Contrac is a single feeding anticoagulant bait in pellet form that has superior acceptance by Mice and Rats. It is a pellatized bait made with an advanced formulation process that produces a fresher, better compressed pellet for improved weatherablity. Contrac contains Bromadiolone, which is less toxic to non-target animals in primary and secondary poisoning than other chemicals.


Simply Contrac place packs down where rodents travel. Rodent will gnaw through pack and ingest poison.


Though rodents may consume a lethal dose in one feeding, bait shyness is not a problem because mortality occurs a few days after consumption. An antidote, Vitamin K1, is readily available and there is a time factor for treatment.
Contrac are colored blue and authorized for use in federally inspected meat and poultry plants.


Determine areas where rats or mice will most likely find and consume the bait. Generally, these are along walls, by gnawed openings, in or beside burrows, in corners and concealed places, between floors and walls, or in locations where rodents or their signs have been seen. Protect bait from rain or snow. Remove as much alternative food as possible.


  • RATS: Apply 3 to 16 ounces of bait (usually at intervals of 15 to 30 feet) per placement. Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease.
  • HOUSE MICE: Apply 1/4 to 1/2 oz. (1-2 level tablespoons) of bait per placement at 8- to 12- foot intervals. Larger placements (up to 2 oz.) may be needed at points of very high mouse activity. Maintain an uninterrupted supply of fresh bait for at least 15 days or until signs of mouse activity cease.
  • RATS AND MICE: 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.

    Really works!!

    By Michelle on 08/23/2005

    Thank you for the Contrac rat packs. I like to put them under the house and other places also. They kill the rats and don't leave a bad smell. It works really well.

    Contrac Rodent Place Packs

    By Rd on 08/18/2010

    I placed this on top of my kitchen counter on the sides where it can not be easily reached. I do not know how many rodents are there but so far I only saw 1. I saw 2 black pellets (which is the poop of the rodent) among the Contrac rodent pellets which is obvious that the rodent ate the pellets. After that I do not see rodent tracks anymore! When rodents eat this they die with no bad smell.

    Mouse' es out of control

    By Phil on 11/02/2011

    Verified Purchase

    I was feeding mice from a 5 gallon pail of poison I got from a store here in Minnesota and it did not do one bit of good. I friend in Chicago sent some of your contrac rodent packs, 7 to be exact and it about wiped out all mice in my buildings. I just bought the 192 box or what ever size it is you sell and thank you for solving my problem.

    Extremely Happy

    By Kim on 05/12/2010

    I received the shipment in less than a week. Threw the unopened packs around my basement and a few days later went downstairs to see if the rats were eating the poison. To my surprise, some of the bags were gone entirely! Most were opened with some or a large portion of the pellets missing. I think my huge rat problem is just about gone! I highly recommend this product and the company.

Is it recommended to open the Contrac Rodent Place Packs or leave them closed?

I have the Contrac Rodent Place Packs, and I have read all the instructions for use. I'm just not sure where it says to open the packs or not. I have NOT opened them, but I've placed them closed in cupboards and closets today.

You can use the packs closed or open. In most cases, you will use the Contrac Rodent Place Pack closed and let the mice or rats chew through the wrapper. If you were directly treating a rodent burrow, you would open the pack and just place the pellets into the burrow to avoid having the rodent throw the pack out.

Are Contrac Place Packs poisonous to dogs and cats?

A neighborhood dog ate some Contrac Place Packs. We are trying to call and my bug people aren't answering. Is this poisonous to dogs?

Contrac can make a pet sick, but every veterinarian has the antidote.  Contrac is actually a good product if a pet gets into it because the antidote is vitamin K and easily accessible.  You should definitely call your vet immediately and probably have the dog looked at just to be safe.

And if I put out poison it will not make them want to chew more water pipes? correct? I did trap a large field mouse with very long teeth, looked like he could not have closed his mouth.

The size of teeth will vary from mouse to mouse, just like our teeth are all unique.There are four basic steps to eradicating mice.


Mice may live alone or in groups. In order to assess the severity of the problem and to get a better idea of where to bait and trap, you will first need to perform a thorough inspection of the premises. What you'll want to look for are any signs that mice are present, including: droppings, tracks, gnaw marks, urine stains, live or dead mice, and mouse sounds. Take note of where the highest concentration of signs are found so that you can concentrate further preventative and control measures in those areas.


Sanitation is probably the most important measure of prevention and control in combating any pest or rodent problem. While good sanitation will not eliminate hosue mice, poor sanitation will certainly attract them and allow them to thrive in great numbers. Remember that the house mouse must have access to a ready supply of food, water, and nesting materials to thrive. Sanitation measures should focus primarily on reducing these stores. To reduce house mouse populations, try the following sanitation measures:

  • Store any bulk food items in large metal containers or other airtight containers with tight fitting lids, rather than bags or boxes that can easily be gnawed through.
  • Remove clutter such as paper and cardboard that mice might use to build their nests
  • Remove undesirable vegetation around your home such as grass clippings and weeds
  • Keep dog food or other pet food stored in a Rubbermaid container overnight.


Mice can enter homes and other structures through openings as small as ¼ inch. They may also enter through ill-fitted doors, windows, or screens, and air vents that are not in sound or working order. While you will not reasonably be able to compensate for every possible entry, you can greatly reduce the ease of entry for mice (and thereby, reduce the population size) by taking the following measures:

  • Seal any openings ¼ inch or larger with caulk, wood, mesh, or other appropriate materials
  • Floor drains and sewer pipes should have tight-fitting grates with openings less than 1/4 inch in diameter.
  • Make sure that all doors, windows and screens fit tightly in their frames and repair those that do not. (It might also prove helpful to cover edges of screens with sheet metal to prevent rats from gnawing around them.)


While you are preventing future mouse population growth through inspection, sanitation, and exclusion, you will also want to begin working towards elimination of the population that is already present through trapping and baiting.

  • Trapping is the preferred method of control in homes where relatively few mice are present. The following are some advantages of trapping when compared to baiting:
    • 1) Trapping does not require the use of harmful poisons
    • 2) Trapping allows the user to know whether the mouse was killed, whereas with baiting the mouse will wander off and die somewhere else
    • 3) Trapping eliminates odor problems by allowing you to dispose of the carcass.

Use enough traps to eliminate the house mice quickly. Traps should be placed flush with walls in areas of highest travel (as determined by Inspection).

  • Baiting. This method uses poisons, or rodenticides, to attract and kill mice. This is a great supplementary treatment to trapping when you are dealing with larger rodent populations, or for outdoor populations. House mice sniff out the bait and return to feed upon it continuously until the poison kills them. A few baits are even strong enough to cause death with a single feeding. You will know the bait is working when the bait is no longer being consumed. This means there are no more mice to feed on it because they are dead. Always be sure that fresh bait is available continuously until mice stop feeding.

Can I get the Contrac Rodenticide in a smaller quantity, perhaps 50?

I don't need this large a quantity (250?). I am an individual and I am afraid that the shelf life might expire before I could use them all.

Unfortunately due to new rodent laws that were passed in June of 2011, certain anticoagulants can no longer be sold in smaller quantities.  They have to be sold in 8 or 16 pound increments.  This is a regulation passed by the EPA and has nothing to do with us.

Just wondering, why you are not following the EPA's new guidelines regarding rodenticides and consumer packaging. These were set into place June 4, 2011.
All companies that sell rodent baits are allowed to sell their complete inventories. After the inventory with the old labels have been spent, the new guidelines will be followed. This was written into the EPA guidelines. We always follow current guidelines and laws that are in place by the EPA.
