Yes, both the 4lb and 18lb buckets of Contrac Blox utilize the same label.
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.
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.
Unfortunately Contrac Blox is only labeled for rodents like rats and mice. 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.
We do not advise using Contrac Blox Rodenticide to treat for moles as it is not labeled to used for that treatment. Moles' primary food source is actually earthworms, and they stay underground to feed, so it is unlikely they would even consume a bait such as Contrac. Please refer to our guide on How to get rid of Moles to help further asisst you.
The chances of secondary poisoning by chickens consuming the feces left behind by rodents that consumed Contrac Blox is extremely slim. Normally animals have to consume multiple entire rodents in order to ingest enough poison to have any effects. Unless the chickens are getting direct access to the poison itself there should not be any issue if they consume a few pellets here and there.
We cannot recommend that you use Contrac Blox Rodenticide or any other baits for chipmunk control since these products are not registered for that use. There are food attractants in any rodenticide that may be attractive to non-target animals, which is part of the reason these baits should be used in tamper-resistant stations. We can only recommend trapping and repellents for chipmunk control. You may want to contact your local Wildlife/Animal Control Department for any other available options in your area.
By law Contrac Blox Rodenticide needs to be used inside a bait station, we would not recommend to toss loose blox in the drop ceiling. We would recommend using traps instead.
We do not recommend baiting for rodents indoors as the bait can draw in insects. We would recommend snap traps or glueboards indoors. Rodents will go back and forth looking for food and harborage supplies. We recommend to also try and find out where they are entering and seal up those areas.
There are approximately 288 blocks of Contrac Blox in the 18 lb pail.
Contrac Blox come in two different sizes. Each 4 lb. pail contains approx. 64 (28 gram each) 2 in. x 1 in. x 1 in. blox.
Each 18 lb. pail contains about 288 blox.
Contrac Blox Rodenticide and other similar products do have active ingredients that are toxic to fish, however secondary poisoning from a rodent that consumed the bait is generally only a concern with birds of prey or other scavengers that would actually eat the rodents who had consumed the bait. Per the SDS: "Do not apply this product directly to water or to areas where surface water is present or ot intertidal areas below the mean high water mark. Runoff also may be hazardous to aquatic organisms in water adjacent to treated areas...Bromadialone water solubility is extremely low (<0.1mg/l)."
We would recommend not using rodenticides near the pond or in a way that may contaminate the pond. You could use snap traps inside a bait station in areas outdoors where you do not wish to use rodenticides, such as the EZ Snap Rat Bait Station.
Contrac Blox would be a good option to replace the Terad3 blox. Be sure to continue using bait stations so that no non-target animals come in contact with it. Secondary poisoning is very minimal with Contrac and an antidote to the poison (vitamin K1) is readily available.
The question you are referring to may be outdated, so we will be sure to look into that. Contrac previously was not labeled for voles at all, but the labeling has changed in the past couple of years to include meadow voles (the most common vole species) in addition to rats and mice. Before this change was made, Kaput Rat & Mouse Bait and Kaput Combo Mini Blocks were the only rodent baits that we carried that were labeled for voles. Either Kaput or Contrac will work to eradicate voles, but as you said, if the population is very large, complete control will take some time. It is a good idea to continue to make the bait available as long as the voles are still eating it. We have a vole control guide on our site here that may be helpful.
We apologize, but the term "triangle stations" is a little vague. We can tell you that the Contrac Blox are a standard size and will fit into most rodent bait stations, including triangle-shaped stations like the Protecta RTU Mouse Bait Station.
There are many reasons why rodents may not be attracted to a bait such as Contrac Blox. One very common reason is that the bait is not fresh; baits should be used within 1 year of opening, and stations should be changed every 30 days for the best acceptance. You should also be sure to wear gloves when servicing bait stations and handling rodenticides. This not only protects the person handling the bait and stations from contaminants and possible disease, but it also keeps human scent and oils off the bait so as not to deter the rodents from it.
It can be difficult to locate competing food sources. Mice will travel up to about 10-20 feet for food from their nesting site, while rats will travel much farther, 50-100 feet from their nesting site. Bait placements should be close enough together to allow easy access to the bait. Keep in mind also that if this is a service call, then you have not been there to monitor the sanitation all the time, so there could be trash or other food sources that have been left out. All food storage areas, food containers, areas around applicances, and trash receptacles should be checked for rodent activity.
If you have used fresh bait multiple times and are unable to locate and competing food sources but still see new rodent activity, then you may want to consider using a different bait. Just like people, rodents can prefer one food over another. Soft Baits such as First Strike have very high palatability and are great to rotate with something like Contrac.
If the Contrac Blox have been used properly within bait stations, then there should be no concern about the bait contaminating any edibles. The anti-coagulant active ingredient in Contrac is not absorbed systemically into plants.
Contrac Blox can be toxic to animals if enough is consumed, although an antidote, Vitamin K1 is readily available from your vet. If you believe your pet consumed any amount of this product, it is important to contact your vet or pet poison control as soon as possible.
Contrac Blox Rodenticide is not labeled for possums but if they were to eat enough of it it could harm them. 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 possum from being able to work the bait free from the rods.
Contrac Blox Rodenticide are not labeled for voles. We recommend Kaput Rat and Mouse Bait which are labeled to treat for Voles.
