5 Best Earwig Killers
Are you short on time or just want a quick answer?
What Are Earwig Killers?
An earwig killer is any device or substance that will result in the death of earwigs when they contact each other.
An earwig killer can be an earwig trap, a bucket of soapy water, boric acid, a liquid pesticide, a granular pesticide, a dust pesticide, or an essential oil.
How Do Earwig Killers Work?
It depends on the specific earwig killer you’re using. Some pesticides attack the central nervous system, the reproductive system, their exoskeleton, their breathing tubes (called tracheae), or the digestive system.

Others will absorb the moisture in their bodies and kill them by dehydration.
All of them have one thing in common, the earwigs must come into physical contact with the earwig killer in order to be affected by it. This means they have to be used where the earwigs are.
Are Earwig Killers Effective For Killing Earwigs?
If they are used properly, earwig killers are very effective. Some can be used in conjunction with each other to provide a kind of one-two punch to attack the earwigs in several different ways. If they evade one, the other will get them.
How To Use an Earwig Killer
Granular pesticides and diatomaceous earth have to be spread either by hand or by means of a handheld spreader.
Earwigs are scavengers who eat nearly any kind of plant material so the granules should be spread across the areas where they are feeding.

Diatomaceous earth and pesticide dust should be used in wood piles and other areas where earwigs like to live, as well as in cracks and crevices around baseboards, doors, and windows where they are able to gain entrance to your house.
Liquid pesticides should be sprayed outside as a continuous barrier treatment around the foundation of your house at ground level, along the baseboards inside your house, and in crawl spaces beneath your house. Pesticide dust is also useful under houses.
Are Earwig Killers Safe Around My Pets and Children?
If the earwig killer in question is a pesticide, the answer is a definite maybe. Modern pesticides are much safer than old ones, but infants have weaker immune systems than adults and can be harmed by things that don’t bother us at all.
The younger a child is, the greater the risk of being harmed by a pesticide. Conversely, the older they are, the less risk there is.
As a general rule of thumb, keep children under six-years-old, away from the area while you’re spraying and for an hour afterward.
Some of the earwig killers that are all-natural ones that pose far less risk. Some are even edible. In those cases, there may be a question of allergies but not toxicity.
How Do You Find the Best Earwig Killer?
- Look for a substance that can be sprayed or spread evenly across the areas where earwigs live or travel. Anything that clumps or is contained in a single area, such as an earwig trap, will have an extremely poor success rate.
- A good earwig killer should be resistant to moisture. Earwigs prefer moist soil for laying their eggs and for hiding. If moisture would be a problem for your earwig killer, it won’t be very effective.
- Earwigs can survive quite handily in cold weather, which means they can attack any time of the year. Consequently, your earwig killer needs to be as long-lasting as possible so it doesn’t have to be reapplied frequently.
