How long do the Contrac Bloxs stay fresh if stored properly in the bucket?

Does the product fade in time due to opening and closing lid to use product? How effective is this product compared to the individual contract pellet packets?


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 and Contrac Place paks are essentially the same product just in different shapes and packaging. Contrac Place Paks are very useful for treating mice that love to tear open and gnaw through packaging and the pellets are small enough for them to hold and consume, but the product would eliminate both rats or mice. Contrac Blox work well for both rats and mice by providing them with a large gnawing surface.
