Washtenaw County, Michigan Rat Control Services
Rodent entry elimination: We see many attempts by handymen, pest control companies, and Washtenaw County, Michigan rodent extraction companies that do not include the removal of any roofing material. Often the prevention includes the emptying of a can of foam into the void. Without the removal of roofing material, there is no assurance that rodent entry will be eliminated. When we encounter these substandard attempts, we must first remove the previous application. When this includes foam, the extraction of the foam takes longer than the application of our wire prevention product.
Rodent elimination by those who are not insured exposes you, the Washtenaw County, Michigan homeowner, to unnecessary liabilities. It is in your best interest to request proof of insurance for worker’s compensation and public liability before work begins on your roof. It’s doubtful that you will find these companies or individuals carry such insurance. Those who do not often work in this environment typically cannot afford expensive roofing insurance.
Gnawing holes - Gnawing holes from Roof rats are about 2 inches or more in diameter and will have rough edges.
Observation Rats are not usually seen during the day unless disturbed from their protective harborage or because of intolerable competition from other rats.
Citrus trees, having very low hanging skirts, are more prone to damage because they provide rats with protection.
Mice can enter an opening as small as 3/8" wide.
Rats themselves - if you see one rat, there's a good chance there are a bunch more hiding in nests or burrows that you can't see.
High-frequency sound-producing devices are advertised for frightening rats, but almost no research exists on their effects specifically on roof rats.
A new second-generation anticoagulant, difethialone, is presently being developed and EPA registration is anticipated in the near future.
These devices must be viewed with considerable skepticism, because research has not proven them effective.

Tunnel boxes or bait boxes specially designed to expose a layer of toxic powder will reduce potential contamination problems and may actually increase effectiveness.
It actually makes it worse, because the rats are multiplying, dying, defecating, destroying insulation, chewing wires and chewing air ducts, while you wait for your next service.
Snap traps are actually the very best way to do it.
In some situations in which the rats have been eliminated, cats that are good hunters may prevent reinfestation.
The fumigation of structures, truck trailers, or rail cars should only be done by a licensed pest control operator who is trained in fumigation techniques.
In some agricultural areas, roof rats cause significant losses of tree crops such as citrus and avocados and, to a lesser extent, walnuts, almonds, and other nuts.

Roof rats are not accomplished swimmers and are not usually found in sewers.
They may be frightened by sound-producing devices for awhile but they become accustomed to constant and frequently repeated sounds quickly.
In tree crops, some cultural practices can be helpful.
Their tails are longer than the rest of their body and are uniformly dark colored.
Roof rats can also enter openings in walls, eaves and roof from the branches of trees.
Setting a trap to collect a few specimens may be the only sure way to identify the rat or rats involved.
They may live in the landscaping of one residence and feed at another.
When droppings are seen, it is a good practice to remove those droppings and later inspect to see whether new droppings were deposited.
Most pest control companies set rat traps, perhaps squirt some flammable expansion foam at very obvious holes, and then put you on a monthly service to remove the rats that are still getting in to your home.
If roof rats are seen exposed, it often indicates their hiding spaces are all filled by other rats or that they have been disturbed, such as by construction.
The advantages of trapping when compared to baiting include: 1) Trapping does not require the use of harmful poisons; 2) Trapping allows the user to know whether the rat was killed, whereas with baiting the rat will wander off and die somewhere else; 3) Trapping eliminates odor problems by allowing you to dispose of the rat carcass.
Roof rats have a strong tendency to avoid new objects in their environment and this neophobia can influence control efforts, for it may take several days before they will approach a bait station or trap.
