Q

Is it safe (within the label and the law) to place Contrac blox above a drop ceiling in a restaurant?
Is it within the label and the law to pop a few ceiling tiles out of a drop ceiling in a restaurant and scatter a few blox around for rats? I am aware that I would have to deal with the odor. I have been told that the blox must be secured in a station of some sort but the label says nothing about that.

A

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.

Q

Is there a difference between "voles" and "meadow voles"?
I'm confused since there is a discrepancy in the description of Contrac and in a question/answer from Mike in Caseyville, Il. In the description of Contrac it includes "meadow voles", yet in your response to Mike, you say to use Kaput. Which is preferred? We have been using Kaput and it is being eaten, but not sure of its effectiveness, since they seem to keep eating the bait. However, we may have a large infestation and it will take some time to eliminate all of them. Do you still recommend the Kaput over Contrac?

A

The question you are referring to may be outdated, so we will be sure to look into that.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 …

The question you are referring to may be outdated, so we will be sure to look into that.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.

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.

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

How quick does Contrac All-Weather Blox work?
I believe we have 1 rat in our basement. I've found it's burrow in our wall. Set a contrac blox outside the borrow, disappeared overnight. Placed two more in the same spot and they were untouched for 2 nights now. Also, snap traps that were constantly having the bait taken off them and not triggering are also no longer being emptied of bait. Is it possible the rat died after 24hrs and only eating one block? Don't want to risk taking that part of the wall down and disturb his burrow to have the rat move to a new location and die if I'm not quick enough to catch him once I open the wall.

A

The Contrac All-Weather Blox Rodenticide is an anti-coagulant, which means that once the rat has eaten this product, they begin to bleed to death from the inside. The rat first becomes sick, and then grows tired and weak and passes in its sleep. It can take anywhere from a few hours to a few d…

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 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. 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.

Q

I have rats under my strawberry plants. Can I use Contrac?
I have a good crop of strawberries but holes under foliage are blocked with ripe strawberries. There are numerus berries both ripe and not ripe that are severed from plants. The plants are vigorous but are looking like a kid may have picked the fruit, plants a little beet up. Garden is well fenced with 4 ft high hog wire with 2"x3" openings. I think I must have a rat problem but since the darned thigs are very smart I'm not sure how to eradicate them. Is there another creature that may be doing the damage? I have raspberries and blueberries that may also have critters burrowing under them I have put out motomoco for mole control.

A

There are many kinds of rodents, birds, or other small animals that could be eating a fresh crop of fruit. A mesh or fence opening that is 2” x 3” is large enough for mice, rats, voles, chipmunks, and more to come and go as they please. You may consider denser fencing, or using rodenticide in b…

There are many kinds of rodents, birds, or other small animals that could be eating a fresh crop of fruit. A mesh or fence opening that is 2” x 3” is large enough for mice, rats, voles, chipmunks, and more to come and go as they please. You may consider denser fencing, or using rodenticide in bait stations around the structure or along fencelines (as long as it is within 100 feet of the house) such as those in our Rodent Baiting Kit. If you are able to inspect more for signs like droppings, then you may be able to determine what is there and use appropriate traps for them. Be sure, also, that you are picking fruit as it is ripe and removing fallen fruit from the ground. You may consider a repellent such as Nature’s Defense Organic Animal Repellent around the edge of the garden, but you may not be able to overcome the habits these animals have already developed.

Q

What happens if Contrac All-Weather Blox Rodenticide contacts water?
When this product comes into contact with water, does it create a poisonous gas or toxic fumes?

A

Contrac All-Weather Blox Rodenticide would not release any type of fume or gas if it contacts water. Water would just cause the product to be unattractive to rodents as it could mold and sour due to exposure.

Q

Can I use Contrac Blox Rodenticide for rats in my attic?
I have rats in the attic. Can I use this? Will they die in the attic and how likely is it that the rats actually live up there instead of just coming in every now and then?

A

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.

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.
