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.
The key is to control rat populations, not individual rats.
The most commonly found rat pest in United States is the Norway rat (Rattus norvegicus).
Norway rats are also polygamous and form colonies of many males and females.
Rat droppings are small, dark, cylindrically shaped, and are about one-half inch to three-fourths inch long with blunt ends.
They may be frightened by sound-producing devices for awhile but they become accustomed to constant and frequently repeated sounds quickly.
Since roof rats rarely dig burrows, burrow fumigants are of limited use; however, if they have constructed burrows, then fumigants that are effective on Norway rats, such as aluminum phosphide and gas cartridges, will be effective on roof rats.
That is very costly! Do the job ONCE by a wildlife operator, NOT A PEST CONTROL COMPANY, get it done, and you'll be rat-free forever.
All anticoagulants provide excellent roof rat control when prepared in acceptable baits.
Distinctions must be made as to which rodenticide (registered product) to use, the method of application or placement, and the amount of bait to apply.
Resistance is of little consequence in the control of roof rats, especially with the newer rodenticides presently available.
They prefer to consume fruits (sometimes referred to as the “fruit rat” or “citrus rat”) and nuts, although roof rats are omnivorous and will feed on almost anything available to them.
Because of the diseases they can carry, you should also check up on the equipment that you will need to safely trap the rats without any risk to your health.
Trapping is an effective alternative to pesticides and recommended in some situations.
This is why traps and bait stations may be avoided for a day or two.
They have also been found living in sewer systems, but this is not common.
Hantavirus pulmonary syndrome is transferred via inhalation of rodent urine, droppings or saliva.
Anticoagulants (slow-acting, chronic toxicants).
A few instances of first-generation anticoagulant resistance have been reported in roof rats; although not common, it may be underestimated because so few resistance studies have been conducted on this species.
Their presence is typically detected by the occurrence of their droppings, holes chewed into bags and containers, and chewed nesting materials.
A vegetation-free margin around the grove will slow rat invasions because rats are more susceptible to predation when crossing unfamiliar open areas.
When practical, remove extraneous vegetation adjacent to the crop that may provide shelter for rats.
The latter two were ineffective for roof rats.
If you have heard noises in your walls or attic, chances are you have rats.
This is a great supplementary treatment to trapping when you are dealing with larger rodent populations, or for outdoor populations.
Historically, infected fleas have transmitted serious plagues from rats to humans.
As their name suggests, roof rats may be found in elevated areas such as trees, rafters, attics and roofs.
The 5 to 8 young in the litter develop rapidly, growing hair within a week.
They prefer to live in high places, but may live in a variety of environments.
The Norway rat produces six to eight litters of six to nine young per year.
