Electronic Bug Zapper

By Owen Jones


The hand held insect zapper is the best way of clearing the area around you of insects, especially the flying ones like mosquitoes. The hand held bug killer evaporates any insect from a mosquito to a gnat instantly on contact with a pleasingly loud, electrical 'crack'!

However, this is not to say that the indoor bug killer cannot be used outdoors, so long as it is not raining. It should be handled just like any other high voltage electrical equipment. Keep the hand held insect killer dry and please do not use it when you are standing in the pool!

Models vary greatly, but there are basically only two types of indoor bug killer: the battery operated bug zapper and the rechargeable electric bug killer. Both are equally effective at zapping insects and employ the same principle.

The hand held bug killer looks like a 'junior' tennis racket, but with three sets of 'strings', which are in fact wires. The innermost network of wires becomes live at the touch of a button while the other two grids, one on either side, are earths.

When a bug is trapped between the wires of the hand held bug zapper, it creates a short, which vaporizes it instantly with a loud crack and a flash. The electric insect killer will zap other bugs too, but they just burn instead of explode.

I have been using the rechargeable sort for about five years and am extremely happy with the indoor insect killer. In fact, the electric bug zapper has come a long way in the last few years. A fully charged electric bug killer is powerful enough to last for a few hundred swipes and will hold it's charge, when unused, for weeks without any appreciable discharge.

The rechargeable battery unit will take intensive use for the best part of a year, although its ability to hold a charge for several weeks slowly diminishes after six or seven months.

The most recent indoor bug killer I've used has a main on/off switch, a light that comes on when it is live (the brightness of this light also gives an indication of the battery's strength) and a light that comes on when it is plugged in on recharge.

The instructions suggest that it should be (re)charged for sixteen hours. I usually put it on charge over night once or twice every week or two, although the indoor insect zapper shows a marked increase in performance with only a couple of hours charging.

The latest model I've seen also comes with a powerful beam called a 'headlamp'. I have found this very useful when walking in the garden, but I'm not sure whether it's meant to attract the flies in the dark so that you can zap them if you're bored. You know, like an anglerfish.

I've used the headlamp on my hand held bug zapper for that reason too, but the headlamp uses a lot of battery power. All in all, the indoor insect zapper is a huge asset to any outdoor event. The hand held insect killer is useful to 'clean out' your bedroom before retiring; it's unbeatable for evening mosquitoes and it will clear a lunch table of wasps as well.
