It is possible that a squirrel could be attracted to the bait for consumption. Although, Contrac is labeled for rats and mice, it could harm a squirrel as well since they are also in the rodent family.

Q

What is the difference between the box and the bucket of Contrac Blox?
Good morning Just wanted to ask about the difference between the box and the bucket. Would the product stay more fresh in the box vs the bucket? The last time I purchased the bucket which lasted me more than two years.

A

The Contrac Blox come only in buckets technically. You have an 18lb bucket, and then a box that contains 4 x 4lb buckets for a total of 16lbs. Some feel that being able to open each bucket when you need it allows the bait to stay fresh a little longer so some customers will purchase the 4 x 4 contai…

Some feel that being able to open each bucket when you need it allows the bait to stay fresh a little longer so some customers will purchase the 4 x 4 containers rather than the one large container of Contrac Blox. As long as the rodents are still going to the bait and consuming it they will continue to die from it and the active ingredient it contains.

Q

If the Contrac All-Weather Blox Rodenticide attracts rats from the neighborhood, does that mean I need to change the bait later?

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.

Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease. Replace contaminated or spoiled bait immediately. Collect and dispose of all dead animals and leftover bait properly. To prevent reinfestation, limit sources of rodent food, water, and harborage as much as possible. If reinfestation does occur, repeat treatment. Where a continuous source of infestation is present, establish permanent bait stations and replenish as needed.

Q

What is the shelf life of Contrac All-Weather Blox Rodenticide?
Have found an 18 lb bucket to purchase but don't want it to lose its effectiveness if not used up in a year or 2.

A

If the Contrac All-Weather Blox Rodenticide bucket is unopened and sealed, the product will last 2 -3 years, if kept away from extreme temperatures. Once the bucket is opened, it should last 1 year in normal conditions.

Q

Once consumed, will the poison in Contrac be expelled in urine and/or feces?

A

Bromadiolone, the active ingredient in Contrac, accumulates in the liver to inhibit and steadily decrease Vitamin K levels in the blood. This prevents the blood from being able to clot and will eventually lead to death. So the majority of the active is absorbed by the blood stream, and although very…

Bromadiolone, the active ingredient in Contrac, accumulates in the liver to inhibit and steadily decrease Vitamin K levels in the blood. This prevents the blood from being able to clot and will eventually lead to death. So the majority of the active is absorbed by the blood stream, and although very small trace amounts could potentially be found in the feces, it wouldn't be consistent. There will definitely be some of the waxy substance and the dye in it, but it wouldn't be enough to cause damage or be of any concern.

Per the Contrac All Weather Blox product label: "This product must be used in and within 100 feet of man-made structures constructed in a manner so as to be vulnerable to commensal rodent invasions and/or to harboring or attracting rodent infestations. Examples of such structures include homes and other permanent or temporary residences, food processing facilities, industrial and commercial buildings, trash receptacles, agricultural and public buildings, transport vehicles (ships, trains, aircraft), docks and port or terminal buildings and related structures around and associated with these sites. Fence and perimeter baiting, beyond 100 feet from a structure as defined above, is prohibited." Also, keep in mind that rodenticides like Contrac must always be used in appropriate bait stations and cannot be thrown loosely in the open.

Q

How many Contrac All-Weather Blox does it take to kill one rat or mouse?

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…

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.

Q

Will Contrac All Weather Blox attract flying squirrels to come into the attic?
Two mouse bait plastic stations containing Contrac All Weather Blox were placed in the attic. The stations were chewed by Flying Squirrels apparently to get to the Contrac All Weather Blox. Is attic use of this product advisable, acceptable, or recommended? Is attic use improper? This apparently caused a flying squirrel infestation.

Since squirrels are in the same family as rats/mice, it is possible the bait matrix in the Contrac All-Weather Blox Rodenticide could be attractive to flying squirrels also.

Since squirrels are in the same family as rats/mice, it is possible the bait matrix in the Contrac All-Weather Blox Rodenticide could be attractive to flying squirrels also. While rodenticides can be used indoors for rodent control, we typically do not recommend baiting for rodents indoors as the bait can draw insects and can also keep drawing the rodents into the home. We would recommend using the Contrac Blox in the tamper resistant bait stations outside the home around the structure. Inside the home, you can use Detour Rodent Repellent to make the attic less appealing to rodents and squirrels and use Rodent Snap Traps or Glue Boards to catch unwanted guests in your attic. If you know where the squirrels are entering you can use an Tomahawk One Way Door Excluder where they are entering the attic. This will allow the squirrells to exit through the hole, but not get back in. Exclusion Methods with Copper Mesh or Xcluder Wire are great ways to seal up holes to keep mice, rats and squirrels out.

Contrac All-Weather Blox Rodenticide should never be placed outside of a tamper resistant, locking bait station. Additionally, the bait stations should be within 50 feet of a structure.  It is made with food grade additives and will be highly attractive to unintended wildlife and pets. If you find bait blocks loose on your property, you should dispose of them. They contain waxes and additives to help the bait stay fresh for a longer period of time, so it’s possible it may withstand elements of weather for a length of time. If you are concerned your dog may have eaten some, we recommend you contact your vet ASAP, as there is an antidote available that can be given soon after ingestion that can reverse the effects of the Contrac.

I have been using Contrac bait for some time. Do I need to change brands because they may get immune to it?

You should rotate Contrac All-Weather Blox Rodenticide every 4-6 months with a bait that has a different active ingredient to prevent resistance. Fastrac or Final are great options.

Q

I have rats on my bird feeders. Is it okay to put Contrac out around the bird feeder at night and take it away during the day?
Would it be safe to put this on the bird feeder we find the rats on at night? Rarely have birds feed at night. Will it kill birds? Also will they then crawl into our attic and die? We have sealed every possible hole (except for the one they use to get into the attic) and have killed several up there with traps. Haven't caught the first one in boxes outside.

Contrac All-Weather Blox Rodenticide must be used in tamper resistance baits stations by law when used outside so it cannot be just placed out at night in the open around a bird feeder. The best thing to do with birds is to stop feeding them and use the bait in stations until the rodents are under control, otherwise you are providing a food source that they are more familar with which makes them less likely to go for the bait. After rodents consume the bait they are going to die wherever they die. To prevent this happening inside you should seal up all cracks and crevices that allow them access inside.
