• With a bug zapper, you can get rid of many different insects quickly.

• A zapper requires no personal involvement. You don’t have to worry about accidentally stumbling upon a hive or nest — or getting up close and personal with creepy-crawlies — in your quest to get rid of the pests around your home.

• While you can add chemicals to some bug zappers to increase their effectiveness, you can operate a zapper without any chemicals at all.

An insect trap lures insects to the device with light, and then a vacuum sucks them into a chamber. The bugs remain trapped in the zapper until they eventually die of dehydration.

You must empty the inner unit periodically.

An electronic zapper also uses light to lure bugs to the device. However, instead of trapping the insects, an electronic zapper electrocutes them when they touch the unit’s electrical grid. There is usually a tray at the bottom of the zapper that catches the debris.

An electric swatter is usually shaped like a tennis racket and runs on batteries. It features an electric grid that electrocutes insects when you wave the swatter at them. A swatter is portable, so you can take it with you on the go.

While nearly all bug zappers are designed for outdoor use, not all models are meant for indoor use. Look for a zapper that can be used in the area where you plan to install it.

Some models are designed for both indoor and outdoor use.

Because they use electricity to kill insects, many bug zappers emit a low humming noise during operation. When pests are killed, there may also be a popping sound. If you’re planning to use a zapper indoors, you’ll likely want one that’s as quiet as possible.

Because light doesn’t attract all flying insects, such as mosquitos and other biting species, you may want to look for a bug zapper that comes with a chemical attractant or repellent or lets you add one.

Bug zappers come in a variety of designs, but it’s important to choose a model that is enticing to a variety of flying insects.

• Light

Styles that use light attract many flying insects, such as moths, mayflies, crane flies, and beetles.

• Chemical

If you want to attract biting insects, such as mosquitos, you’ll need a zapper that lets you add chemical attractants.

• Electric

If you choose a zapper that electrocutes insects, make sure it’s designed to protect you from accidental contact, so you don’t injure yourself when it’s in use.

A bug zapper’s range is a very important feature. You need a zapper with a large enough range to cover the area where you want to eliminate bugs. However, many homeowners make the mistake of purchasing a zapper with a range that is too large, which only attracts insects from neighboring yards and areas, instead of killing the pests that are already present.

You can find bug zappers with ranges from square feet to acres. Measure your yard, and choose a model with a range that fits the area you’re trying to protect. Keep in mind that you can increase the range of a bug zapper by using chemical attractants or repellents.

Some bug zappers are equipped with a timer, which turns the device on and off on a programmed schedule.

If you don’t want to worry about forgetting to turn the zapper on or off, this can be a handy feature.

• A bug zapper is designed to attract insects in order to trap or electrocute them, so you shouldn’t place it on your deck or in your yard’s sitting area. You’ll only wind up bringing more bugs to the area where you hang out. Instead, place it at least 15 to 20 feet from where you usually sit.

• The best height for your zapper depends on the main insects you’re targeting. House flies fly low, so you should position the zapper three to four feet off the ground to snag them. For small fruit flies, you’ll want to hang it at a height of four to five feet. Hang traps five to six feet off the ground to target mosquitoes.

• If you’re using a bug zapper indoors, keep it away from the door and window sightlines, but still nearby, to handle any bugs that sneak inside. If the zapper’s light is visible from outside, it may wind up drawing pests into the house.

• You should clean out your bug zapper at least once a week. If you leave dead insects in the zapper, they may attract scavenger bugs.

• To avoid drawing insects to the very spot you don’t want them, place a bug zapper at least 15 to 20 feet from your outdoor sitting area.

Bug zappers vary in price based on type and range of coverage. In general, expect to pay between $10 and $300.

• Inexpensive: For a simple battery-operated electric swatter, you’ll usually pay between $10 and $25.

• Mid-range: For an electric insect trap, you’ll usually pay between $20 and $50.

• Expensive: For an electric bug zapper, you’ll usually pay between $50 and $300.

Q. Do electric bug zappers kill mosquitoes?
A. Unfortunately, mosquitoes and many other biting insects aren’t attracted to light. However, that doesn’t mean a zapper isn’t capable of killing mosquitoes. If they fly close enough to the device, they’ll suffer the same fate as insects attracted to the light.

Q. How large should a bug zapper’s range be?
A. The proper range for a bug zapper depends on the size of your yard. If you purchase a zapper with a range that’s larger than your property, you’ll wind up attracting insects from neighboring yards instead of controlling the population you already have.

Q. What features can make a bug zapper more effective?
A. A timer can be very handy. It will turn on the bug zapper so it has time to work before you actually go outside. Depending on what insects you want to target, you may also want a bug zapper that lets you use chemical attractants to help lure bugs that aren’t drawn to the zapper’s light.
