We do not advise using Contrac Blox Rodenticide to treat for moles as it is not labeled to used for that treatment. Moles' primary food source is actually earthworms, and they stay underground to feed, so it is unlikely they would even consume a bait such as Contrac. Please refer to our guide on How to get rid of Moles to help further asisst you.
Contrac Blox Rodenticide should be applied in tamper-resistant stations to prevent non-target animals and children from accessing the bait inside. Although this product is only labeled for rats and mice, it is possible that a squirrel could be attracted to the bait matrix for consumption since squirrels are in the same family as rats/mice.
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.
We cannot recommend that you use Contrac Blox Rodenticide or any other baits for chipmunk control since these products are not registered for that use. There are food attractants in any rodenticide that may be attractive to non-target animals, which is part of the reason these baits should be used in tamper-resistant stations. We can only recommend trapping and repellents for chipmunk control. You may want to contact your local Wildlife/Animal Control Department for any other available options in your area.
The active ingredient will work as long as the shelf life. The Contrac All-Weather Blox Rodenticide contains food-based ingredients to attract the rodents which is why they will still possibly want to eat the product.
Contrac All-Weather Blox Rodenticide is required by law to only be used in tamper-resistant bait stations within 100 feet of structures and as directed on the product label. It cannot be just hung/placed out in the open or around edible trees. The fruit is going to attract the rats first as it is a known food source, to eliminate rats in the area it's really best to pick up any dropped fruit as often as possible to remove their food source.
