Control
The control of insects can be made first through good hygiene practices in the hospital
environment. Favorable results can be obtained by using screens in the windows of
kitchens or places where they can obtain food. Pesticides are applied periodically in openings,
dark places, and baseboards—the usual hiding places. An effective chemical product,
piretróide, acts upon the neuron membrane, causing a chemical imbalance in the
concentrations of sodium and potassium.
A specialist team should be established to control vectors in the hospital environment.
Collaboration of all hospital departments promotes the success of the control
program.This team should relate to the local health authorities. If outside companies are
utilized, they should be specialized and registered in their areas of specialization.
The risks of pesticide application without appropriate criteria include low efficiency,
human toxicity, and increased resistance of the insects. Effective control of vectors in the
hospital environment requires a knowledge of the vector’s habitat, alimentary habits,
reproductive cycle, and other factors that could serve as vulnerability points.
Finally, the basic strategy of intervention should consist of treating the existent breeding
places, expelling the insects, and impeding their return to these places for recolonization.
