|Eco-Scientific is a multidisciplinary
environmental consulting firm engaged in dealing with wildlife management
related issues such as urban pest management. In pest management we specialize
in small rodents (mice and rats) and common insects such as German cockroach
germanica). We use pest management approach based exclusively
on proven Integrated Pest Management methodology. Our method
is particularly suited for residential setting and at an average infestation
Worldwide, from the middle 1940s to the late 1960s, the emphasis in insect control was focused on chemicals. Unfortunately one result of dependence on chemical treatments is the development of resistance to the chemicals by many pests, requiring increased amounts of the insecticide to achieve adequate control (Borror et al., 1989). Besides, being non selective and having severe effects on many beneficial organisms, using synthetic chemicals results in harmful residues being introduced to our immediate environment. They find their way into underground water table, streams and lakes eventually getting into the food chain where they might become bioaccumulated and bioamplified to excessively toxic levels with the net result of toxic pesticides having severe impact at all levels of aquatic and terrestrial ecosystem.
Integrated Pest Management (IPM) on the other hand employs a combination of pest control methods applied in coordinated manner so as to minimize the toxic chemicals use to achieve the same result with an additional component of prevention. Majority of the pest control methods employed during the integrated pest management approach are environmentally friendly and non toxic. Toxic pesticides are used only as the last resort option. The application of IPM is an educated decision based effort during which nuisance organism biology, life cycle, and its interactions with other organisms and their environment are taken into consideration in order to achieve its effective control. It also is a dynamic process adapted to prevalent local conditions based on our complete knowledge and understanding of local ecosystem components and existing biotic and abiotic stresses (Tronc commun, 2016). Finally, the IPM's prevention component results in cost efficiency not achieved by the use of periodic chemical treatments alone.
Regrettably, for many decades of urban pest management efforts employed in majority of Canadian urban centers such as Montreal the IPM has rarely been utilized. Most insect exterminations performed today still rely on toxic knock down chemical agents. These chemicals kill only a portion of the resident population dispersing the rest. Once the active component of the treatment agent is degraded with time, recolonization takes place as insects return. This requires repeated toxic chemical treatments in order to maintain pest infestations at reasonable level. In case of rodent pest exterminations frequently performed today, poisoned bait may be introduced into the environment and food chain. In addition, follow up on success of treatments is rare.
The German cockroach (B. germanica) is the most disagreeable house guest common in many urban areas of North America. Treatment of individual units within an apartment building is pointless as migration capacity of this insect is extensive. The entire building must be considered as a single unit.
After the necessary first step of detailed characterization and mapping of the infestation level in all dwellings of your building, in the cluster of affected neighboring apartment units Eco-Scientific Consultants will initiate the process of complete and therefore permanent elimination of this undesirable insect. The success of this process is primarily based on the physical elimination of insect harborage spaces, which might be accompanied by additional physical means together with an application of a non-toxic stable insecticide. The treatment will then be followed by a number of biomonitoring evaluation visits to ensure satisfactory result.
This approach is based on the IPM strategy described above and approved by academia, professional pest management associations, Québec MDDELCC (Développement durable, Environnement et lutte contre les changements climatiques) and Agriculture Canada.
There is no magic bullet, no miraculous product, only the proven IPM approach results in complete and permanent elimination of this insect since sealed cracks and crevices prevent any insect recolonization in the future.
The second, most common unwanted visitor to your buildings may be the house mouse (Mus domesticus). Mice are very social animals living in groups. Unlike insect infestations mentioned above, which normally are restricted to the kitchen and bathroom, mice inhabit entire sections of an apartment building and travel between buildings and building blocks (see the mouse biology overview). Therefore initially a more involved effort is needed. Just as it was the case with the insect above, the most humane and effective strategy in elimination of mice is the IPM strategy:
