Here are some effective homemade killer sprays for bees and wasps.

Both wasps and bees can pack a hard sting, and I don’t assume anyone would want to be on the receiving end of such a sting.

Depending on the bee or wasp species, these stings can cause severe pain and sores on your skin.

Natural Killer Sprays For Bees And Wasps

Sadly, these insects can make their way into your home or garden and keep you uncomfortable.

Not to worry, there are several remedies you can try on bees and wasps.

About Wasps

If you leave a wasp alone, it will reciprocate by leaving you alone. On the other hand, if you bother a wasp, it will attack and sting you.

With this knowledge in mind, you don’t always have to approach a wasp nest, especially if it is far away from your house. You can let them be.

However, like most other insects, wasps do not like freezing temperatures. This causes them to freeze and die. For this reason, wasps may start to approach your home in search of warmth during the winter season.

About Bees

Bees are very vital to the ecosystem, and for good reasons too. They are pollinators that are partly responsible for plants to thrive.

In fact, according to the NRDC (Natural Resources Defense Council), 30% of the crops in the world and 90% of the wild plants thrive because of cross-pollination.

Many plants, including food-bearing trees, would be dead and gone if not for the activities of bees.

Having this in mind, killing these beneficial creatures would be a terrible idea. They indeed deliver powerful stings that hurt and can make their way into your home searching for sweet foods, but repelling them would be the better, eco-friendly option.

Homemade Wasp Killer Spray

These sprays are made from purely organic substances, and they pose no threat to human or plant life. They are also straightforward to prepare, and about anyone can do them.

Try these combinations –

Liquid Soap And Water

As simple as this combination may seem, it does very well to kill and repel wasps in your home or your garden.

Keep in mind you are not to use just any type of soap. The degreasing versions are your best bet at getting the wasps killed. The good thing about this combination is that it also works well on other pest insects like roaches and ants.

You need a few tablespoons of degreasing liquid soap, a container, some water, and a spray bottle.

Add about four teaspoons of decreasing liquid soap to the water-filled container, then stir it thoroughly until it produces foam. The next step would be to pour the mixture into a spray bottle and seal the lid tightly.

All that’s now left is to visit the wasp nest and spray directly at them. If you come across one or two of them around the home, you can spray directly on them.

I have to warn you that wasps can be very aggressive when an intruder approaches their nest. They will become more aggressive when they find their nest is under attack.

For this reason, be sure you are putting on the type of clothing that will keep you 100% safe from the stings of the retaliating wasps.

Such clothing should include a long-sleeved shirt or sweatshirt (preferably a turtle-neck type), hand gloves, trousers, boots, stockings, and a net hat to prevent the wasp from stinging your face.

Garlic & Cayenne Pepper

Garlic has proven to be one of Earth’s most potent food producers. It has too many health benefits for humans and can be used to treat high blood pressure, remove toxins from the body, and improve eyesight, to name a few.

But as beneficial as it is to humans, it wreaks havoc on many insects, wasps inclusive. This is because garlic contains sulfur, which most insects find irritating. They cannot stand the powerful scent and harsh effects of sulfur.

Cayenne pepper is another strong spice that irritates pest insects—pepper in general packs a punch that even humans cannot resist if enough amounts are consumed.

A mixture of garlic and cayenne pepper into a liquid spray can spell doom for wasps, and preparing the solution is very simple.

All you need is a few cloves of garlic and a handful of cayenne pepper. You will also need a container to prepare the mixture and a spray bottle to serve as the assault weapon.

Get a few cloves of garlic and grind using a blender. You can do more than one round of grinding to ensure the garlic cloves have been crushed to a powdery or dusty form.

Do the same to the cayenne pepper. Throw some into the blender and grind thoroughly until it is fine and ready to be mixed.

Pour the ground pepper and garlic into a container and add some water. Mix it all up properly until they are well blended. The next step would be to fill the spray bottle with the garlic/cayenne pepper solution and visit the wasps.

Spray across the nest or other areas around your home where they usually frequent. You can also spray directly on them as you spot them.

Make sure you’re prepared for a fight. Wasps will not sit back and take a beating. They will attack you if you come too close to their nest. Although there won’t be much, they can do when they start getting hit by the garlic/cayenne pepper spray.

Nonetheless, put on some protective clothing before you approach a wasp nest. Ensure your face, body, hands, and feet are well covered so the wasp stings won’t get to you.

One of the reasons why many people use garlic to fight against insect pests is that it also acts as a repellent. If you spray your garden plants and areas where the wasps may be active regularly with a homemade garlic spray, the wasps will lose interest in visiting those areas.

You can add peppermint oil to the garlic/cayenne pepper spray to improve the spray’s repelling abilities.

Natural Bee Repellent Spray

There are several homemade killer sprays for bees you can prepare, but you are advised against them. This is because bees are a big part of the ecosystem, and without them, the earth would have a severe vegetation problem.

If bees are bothering you around your home, the safest thing to do is repel and not kill them.

Luckily, there are homemade repellent sprays you can make that will chase the bees away but won’t kill them.

You can use this repellent indoors and outdoors as it is safe for both humans and garden plants.

Follow the tips below to make a homemade bee repellent spray.

How To Prepare

Get these materials first –

  • Cayenne pepper
  • Cinnamon
  • Peppermint oil
  • A spray bottle
  • Castile liquid soap
  • Water

The smell of peppermint oil and cinnamon is something bees, and wasps hate. They can’t stand it and will do all they can to escape it. Using these two materials, making a bee repellent spray will work well to keep them away.

Here’s what you need to do.

Add some cinnamon and a few drops of peppermint oil into a container, then stir. Grind up some cayenne pepper using a blender and add to the mixture.

Cayenne pepper is also another natural product that irritates insects, including bees. This is because it has a long-lasting burning that is harmful to insect pests.

Castile liquid soap is the last piece of the puzzle. Add some teaspoons of it into the container and mix it up thoroughly. When the mixture is blended correctly, please take it to the areas you want the bees to stay away from and apply.

It would be best to concentrate on areas where the bees are most likely to use to gain access into your homes, such as the doors and windows.

You can also spray around your patio deck and front porch. Apply some sprays on and under your garden benches to keep the bees away.

After the spraying has been done, the water will evaporate, but the other repelling elements such as the cinnamon and peppermint oil will still be there. These will keep the bees from buzzing around.

For outdoor spraying, the water level in the mixture shouldn’t be too much, just so the other repelling elements will be more pronounced.


You can prepare a homemade killer spray for bees and wasps all by yourself, although it is ill-advised to kill bees since they are very beneficial to the ecosystem.

I trust this piece has been helpful.

Take care.
