More Help

So, here are a few suggestions to  help 
"Send 'em packing":

1. Remove all packrat nests or middens in the area.

2. Clean out all debris in the engine compartment.

3. Power wash the engine compartment and apply "Purple Power" or  Biokleen to fully erase the lingering scent that the packrat has left.  Be careful to avoid sensitive electronics in the area. 

4. Park the car in an area away from walls, buildings, and other hiding places with at least 10 feet of clear area around the car.

5. Remove all food sources such as pet food, bird seed, and hay and old fast food wrappers. Note that
packrats like haypiles, especially when stored on wooden skids. It gives them a secure place to hide.

6. Don't park the car near piles of boxes, garden tools, or any place where the packrats can find cover from predators.

7. Trim nearby shrubbery or cactus up off the ground. This eliminates their hiding places.

8. Use a live trap such as Hav-a-hart to "thin the herd." Placement of the traps is important here. Place the traps along walls or garage doors where you see evidence of pack rat activity, usually marked by their "pellets".

Yes, they are rather amusing to watch,
but their food droppings also attract pack rats!
This also applies to those nice little packets
of seeds that we leave out for the birds.

10. In some severe cases it may be necessary to add other means of protection.
Sonic devices are an option when all else fails.  Coyote urine is also said to be an effective deterrent. Some people have been known to place flashing Christmas lights under the car. Even though some of these things may be considered ineffective, they are certainly worth trying!

Dryer sheets. They don't work, the odor does not repel them.
Moth balls. 
They're toxic to both humans and animals.

Poison bait. 
It's a bait! It attracts them and in turn kills their predators and is a danger to your pets. It may also take several days for the poison to work giving them time to re-invade your car.

By following all the above steps you can get your packrat problems under control!

On occasion we have observed severe problems with very aggressive or determined rats. They may have marked their territory, are hormonally driven, and have a strong drive to preserve their adopted home.  In these cases a broader approach is necessary to persuade them to nest elsewhere.

Unfortunately, getting rid of pack rat problems is not a one step process, but it is often a continuing process of control and elimination.  Some female pack rats have been known to deliver up to five litters per year with each litter having as many as five young. The offspring may open their eyes between 10 and 12 days after being born and are usually weaned between 14 and 42 days. After around 60 days, most become sexually mature
CHICAGO-Some of America's biggest metros have unleashed a chilling-and seemingly effective-new killer in the unending urban war against rats: Dry ice.
Sanitation officials in the nation's third largest city told USA TODAY they recently launched a pilot program at four Chicago parks to test the effectiveness of dropping chunks of dry ice-frozen carbon dioxide-into burrows to try suffocate rats as the dry ice sublimates from a solid to a gas.
Chicago began the experiment with dry ice in late August, following Boston, which became the dry ice pioneer when it launched its pilot in March, and New York City, which launched its test program in May.
"When I first brought up the idea, people around here thought I was cuckoo for Cocoa Puffs," said Leo Boucher, assistant commissioner for Boston's Inspectional Services, which consulted with Chicago as it launched its dry ice pilot. "But we all became believers. It works."
The odorless gas in solid form-commonly used by stagehands to create an artificial fog effect and by merchants trying to keep perishables from spoiling-also can be deadly to small animals at high concentrations.
Earlier this week, USA TODAY observed Chicago sanitation department workers at one of the city's oldest parks scoop chunks of smoking dry ice into a burrow before quickly covering the entry and exit holes with dirt and newspaper to stop any rats from escaping as the -109.3-degree Fahrenheit gas dissipated. Sanitation workers say they treat burrows during morning hours, when rats are less active and most likely to be huddled inside the burrows.
The asphyxiated dead rats then decompose in place and out-of-sight of city denizens who count the disease-carrying vermin among the vilest of indignities of urban living.
While the program is only a few weeks old in Chicago, officials there say it shows promise.
"We are seeing 60% fewer burrows in areas where we are using the dry ice," said Charles Williams, Chicago's streets and sanitation commissioner. "It's more environmentally friendly, and it's very humane on the rodents as well."
The dry ice experiment comes as many big U.S. cities are experiencing an explosion in rat complaints from residents, according to a USA TODAY analysis published earlier this year. Among the cities with the biggest spikes in complaints are Boston, Chicago, New York and Washington, D.C.
