Insect Killers for pest control of mosquito: Uv-a lamps, mosquito traps, bug zappers


The mosquito deposits its eggs in a dark, humid place where it can shelter and mature safe from danger of dehydration.

When the baby insect is born, it can only leave this environment in the absence of solar rays, since these would dehydrate and kill it.

Nature has therefore programmed it only to emerge at night, when the only rays to guide it are ultraviolet.

Experiments have shown that during the first hour of their lives, a very high percentage of newly born mosquitoes fall into mosquito traps (bug zappers) because of the attraction of ultraviolet, and after the first two hours nearly all of the insects ended up being caught.

This attraction reduces as the insect matures, until it is completely gone when the female needs to lay her eggs: during this period, she is attracted mainly by the smell and heat of human and animal bodies. When the female is finally ready to lay, instinct guides her to seek out narrow, humid and cool places, where she knows the eggs are protected from predators and from the sun’s rays, and can be kept In the best conditions for hatching.

Thus it is evident that an effective campaign of pest control can only be mounted at the beginning of spring, to get rid of the insects as soon as they are born.

By switching on ultraviolet mosquito traps around the protected location of the eggs every night and switching them off in the morning, the population of young mosquitoes is destroyed so they are unable to breed.

The result of an effective clearance operation is that in high summer, the population of adult females thirsty for blood will be nonexistent or at least limited to ones coming from far away which have not been disinfested.

Low pressure mercury vapour tubes. This uv-a lamps are made of a fluorescent plated glass tube containing two electrodes. Luminous emissions of uv-a lamps are comprehended between 300 and 400 nm, with peak at 365 nm. For uv-a lamp is meant a light source that issues electromagnetic radiation mainly in the range of the ultraviolet and, to a negligible extent, in the field of visible light.


Optimal placement requires that the electric insect killers and bug zappers be placed in an area some way from places frequented by humans.

In order for the attractive action to be effective on diurnal insects, the bug zappers must be placed in half shadow rather than in full light.
This placement of bug zappers is preferable so as to avoid competition between the rays emitted by the appliance and solar rays, which, being more powerful, would nullify the action of the appliance.
uv-a lamps source placed in a low-light environment will always attract insects that come near it.

Even moonlight or artificial light from uv-a lamps can interfere with the action of the electric insect killer.
It is thus best to place the mosquito traps in areas screened from such light sources. If more appliances are placed in the same area, they need to be distanced according to their operating range, as indicated in their respective instructions for use.

If, for example, an electric insect killer has an operating range of 10 metres, place the second at a distance of 20 metres.

Avoid placing the appliances for pest control near to light-coloured walls, as the emitted light will reflect off the surface and disturb the action of the appliance.

Avoid placing the appliances for pest control near draughts, which could interfere with their action.

Place the appliances for pest control at a suitable height. Best results are obtained 2-3 metres from floor level.
