I am looking for mouse repellent for use in our substation and communications buildings.

Would probably use inside and outside.

How often does this product need to be reapplied?

Is this available in larger quantities?

MOUSE REPELLENT will generally last 1-3 months per application depending on the local environment where it’s applied. Outside, it will usually dissipate over 1-2 months for sure. Even in dry climates. If the region where you plan on using it is moist or subject to a lot of rainfall, it may only last 1 month. If you intend on using it such a location, consider making the installation with GRANULE GUARDS to help protect the product and extend the length of time it’s effective.

Inside applications out of direct rainfall and sunlight could last 3 months or longer. Be advised it will release a smell when used inside and can be detected but my guess is these substations aren’t manned so it’s probably not an issue.

The largest size currently is the 28 lb PAIL. But we also carry a snake repellent which has the same exact ingredients. This product is available in large 236 lb Tubs though we don’t list this size on line in our cart. You can see the 28 lb pail and here are links to their respecitve labels:



As you can see, they are identical in composition. The large size is commonly acquired used by professionals who use it for various pest control services. It’s the same exact material but just has a different target animal on the outside label. Cost per 236 lb tub is $400.00 but we do extend our 5% online ordering discount to call in orders for this big size which drops the price to $380.00 or $1.61 per lb compared to $3.39 per lb for the 28 lb tub.


I have pack rats eating my outdoor cushions.  Can this be used on fabric without problems?

Clearly rats like to chew things as explained in our RAT CONTROL ARTICLE. This is quite normal out in the wild but when they are allowed to exist in close proximity to a building, chances are high that the building itself or something around or inside the building will become a “chew” target. My guess is there must be something close by which is luring them in like bird seed, pet food or some other abundant food source. If rats are frequenting your yard for food, chewing and gnawing will be a problem.

To stop them from chewing something specific, give it a good dose of ROPEL SPRAY. This bad tasting agent will get them to stop and move on to something more palatable. And take the time to treat anything else close by you think they might target. Likely objects rats like to chew include house siding, small trees, automobiles, garden hoses and most any yard furniture.

Ultimately you might have to either restrict the amoun of food available in the area to help cut down on the rat activity. If this can’t be done, one of the trapping methods used to reduce the local population might be in order. Rats chewing furniture cushions isn’t nearly as bad compared to what can happen once they target house wiring and other sensitive objects.
