If we know which variables that favor invasion
In hospitals and their counterparts, a number of factors favors the existence of certain common pests such as cockroaches, flies and rodents. Many of these factors are common to other similar areas, but some of them are specific to hospitals. It costs examine all alike. How do insects and rodents can penetrate in hospitals? In food commodities and supplies: the various goods that arrive daily at the hospital may represent an important source of new cockroaches (B. germanica and P. americana) and even rodents, particularly mice (M. musculus). These insects and rodents are very often observed inside crates, boxes of diverse and varied other types of packaging, being passively transported to other locations. This is particularly true for the boxes containing food, raw or processed. Once inside the area of hospital receipts, these animals quickly disembark and seek shelter settle and proliferate. In the laundry: many hospitals, instead of having their own laundries, outsource this work and get the clothes washed and ironed properly now (bedding, towels, sheets, surgical work uniforms, etc..) This may be another way penetration of insects in hospitals along with the laundry outside. In patients belonging: not infrequently, who introduces cockroaches in hospital is the patient himself who inadvertently brings them into her personal belongings to be hospitalized. Their caretakers, usually family members who turn give 'shifts' in the rooms, may eventually be bringing certain insects including fleas. In the belongings of employees: their own hospital staff, likewise, may be bringing these insects from their homes along with their belongings on their clothing or personal. In wanderings of the body medical and paramedical staff: while transiting the premises of the hospital and out of them in the same clothes for work, medical and nursing staff can help to disseminate certain insects confectioners specifically ants and fleas. In flowers and fruits: happily circling the corridors and into the rooms of patients, where they are received with sympathy, baskets, vases and flower arrangements and trays of tasty seasonal fruit can be important vehicles of entries cockroaches and ants in hospitals. Other types of gifts intended for patients, may also be. When the flowers begin to decompose, certain insects are naturally attracted to them, increase the problem. For the groundwater pathways: through the tunnels and underground galleries of storm water drainage or served, or dried (passage of electrical wires or telephone), many insects find their way to access the facilities of hospitals. This is the case of main sewer cockroaches (B. americana); maybe scorpions come after them, their natural hunters. Rodents such as rat (R. norvegicus) also do this via their way into the main area of a hospital. Attracted by the lights: while certain insects flee and avoid light, as in the case of cockroaches, others show a strong attraction for spotlights, for example, moths, hallelujahs (which may be ants or termites) some flies, beetles, mosquitoes, etc.. A Light in the outdoor area can attract insects reasonable distances especially at night, some time in the vicinity of the premises, these insects can easily view other light sources inside the hospital and so penetrating, mostly pass simply through doors and windows left open! Once inside the premises of a hospital or the like, insects and rodents quickly located for easy dispersion conditions in the area.
