To protect individual vehicles you may want to consider using T-Rex snap traps beneath the vehicle and resting on the vehicle tires overnight. Tamper-resistant rodent bait stations loaded with bait such as Fastrac Blox will help reduce the level of mice and rats if there are more on the property to a more manageable level. These products can be purchased together in our Rodent Kits: http://www.domyownpestcontrol.com/rodent-kits-c-21_405.html.
We do also have rodent repellents which you could use around the area where a vehicle is parked to help deter rodents from this areas. Rat Magic is a granule repellent that could be spread easily around the area (do not use indoors such as in a garage).
Please contact your Local Sanitation Dept for guidelines in your area on disposal of unused Fastrac All-Weather Blox.
Almost every bait station on the market will be large enough and designed to house any bait block including the Fastrac and Contrac blox. This would include the Evo Ambush for either of those baits if you choose to use them.
Using Fastrac in tamper resistant bait stations is a great option for outdoor mouse control. Please take a few moments to look over our Mouse Control Guide for more information on treating and preventing this pest.
Fastrac Rodenticide is a great fast kill rat bait that can be shipped to California.
After a rat consumes a lethal dose of the bait of any rodenticide it is possible that the animal can get into an area that is inaccessible making removing the carcass impossible. This can lead to a terrible odor and a secondary insect infestation. While you can bait indoors using a tamper resistant bait station, we strongly discourage it. Baiting outside the structure and using snap traps/glueboards indoors is suggested. If you choose to bait inside, please place rat bait inside tamper resistant bait stations and place the stations out of reach of non-target animals and children.

There is not an antidote available for Fastrac Blox, but there is a Vitamin K1 antidote available through your local vet for Contrac Blox and Final Blox.
When using Fastrac Blox along with any other rodent bait, there is no way to pinpoint where the rodent will die. They could, unfortunately, die anywhere - under couch, in walls, etc. and there can be an odor. The only way to guarantee where the rodent dies is to use traps such as the T-Rex Traps or Victor Tin Cat Mouse Traps.
