24 Home Remedies And Repellents To Get Rid Of Stink Bugs

Brown marmorated stink bugs, also known as Halyomorpha halys, or simply stink bugs are often seen in warm spring and summer periods of the year. They feed on fruits such as berries and peach. They are not harmful to humans but do ooze out a nasty smell when they are squeezed.

Here are some good practices, to consider, when dealing with stink bugs;

  • Keep your bushes and weeds well trimmed and maintained all year round.
  • Turn your exterior lights off at night.
  • As stink bugs like moist and humid places, do not allow moisture build up anywhere in your home. Fix clogged drainages as soon as possible.
  • Keep your home clean and tidy.

Below are 24 home remedies and natural ways to get rid of stink bugs;

1. Repair Cracks

The most effective way to get rid of stink bugs is blocking their entry into your house. Seal all the gaps around doors, window, lights and exhaust fans. If keeping doors and windows open is necessary, consider covering them with screens that check the entry of insects while allowing air and light to pass.

2. Sticky Traps

Sticky traps are excellent for catching flying insects around the home. The bright colored sticky strips of paper can be hung in the garden and entrances. You can easily get one at a pest control store near you. Just hang it in places where you notice stink bugs. They will get attracted to the bright color and will fly onto it. As a result, they get stuck and die.

3. Soapy Water

Soap and water is another great home remedy to kill the stink bugs. If you see a stink bug crawling on the window pane, wall or in your curtain, just prepare a soapy water by mixing some liquid soap to some water in a bucket. Place the bucket underneath the insect and knock it with the help of an object such as a broom or a stick. As soon as they fall over the soapy water, they get drowned and die.

4. Diatomaceous Earth

Diatomaceous earth is obtained from fossilized diatom and is non-toxic to humans. However, it acts as a potent pesticide killing insects and pests in a natural way. Sprinkle diatomaceous earth in the areas visited by the stink bugs. The white powder has a dehydrating action on them. As soon as they come in contact with it, their exoskeleton is damaged resulting in death.

5. Nicotine

Nicotine acts as a poison for the stink bugs and is a great home remedy to get rid of them. Just warm 1 gallon of water and empty a pack of cigarettes in it. Let it soak for some time until the water turns dark. Strain the liquid and, to it, add 2 tablespoons of liquid dish soap. Fill up a spray bottle with it and spray it directly on their body. The soap helps the solution to stick to their body for longer while the nicotine poisons them effectively.

6. Eradicate Their Eggs

One of the best ways to prevent a stink bug infestation is to get rid of their eggs. These bugs lay their eggs at a warm temperature usually around the spring. The eggs are present on green leaves of trees and plants. Look around your garden and find out their eggs. Trim your plants and discard the eggs carefully. You may also drown the eggs in a soapy water to kill them.

7. Neem Oil

Neem oil is a great insecticide and helps in killing many insects and pests. Mix neem oil with water and fill up a spray bottle with this solution. Use this spray to get rid of the stink bugs from your garden and home. Since neem oil does not cause any harm to plants, you may spray it in your garden to get rid of eggs and adult bugs.

8. Damp Towels

Stink bugs are attracted to damp fabric. Put a towel in water so that it completely soaks the water. Remove excess water from it and hang the towel outside your home preferably in the evening. All the stink bugs around your house would gradually fly onto it. Carefully, take the towel with the bugs attached to it in the next morning and dip it in soapy water. They will die due to drowning.

9. Garlic

Stink bugs detest the smell of garlic. As such, garlic repels them away from your house. Make a garlic solution using garlic powder and water. Put it in a spray bottle and spray the effective insect repellent in your garden, around your house, and near entrances. This would prevent stink bugs from entering your home.

10. Vacuum Cleaner

Vacuuming the bugs is an excellent way to get rid of them unless you have a problem with a smelly vacuum cleaner. To prevent the vacuum cleaner from smelling, however, try tying an old stocking in the mouth of the vacuum cleaner with the help of a rubber band. Now push the stocking inside. The bugs will get collected in stocking and you can remove it, seal it and throw it away in the trash.

Add rubbing alcohol and water to the ratio of 1:2 and put this solution in a spray bottle. Spritz it directly on their body to irritate them and they will leave your home immediately.

13. Use Wart Remover

Wart remover freezes the stink bugs in the same way as it freezes any warts. Spray it directly on their body. Once they get frozen, you can dispose them to get rid of the bugs.

Pyrethrum is toxic to the stink bugs and is effective in eliminating them from your garden. Take some dry pyrethrum flowers and crush them to obtain a powder. Mix this powder with water and a few drops of liquid dish soap. Spray it around the plants to protect them against the bugs.

15. Lemon And Vinegar

You can make an excellent bug repelling spray using lemon juice and vinegar. Just take a bowl and pour one ounce of lemon juice. Then add half an ounce of vinegar and mix well. Spray this mixture on the walls, access points, gaps and cracks to deter these pesky little insects.

16. Peppermint Oil

Stink bugs hate the smell of peppermint and get repelled by it. Add about 10-12 drops of peppermint oil in two cups of water. Pour it in an airtight spray bottle. Use this to spray on the affected areas every day until you see all of them moving out of your property.

17. Catch Them

If nothing else is available for you to repel them or kill them, you may try picking them up. This is only possible if the infestation is not severe. Just hold them lightly with a paper towel and flush them down your toilet. Avoid pressing them too hard as they will release their annoying smell that you are trying to avoid.

18. Use Hairspray

Hairspray tends to paralyze the stink bugs effectively. Spray it directly on their bodies and once they get disabled, you can pick them and put it in a plastic bag. Seal the bag and throw it in the trash.
