Rat Treatments from SOS-Extermination
Here at sos-extermination, we have thorough expertise in rat control. When dealing with the rats at your property, we make sure to obey applicable laws and regulations and incorporate integrated pest management solutions (IPM) in our removal services. IPM is an environmentally-conscious approach to pest control, using fewer chemicals and only treating areas that target rodents. Below is a breakdown of what your rat control service may look like:
Your specialist will inspect both the interior and exterior of your home or building and look for any signs of rodent activity and any openings where rodents may be entering through.
Rat control inside may include using tracking powder in containerized stations and voids. It may also include the use of snap traps, glue boards, and/or bait stations. Control tools will be strategically placed along the travel pathway, near areas of activity, and in multiple directions.
Rat control outside will include proactively using monitoring bait or rodenticide in exterior rodent bait stations. Your specialist will add more bait when there is an increase in feeding activity or if the bait is totally consumed.
Your specialist will seal any large gaps or openings that may be allowing the rodents to enter. This will also prevent future rodent activity.
How we determine the cost of rat control
There are a number of factors that go into the costs of rat extermination, which is why an inspection prior to quoting will provide the most accurate cost. Our rat control specialists will take into account the following factors:
- Severity of the infestation.
- Size of the property.
- Commercial or residential property.
What Are Rats?
Rats are medium sized, long tailed rodents. They are members of the “Rattus” genus. Many other members of the rodent family and genera are also commonly referred to as rats, since they share numerous characteristics with the true rats.
Currently, there are more than 60 rat species in Montreal. Most of them occupy various different habitats all over Montreal. The 2 most common types living in the suburban Montreal, are the brown and black species.
A rat infestation are responsible for transmission of a number of diseases. Their feeding habits are highly destructive and the nesting behaviors can easily compromise your building’s structure, thus you need to eliminate the infestation.
How to identify Rats
Rats are some of the most common and formidable pests in the world — damaging and contaminating food, structures and human health. Although people don’t usually see the actual rats, signs of their presence are relatively easy to identify. Two primary species of rats inhabit North American homes: the roof rat and the Norway rat.
Norway rats, sometimes called brown or sewer rats, are identifiable by their stocky, gray-brown bodies. Their tails are shorter than their body length and their ears and eyes are small relative to their body. Norway rats are larger than most other rat species.
They burrow in gardens and fields, as well as beneath building foundations, trash or woodpiles. Norway rats line their nests with fibrous materials, such as shredded paper and cloth. These rats tend to inhabit the lower levels of buildings.
Roof rats, sometimes called black rats, are superb climbers that tend to nest above ground. In the wild, roof rats inhabit shrubs, trees and dense vegetation. In domestic environments, they seek out secure, elevated places such as attics, walls, sheetrock ceilings and cabinets.
They may enter homes through trees close to windows or eaves. As opposed to the Norway rat, roof rats tend to limit their geographical range to warmer climates often along the coast.
Rats are generally larger than mice. While young rats can sometimes be mistaken for mice, they can be distinguished by their disproportionately long feet and oversized head. Both rodents are capable of chewing through hard, wooden surfaces, but rat teeth marks are much larger than those of mice.
DIfferent type of Rats
- NORWAY RAT (BROWN RAT)
- SHIP RAT (BLACK RAT or ROOF RAT)
- WOODRAT (PACKRAT)
- MARSH RICE RAT
NORWAY RAT (BROWN RAT)
Norway rats are primarily nocturnal. They usually become active about dusk, when they begin to seek food and water. Some individuals may be active during daylight hours when rat populations are high.
Rats have poor eyesight, relying more on their hearing and their excellent senses of smell, taste, and touch. They are considered color-blind. Therefore, for safety reasons, baits can be dyed distinctive colors without causing avoidance by rats, as long as the dye does not have an objectionable taste or odor.
Rats use their keen sense of smell to locate food items and to recognize other rats. Their sense of taste is excellent, and they can detect some contaminants in their food at levels as low as 0.5 parts per million.
Norway rats usually construct nests in below-ground burrows or at ground level. Nests may be lined with shredded paper, cloth, or other fibrous material. Litters of 6 to 12 young are born 21 to 23 days after conception. Newborn rats are hairless and their eyes are closed, but they grow rapidly. They can eat solid food at 2 1/2 to 3 weeks. They become completely independent at about 3 to 4 weeks and reach reproductive maturity at 3 months of age.
Females may come into heat every 4 or 5 days, and they may mate within a day or two after a litter is born. Breeding often peaks in spring and fall, with reproductive activity declining during the heat of summer and often stopping completely in winter, depending on habitat.
These seasonal trends are most pronounced in more severe climates. The average female rat has 4 to 6 litters per year and may successfully wean 20 or more offspring annually.
This species can also serve as a reservoir for Toxoplasma gondii, the parasite that causes toxoplasmosis, though the disease usually spreads from rats to humans when domestic cats feed on infected brown rats.
The parasite has a long history with the brown rat, and there are indications that the parasite has evolved to alter an infected rat’s perception to cat predation, making it more susceptible to predation and increasing the likelihood of transmission.
SHIP RAT (BLACK RAT or ROOF RAT)
(Rattus rattus) is found on all continents of the earth. Although the species is believed to be native to India and possibly other Indo-Malayan countries, it has been introduced through human travel overseas to all continents.
It is most common in coastal areas because it is a rodent that flourishes in areas inhabited by humans as well as on large ships.
For this reason, these animals are often called ship rats. Some other common names for this species include house rat, black rat, and roof rat. (Rattus rattus) thrives in tropical regions but has been largely driven out of more temperate regions by Noway rats, (Rattus norvegicus).
Norway rats, are closely related to black rats, but are more successful in colder climates. However, some data show that (Rattus rattus) has been able to adapt to more extreme cold and harsh climate conditions.
Black rats are considered omnivores and eat a wide range of foods, including seeds, fruit, stems, leaves, fungi, and a variety of invertebrates and vertebrates. They are generalists, and thus not very specific in their food preferences, which is indicated by their tendency to feed on any meal provided for cows, swine, chickens, cats, and dogs.
They are similar to the tree squirrel in their preference of fruits and nuts. They eat about 15 grams (0.53 oz) per day and drink about 15 millilitres (0.53 imp fl oz; 0.51 US fl oz) per day.
Their diet is high in water content. They are a threat to many natural habitats because they feed on birds and insects. They are also a threat to many farmers, since they feed on a variety of agricultural-based crops, such as cereals, sugar cane, coconuts, cocoa, oranges, and coffee beans.
As generalists, black rats express great flexibility in their foraging behavior. They are predatory animals and adapt to different micro-habitats. They often meet and forage together in close proximity within and between sexes.
Rats tend to forage after sunset. If the food cannot be eaten quickly, they will search for a place to carry and hoard to eat at a later time. Although black rats eat a broad range of foods, they are highly selective feeders; only a restricted number of the foods they eat are dominant foods.
When black rat populations are presented with a wide diversity of foods, they eat only a small sample of each of the available foods. This allows them to monitor the quality of foods that are present year round, such as leaves, as well as seasonal foods, such as herbs and insects.
This method of operating on a set of foraging standards ultimately determines the final composition of their meals. Also, by sampling the available food in an area, the rats maintain a dynamic food supply, balance their nutrient intake, and avoid intoxication by secondary compounds.
Black rats (or their ectoparasites) can carry a number of pathogens, of which bubonic plague (via the rat flea), typhus, Weil’s disease, toxoplasmosis and trichinosis are the best known. It has been hypothesized that the displacement of black rats by brown rats led to the decline of the Black Death.
This theory has, however, been deprecated, as the dates of these displacements do not match the increases and decreases in plague outbreaks.
Rats serve as outstanding vectors for transmittance of diseases because they can carry bacteria and viruses in their systems.
A number of bacterial diseases are common to rats, and these include Streptococcus pneumoniae, Corynebacterium kutsheri, Bacillus piliformis, Pasteurella pneumotropica, and Streptobacillus moniliformis, to name a few. All of these bacteria are disease causing agents in humans. In some cases, these diseases are incurable.
A pack rat or packrat, also called a woodrat, can be any of the species in the rodent genus Neotoma. Pack rats have a rat-like appearance with long tails, large ears and large black eyes. Compared to deer mice, harvest mice and grasshopper mice, pack rats are noticeably larger and are usually somewhat larger than cotton rats.
Woodrats reach their greatest diversity in the deserts of the western United States and northern Mexico. Several species are also found in the deciduous forest of the east coast, juniper woodlands in the southwest, oak woodlands along the coastal western United States and in the Sonoran Desert, and in the forest and rocky habitats of the western United States and western Canada.
Pack rats are nest builders. They use plant material such as branches, twigs, sticks, and other available debris. Getting into everything from attics to car engines, stealing their ‘treasures’, damaging electrical wiring, and creating general noisy havoc can easily cause them to become a nuisance.
A peculiar characteristic is that if they find something they want, they will drop what they are currently carrying, for example a piece of cactus, and “trade” it for the new item. They are particularly fond of shiny objects. These two traits have inspired an anecdote about a man finding his dime replaced by two nickels. They can also be quite vocal and boisterous.
Each species of pack rat is generally restricted to a given type of habitat within its range. Pack rats live anywhere from low, hot, dry deserts to cold, rocky slopes above timberline. Pack rats build complex houses or dens made of twigs, cactus joints, and other materials.
These contain several nest chambers, food caches, and debris piles. Dens are often built in small caves or rocky crevices, but when close by human habitations, woodrats will opportunistically move into the attics and walls of houses. Some Neotoma species, such as the white-throated woodrat (N. albigula), use the bases of prickly pear or cholla cactus as the sites for their homes, using the cactus’ spines for protection from predators.
Others, like the desert woodrat (N. lepida) will build dens around the base of a yucca or cactus, such as jumping and teddy-bear chollas. The largest species, (Neotoma cinerea) has a bushy, almost squirrel-like tail.
Bushy-tailed woodrats (Neotoma cinerea) occupy a range of habitats from boreal woodlands to deserts. They are cliff-dwellers and are often found on isolated, high-elevation exposed boulder areas under a variety of temperature and moisture conditions. They require adequate shelter inside the rocks, though they are occasionally found inhabiting abandoned buildings, as well.
Bushy-tailed woodrats feed primarily on green vegetation, twigs, and shoots. Mexican pack rats eat seeds, fruits, acorns, and cactus.
Bushy-tailed woodrats are active throughout the year. While primarily nocturnal, they can occasionally be seen during the day. They are usually solitary and very territorial.
These woodrats collect debris in natural crevices, and abandoned man-made structures when available, into large, quasistructures for which the archaeologists’ term ‘midden’ has been borrowed. Middens consist of plant material, feces, and other materials which are solidified with crystallized urine.
Woodrat urine contains large amounts of dissolved calcium carbonate and calcium oxalates due to the high oxalate content of many of the succulent plants upon which these animals feed.
An important distinction to make is between middens and nests. Nests are the areas where the animal is often found and where the females raise their young. Nests are usually within the midden, but regional variations to this rule occur. When not contained within the midden, the nest is usually concealed in a rocky crevice behind a barricade of sticks.
In coniferous forests, the woodrat may build its house as high as 50 feet (15 m) up a tree.
Bushy-tailed woodrats do not hibernate. They build several food caches, which they use during the winter months.
The bushy-tailed woodrat engages in hind foot-drumming when alarmed. It will also drum when undisturbed, producing a slow, tapping sound.
This species has been know to transmit Arena virus: transmitted through the air where feces and urine are present. Hantavirus: airborne virus that can be fatal. Trichinosis, Bubonic plague, Typhoid, and Weil’s disease. Pack rats can also carry different bacteria like salmonella and parasites.
MARSH RICE RAT
The marsh rice rat is classified as one of eight species in the genus Oryzomys, which is distributed from the eastern United States (marsh rice rat) into northwestern South America (O. gorgasi).
Oryzomys previously included many other species, which were reclassified in various studies culminating in contributions by Marcelo Weksler and coworkers in 2006 that removed more than 40 species from the genus.
All are placed in the tribe Oryzomyini (“rice rats”), a diverse assemblage of over 100 species, and on higher taxonomic levels in the subfamily Sigmodontinae of the family Cricetidae, along with hundreds of other species of mainly small rodents, most of which occur in South and Central America.
In the United States, the marsh rice rat is the only oryzomyine rodent except for Oryzomys couesi in a small area of southern Texas; the only other sigmodontines present are several species of cotton rats (Sigmodon) in the southern half of the country.
The population density of the marsh rice rat usually does not reach 10 per ha (4 per acre). The weather may influence population dynamics; in the Everglades, densities may exceed 200 per ha (80 per acre) when flooding concentrates populations on small islands, In the Florida Keys, population density is less than 1 per ha (0.4 per acre).
On Breton Island, Louisiana, perhaps an atypical habitat, home ranges in males average about 0.37 hectares (0.91 acres) and in females about 0.23 hectares (0.57 acres). A study in Florida found male home ranges to average 0.25 hectares (0.62 acres) and female 0.33 hectares (0.82 acres).
Population size is usually largest during the summer and declines during winter, although populations in Texas and Louisiana may be more seasonally stable. Animals also often lose weight during winter.
Population size varies dramatically from year to year in southern Texas. In coastal Mississippi, a study found that storms probably do not cause the population to decline substantially and in Texas inundation of its habitat did not significantly influence population density. However, another study in Mississippi found that flooding did cause a marked decline in rice rat abundance.
In the northern part of its range, the species often occurs with the meadow vole (Microtus pennsylvanicus), but there is no evidence that they compete with each other.
In the south, the hispid cotton rat (Sigmodon hispidus) and the rice rat regularly occur together; water levels are known to influence relative abundance of these two species in Florida. The cotton rat is mainly active during the day, which may help differentiate its niche from that of the rice rat
The marsh rice rat is the primary host of the Bayou virus (BAYV), the second most common agent of hantavirus infections in the United States. About 16% of animals are infected and the virus is most prevalent in old, heavy males.
The virus may be transmitted among rice rats through bites inflicted during fights. It is also present in rice rat saliva and urine and human infections may occur because of contact with these excreta. Two related hantaviruses, Catacama virus and Playa de Oro virus, are known from Oryzomys couesi in Honduras and western Mexico, respectively.
An arenavirus normally associated with woodrats (Neotoma) has also been found in Florida marsh rice rats. Antibodies against Borrelia burgdorferi, the bacterium that causes Lyme disease in the United States, have been found in marsh rice rats in Virginia, Maryland, North Carolina, and Tennessee. Another pathogenic bacterium, Bartonella, is known from Georgia marsh rice rats.
