Mosquito Control

Mosquito Control

Mosquito ControlThere are many ways by which mosquitoes can be more or less effectively controlled. The thorough screening of houses to keep them out is a desirable practice and is also of value as a protection against house flies.

Nettings over beds for the same purpose are often used where entire houses are unscreened. Out of doors, veils covering the head and gloves for the hands are often necessary in places where these insects are extremely abundant.

Protective materials rubbed on exposed parts of the body are also often used and various substances have proved of value for this purpose. Among these are spirits of camphor and oil of citronella, which seem to be the favorite substances used in this way. Smudges will keep away mosquitoes where the smoke is, and burning insect powder in a room stupefies the insects so that they fall to the floor and can be swept up. Other materials for use in a similar way are also available.

Destruction of the larvae, pupae and eggs is the most direct way in which to control mosquitoes in large numbers, and many methods for accomplishing this have been tried.

As mosquitoes develop only in water, the removal of the places where they can breed, such as the drainage of marsh land, filling up small pools, hollows in trees containing standing water, and all such situations, will accomplish a great deal. The drainage of the salt marshes of the New Jersey coast and elsewhere has resulted in a marked relief from the attacks of mosquitoes in those localities. Where the water can not be drained off, covering it with a film will suffice to destroy the eggs on the surface, larvae and pupae at, or coming to, the surface for air, and any adults which may alight on the water to lay their eggs. Rain-water barrels and cisterns for storing water for use can be screened, and ponds may be stocked with small fish (sunfish or top minnows) which feed voraciously on these insects.

The catch basins of sewer openings are usually favorite breeding places for mosquitoes and these must be given attention, along with cesspools and any tin cans or other receptacles containing rain water which can be found.
