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.

You can learn more about opossum control by reading our article Opossum Control. By law, all rodenticide baits including Contrac must be applied in tamper-resistant bait stations.

The unique bait packaging around each bait allows the aroma to escape, increasing the attractiveness of the product, First Strike may be the better choice if you’re dealing with high activity and competing food sources.

Contrac All-Weather Blox Rodenticide can be used indoors but only if they are secured in tamper-resistant bait stations. Using tamper-resistant bait stations keep kids and pets from accessing the bait but also, secures the bait blox to help with monitoring activity. If the bait blox are not secured, the rodents will take the blox to the nest, therefore, making it difficult to see if they are consuming the bait. I have included the instructions per the Contrac Blox product label regarding the number of blox that should be used over certain linear footage. RATS: Place 3 to 16 bait blocks (at intervals of 15 to 30 feet) per placement in infested areas. Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease.
MICE AND MEADOW VOLES*: Place 1 block per placement. Space placements at 8- to 12-foot intervals in infested areas. Two blocks may be needed at points of very high activity. Maintain
an uninterrupted supply of fresh bait for at least 15 days or until signs of
mouse or meadow vole* activity cease.

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.

The risk of secondary poisoning with Contrac Blox is very minimal. A rodent only consumes a very small amount of bait at a time and passes it very quickly only keeping a smaller amount in their liver until they succumb to the effects of the bait. For expample, a cat would have to actually eat 20-30 mice that have consumed the bait for it to have an effect. In most cases well fed domesticated animals will not actually eat a mouse or a rat that they come across. Instead they will play with it, chew it and then leave it behind.

You should not put Contrac Blox or any other pesticides inside air vents or other similar systems within your home. Rodenticides must be secured in bait stations or otherwise in areas that are inaccessible to people, pets, and non-target animals. If rodenticide is not secured, then the rodents can hoard the bait and may move it to a location where it becomes accessible to non-target animals. We recommend using traps for rats that may be indoors. We have more tips on how to eliminate rats from your home in this guide.

Q

Can you use Contrac Blox and First Strike together in the same rodent station?

A

While there should be no issue using the Contrac All-Weather Blox Rodenticide and First Strike in the same station (meaning they won't interact with each other), it would be better to use one at a time and rotate between them every 4-6 months instead to prevent resistance buildup to either.

Recommendation for living nextdoor to a chicken coop.
Your bait is fantastic rats love it. I'm in CA so a friend gave me some blox. My neighbors have 27 chickens, food and water containers placed in the open sporadically. I have had rats for about 1 month in my backyard shed, also under the deck, under the house, and now in the garage on the other side of the house. I used traps and have caught about 15 rats, mostly small ones. But now that the neighbor found a nest under a pallet, they scattered, mostly to my house. There are to many for traps. HELP!
