Having beneficial insects is a great way to boost your garden and get the most from it. However, some of these insects are deemed dangerous to humans. Many of us do not know this, because a lot of times, the venom or other poison they give off is not strong enough.

You have heard about the common ones, the spider – stay away from them or they’ll bite but there are a few insects on this list that you might not have known are beneficial. This is because these are thought of as dangerous, and rarely ever as helpful. Find out how they’re helpful and see if you should be keeping some of these dangerous insects in your garden.

If you’re wondering what these insects are, then you’ve come to the right place. Here is a list of some dangerous insects that can harm or hurt you, but are, really great for that garden you’re growing.


Spiders are one of the most dangerous insects you’ll find hanging around anywhere. They are also one of the insects on the list that you would also not be afraid of. Spiders can bite you, but most of them will not poison or harm you.

Spiders are great at keeping other predators away from gardens because they eat almost anything smaller than them that moves. They help to keep pests under control that would otherwise eat through a garden.

Some spiders that you can expect to find within the garden are yellow garden spiders, brown house spiders, brown recluse, black widows, orb weaver spiders, wolf spiders, crab, and jumping spiders, barn spiders, and so many other spiders.

It’s best to stay covered when you’re in an area where the spiders might be present. Generally, spider bites do not hurt but they will itch with time and swell a small amount. By protecting your arms and legs, especially the ankles; you’re reducing the chances of being bitten.


Believe it or not, mosquitoes, the tiny things that bite and annoy you, are beneficial to ecosystems. They help to pollinate all types of plants. They’re also a great food source for bats, spiders, birds, and others.

Mosquitoes can spread diseases, making them an insect you don’t want to be next to. However, since they help the beneficial insects and other animals around your garden, you might not want to get rid of them.

Using mosquito repellent that has DEET in it, covering up as much as possible during the low light hours when they come out more, and using citronella can help to reduce the chances of being bitten by mosquitoes.

Fire Ants

Fire ants are scary-looking ants that you generally don’t want to cross paths with and upset. When angered, they start to bite, and this can sting. Medical attention is sometimes needed when fire ants are involved.

However, they’re one of the best insects to have in your garden. They are one of the most effective insects for controlling plant-feeding insects who come to ruin the garden. They keep the pest level to a considerably low amount, helping growers save a considerable amount.

Not just that, but they’re also pollinators because of the way they go from bloom to bloom in a garden. They do not harm the vegetation growth during their travels, nor do they sit and feast on the plants.

Protecting yourself from fire ants is important, especially if you’re letting some take up residence in your garden. You will want to tuck your pants into your tall socks to reduce the chances of letting them get to your skin. Using a mosquito repellent with DEET in it is also helpful in addition to the coverage.

Africanized Honeybees

These bees have been seen across the news channels as insects you don’t necessarily want around. This is mostly because they’re termed ‘killer bees’ and are more commonly found in Africa. They are both good and bad, and here’s why.

These bees are still honeybees, so they pollinate, provide honey, and do the same things but they’re much more aggressive. They’re so much more aggressive than they’ve killed people. However, since they still pollinate and do the same things that honeybees do, they’re a great pest to have when pollinating and germinating a garden.

While they might be great at all of this, they’re still extremely dangerous. If you find Africanized Honeybees in your yard, you should always call an experienced terminator who can handle the situation. You do not want to get close to them, touch their hive, or try to handle the situation on your own as these bees are highly aggressive and extremely dangerous.

Wasps and Yellow Jackets

These scary creatures are actually beneficial to gardens in a number of ways. This means that those wasps that chase you often actually have a purpose.

Wasps and yellow jackets are beneficial because they feed their young wasps the insects that would otherwise eat the crops in your garden. This means, less damage is being done because there are fewer damaging bugs. They also feed on the house and blowfly larva. This will keep those other insects far away from the area.

Since wasps and yellow jackets are easily angered and aggressive, it is important that you stay safe when you’re around one of their nests. Always make sure to cover up and stay as far away from the nest as possible. Do not touch the nest. You should make sure the nest is at a safe distance away from the garden. This way, you can tend to the garden without fear of the yellow jackets, though they are considered pests.
