Discovering an insect in your home often triggers a strong impulse to eliminate it immediately. And who can blame you? Some insects carry harmful chemicals and deliver painful, even deadly, stings. But before you squash those horrifying-looking centipedes hiding in your toilet, consider this: they may actually be doing you a favor.

Centipedes, those squirming critters with numerous legs, may give you a shock when you spot them in your house. However, they have been silently protecting your home from other tiny insects. These unique centipedes, with around 20 legs, have been serving as your home’s invisible pest control system, keeping cockroaches, spiders, silverfish, bedbugs, and ants at bay. With their ravenous appetite, they devour almost every arthropod they come across.

But don’t worry, this doesn’t mean you should welcome centipedes en masse into your home. A small population of one or two centipedes should be appreciated as a gesture of gratitude for their pest control efforts. Instead of squashing them, simply let them go about their business or gently relocate them outside to enjoy some leaves.

Resisting the urge to squash every bug you encounter inside your house has its advantages beyond sparing centipedes. It prevents you from inadvertently releasing hundreds of baby spiders into your home or encountering other nasty insects with deadly consequences. Here are a few of the dangerous insects you should hope never to encounter indoors:

Bullet Ants

As their name suggests, bullet ant bites feel like being shot. These ants are one of the largest ant species and are commonly found in the jungles of Paraguay and Nicaragua. Avoid their painful bites by taking preventative measures.

Botfly Larvae

Botflies, though harmless themselves, can bring about trouble. The female botfly lays its eggs under the skin of many animals, including humans. As the larvae develop, they burrow deeper into the skin, causing infection and significant tissue changes. Some people claim to feel the larvae crawling inside their skin, which can be extremely unsettling.

Fleas

Flea bites can cause itching, irritation, and even skin infections. These blood-feeders are a nuisance, so it’s best to prevent flea infestations altogether.

Fire Ants

Fire ants are infamous for their painful stings. They can repeatedly sting their victims, causing painful white pustules that may last for weeks. Certain species of fire ants release venom that can trigger allergic reactions in some individuals.

The Kissing Bug

The kissing bug, known for transmitting the trypanosome cruzi parasite through its bites, is responsible for thousands of fatalities each year. Prevention is key to avoiding this deadly bug.

Giant Japanese Hornets

Giant Japanese Hornets are the largest hornets, reaching up to 2 inches in length. Their sting is lethal and claims the lives of approximately 40 people annually. It’s best to steer clear of these formidable insects.

Tsetse Flies

Sleeping sickness, caused by the bites of tsetse flies, contributes to approximately 500,000 fatalities in Africa each year. Proper protection and prevention methods are crucial in avoiding these deadly flies.

Killer Bees

Killer bees, as their name suggests, are aggressive and attack in overwhelming numbers. Their sheer quantity poses a threat, making encounters with them potentially lethal. Taking precautions is essential if you live in an area where killer bees are present.

Driver Ants

Driver ants are formidable creatures with powerful mandibles. They attack with force and can dispatch numerous animals during a single raid. While they mostly target other insects, they do have a nasty tendency to bite people.

Mosquitoes

Mosquitoes are not only known as the deadliest insects but are thought to be one of the deadliest organisms on Earth. They can transmit diseases such as encephalitis, West Nile virus, malaria, and yellow fever, which collectively cause up to 1 million fatalities annually. Protecting yourself from mosquitoes is crucial in minimizing the risk of these deadly illnesses.

So, the next time you come across a centipede in your home, consider sparing its life as a token of gratitude for its hidden pest control efforts. And remember, not all insects are enemies, but some require caution and preventative measures to ensure a safe and peaceful living environment.
