Q

How long is the potency of the Contrac if a mouse ate this bait that laid out for six months will it die?

A

Contrac bait should be stored at room temperature and replaced every 40-60 days in the bait stations because it contains food based ingredients. The bait could mold or sour in the hot or cold months (should be replaced every 30 days during the summer and winter) and may be less palatable to the mice…

The bait could mold or sour in the hot or cold months (should be replaced every 30 days during the summer and winter) and may be less palatable to the mice. It should eradicate the mice if they consumed enough of the bait.

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 ca…

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.

It 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 few hours to a few days depending on how much the mice have eaten. They do not need water for the product to work.

Q

Will you modify the Contrac so it stops killing owls and other predators?
I am concerned about the numbers of raptors dying from secondary poisoning after eating poisoned rodents. The anti coagulant in Contrac blocs will also kill owls, and other raptors as well as mammalian predators that eat poisoned rodents. Will you change the formula so it is environmentally friendly and doesnt kill much needed predators?

A

While we are not the manufacturer of the Contrac blox we do carry another product that is for use in areas where secondary poisoning of predatory birds are an issue. Terad3 rodenticide is usually used in areas where secondary poisoning is a concern because it has a reduced risk of secondary p…

Below is a few helpful hints for baiting Mice. Always use fresh bait. Rodents will avoid old, moldy, or insect-ridden baits. When baiting for mice, a good measure for distance between placements is 8 to 12 feet apart for light to moderate infestations. Heavy or severe infestations may require placements of 4 to 8 feet.

As a rule, many bait placements containing smaller amounts of bait are more effective in mouse control than a few placements containing a lot of bait.

For heavy infestations, use the maximum number of bait placements indicated by the label.

Bait stations should be placed where mice are likely to encounter them during their routine travels, between harborages and food sources.

Corners are "hot spots" for bait placements since mice tend to spend a lot of time in darkened corners.

Attempt to locate "favorite feeding locations" (indicated by a high concentration of rodent signs-droppings, tracks, odors, shredded paper, etc.) and replace existing food sources with bait stations in these locations.

Always use mouse-sized bait stations, not the larger stations designed for rats.

Mice often live above or below their food sources, in attics or basements, so bait placements should not be limited to a single level of the infested structure.

Mice develop preferences for certain types of foods and baits. If there appears to be bait avoidance, try placing 3 or 4 different bait formulations (pellets, place packs, bait blocks, liquid bait) to see if the mice will prefer one formulation over another.

If a bait placement remains unvisited upon inspection, try moving the placement five feet in another direction.

Q

Will Contrac attract rats from the neighbourhood?
How attracted rats are to the Contrac Blox? A pest control guy suggested that it wouldn't be a good idea to preventatively use baiting station with Contac. He said that it may attract rats that otherwise wouldn't be around the house. Is this right? Would it really attract rats from, say, 10-20 yards away? 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.

Q

Does Contrac give off any vapors when placed inside the home, and if so, are the harmful to humans?
We placed 11 contrac blocks in the attic of our house to get rid of mice, and are concerned about possible effects of the vapors on us. We also placed several stations baited with Contac in the kitchen and basement. Is this safe for humans?

A

Contrac is a block rodenticide that does not release any vapors. If applied in tamper resistant bait stations it should pose no harm to humans if applied as directed.

Contrac Blox should be used within about 1 year of the purchase date. The active ingredient within the product would most likely stay effective long after 1 year but the food ingredients or the attractants will start to degrade and will no longer be attractive to rodents. Just opening and closing the lid of the storage container would not cause the product to lose its efficacy, but storing the product without a lid could cause it to mold or otherwise degrade.

Contrac Blox is a single feed rodenticide. Single feed means a rodent can consume a lethal dose of Bromadiolone in 1 feeding therefore resulting in death within 1-5 days. The number of rodents that 1 block will treat is undeterminable. Place 3 to 16 Contrac Blox (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. 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.

For a rodenticide, we would recommend Contrac Blox. It is a single feed kill. It comes in an 18 lb. pail. We would recommend putting these in rat bait stations, such as Protecta Rat Bait Stations.

For a rodenticide, we would recommend Contrac Blox. It is a single feed kill. It comes in an 18 lb. pail. We would recommend putting these in rat bait stations, such as Protecta Rat Bait Stations. If you are in CA, we would recommend Fastrac Blox. Although they are not a single feed kill, they still will work wonderfully. For spiders, we would recommend using Bifen IT. This can be sprayed indoors and outdoors. It does have a residual of about 90 days indoors and 30 days outdoors. Indoors, it needs to be sprayed in the cracks and crevices and along the baseboards. Outdoors, this product can be used around the perimeter, in the lawn, on shrubs, trees and on flowers. This product should be used on edibles.

Q

Insects eating Contrac Blox Rodenticide
I have Contrac Blox Rodenticide inside Protecta Evo Ambush bait stations, and it appears that insects are eating the bait. I put these out last year, and I didn't notice any signs of insects eating the bait at that time (I change the bait every 4 months). Recently, all of the bait was gone, and I replaced it and rechecked the next week to find them covered in insects. Any ideas/suggestions?

A

Insects are trying to fatten up for the winter. It is not uncommon for insects to be more attracted to rodent bait like Contrac. We recommend to sprinkle Niban Bait around the outside perimeter of the bait station to keep the insects out.

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.

Q

How lethal is Contrac Blox if injested by a canine?
Just wondering if my math is right each blox contains about 1.4mg of Bromadiolone? and bromadiolone is lethal at 10mg per 1 kg body weight? so a 10kg dog would need to eat roughly 70 blox to be fatal? 0.005% of (28 grams) = 1.4 milligrams

A

Each blox of Contrac is 28 grams which equal 2800mg. If your pet ate an actual blox, I wouldn't take the chance of figuring it out because the minimum amount could be lethal. It would be best to take your pet to the vet and have him/her take a look and/or administer the antidote which is Vitamin K1.
