodents, so baits are best used within 1 year of opening. If the garage area is cool, dry, and out of direct sunlight, then this storage should be fine.

  • Asked by Mary from Reseda, Ca

    Q
    Roof Rats are stealing my bait. How long does it take for Contrac blocks to break down outside?
    I am trying to make sure how long the bait will take to biodegrade outside so I do not have to be concerned about friend's pets in my backyard. Will rain accelerate the process?
    A
    There is no defined time for the Contrac Blox to breakdown. The more moisture and direct sunlight the exposed blocks receive, the faster they will breakdown. The actual active ingredient will last until the bait has disintegrated. For future baiting it is important to secure the bait so that it cannot be carried off. If baiting in an inaccessible area you can lace the blocks on to a thick wire so it cannot be moved. If the bait is used in an exposed areas you can secure it in tamper resistant bait stations.

  • Asked by David from Bronx,ny
    09/27/2013
    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.

  • Asked by Young from Hot Springs, Arkansas
    01/31/2018
    Q
    How many Contrac All-Weather Blox does it take to kill one rat or mouse?
    A

    Contrac Blox is a single feed rodenticide. Single feed means a rodent can consume a lethal dose of Bromadiolone in one feeding, resulting in death within 1-5 days. The number of blox you will use is undeterminable because the rat/mouse has to locate and consume the bait. How much bait you need will depend on the size of the rodent population, age and health of the rodents, and how much competing food is available to the rodents.

  • Asked by Seth
    11/30/2010
    Q
    How long does the uneaten Contrac Blox last outdoors?
    A
    When please in Contrac Blox a tamper resistant bait station, it will be kept out of direct sunlight and out of the rain. Lots of rain or extreme heat will cause the bait to deteriorate faster than cool dry weather. Basically, bait that is placed into a station should be inspected every week or every other week It should be replaced if it is moldy, melted, sour or infested with insects.

  • Asked by Kathy from Orlando, Fl
    12/18/2017
    Q
    If the Contrac All-Weather Blox Rodenticide attracts rats from the neighborhood, does that mean I need to change the bait later?
    I don't want to host the rat colony on great tasting food. I will never get rid of them. Please help and explain how to handle this
    A

    Contrac Rodenticide doesn't so much attract rodents from all over as it will target rodents that are already coming onto the property other food sources, nesting supplies or water. Bait stations with rodenticides should be placed on the exterior of the home or within 50ft of the house where the rodents are already traveling. The blend of food grade ingredients will appeal to their sense of smell as they travel along their already familiar path. Use gloves when handling the bait so your human scent does not contaminate the bait and place the bait stations in the runways they are already traveling. Bait should be renewed at intervals of several days. Continuous bait availability (as with anticoagulants) is not required, but bait needs to be present long enough to allow all animals in the area to feed. The amount of bait needed is usually about one-third that used with anticoagulants, since an animal ingesting a lethal dose does not feed again.   

    You can review how to avoid the most common rodent baiting failures here.
