Diatomaceous earth (DE)

Diatomaceous earth is an effective powder that contains alumina, silica and iron oxide. The reason it is used in stink bugs is also the same reason it bears some efficacy in the treatment of bed bug infestations.

Choosing or selecting diatomaceous earth powder that has not been pre-heated is important as it is more effective than the otherwise.

In order to use this method, you will need to identify the spaces through which stink bugs enter your house then paste the powder along these areas such as the windows.

Peppermint Spray

Peppermint may be able to elicit its function on keeping stink bugs away from your house through the menthol constituent. Instead of the peppermint you can So as to make this home remedy;

  1. Get a cup of water with a dropper for the mint. However, you need to crash the leaves before you can use it. You can either use the distillation or solution method in order to extract the minty aromatic water that is beneficial in the repelling properties of the preparation. This is 250 mL and 10 drops respectively. Then shake to ensure that the mixture is uniform.
  2. Now spray the mint onto your plants in the garden not forgetting entry points of stink bugs such as windows and cracks on walls among other areas where the stink bugs hide.

Garlic spray

  2. Now spray the mint onto your plants in the garden not forgetting entry points of stink bugs such as windows and cracks on walls among other areas where the stink bugs hide.
  3. You should be able to do this daily until you have no pending sting bugs in your house. You should however note that garlic is a repellent and is not an insecticide.

Soap Water

  1. Make about 1L then measure out some liquid soap about 180 mLs.
  2. Add the water to the soap then use this mixture to spray where stink bugs aggregate. How soap water is deemed to work is through its ability to break down the protective exoskeleton through the action of the surfactant. Surfactants are wetting agents and are able to increase the wettability of the exoskeleton which absorbs water and makes it weak. Breaking of this layer leads to dehydration.

Physical Removal:

You can also opt of physical removal of stink bugs if they are not too many to do so. This method is best done in combination with other methods so that they both augment each other in doing an effective job. Some of the methods that you can use include:

Vacuuming stink bugs

  1. While using this method, target the areas that are most unreachable and where stink bugs hide. Especially the cracks and other holes that exist in your house. Well of course you wouldn’t use this method outside in your garden. One note is that you should choose to use a vacuum that has a bag as your vacuum is later going to stink if you do not do so.
  2. Once you have done the vacuuming, you should ensure that you empty the bag’s contents into a bin. Seal the bag properly to avoid emission of the foul smell.
  3. If you have a bagless vacuum, you can use a sock or any other clothing by pushing it into the mouth of the vacuum cleaner making sure that it is secure. So long as this is done, the stink bugs will be sucked up into the cloth.

Fly tapes are effective

Just as they work with other insects, this could work as well with stink bugs. Use this on the window frames, underneath your doors, cracks, crevices and other areas that you may deem ways they could get into your house. This method will only trap them and neither repel nor kill them.

Electrocute them

This method is applied on stink bugs in the night or by switching off the lights and switching on the electrocuting system.

The stink bugs will be attracted to the light. It is then electrocuted as it approaches the light.

Natural predator of stink bugs-What eats them?

According to the New Jersey Agricultural Experiment Station, in the United States, the brown marmorated stink bug isn’t native. It is purported that since they are not native, they have no natural enemies.

However, this may not be entirely true as there are insects that actually feed or prey on stink bugs.

Such insects include;

  1. Assassin bugs
  2. Predatory stink bugs
  3. Two egg parasitoid

These natural predators do not only prey on stink bugs but also a variety of insects out there. This means that even the beneficial insects in your garden will be fed on.

Some years ago, USDA research lab in Delaware, said that there is a much better and more selective predator that is being bred in the laboratory.

It is an egg parasitoid. It is a tiny wasp native to Asia that implants its own babies in the stink bug eggs, thereafter disallowing the growth and development of stink bug babies. There aren’t updates if this lab-made predator has been let out of the control room.

Killing Stink Bugs-Is it possible to Kill them yourself?

Harsh conditions kill stink bugs. This is why they hibernate away from cold weather and seasons. The adverse cold in the winter is not favorable for their survival and nor is it for the growth and development of the nymphs. They even choose to reproduce after the winter, in the early spring.

Your pet might also kill stink bugs. They do this out of shear curiosity in simple disgust. Remember that stink bugs are not aesthetic to look at even to your pet.

Shortage of food or famine will surely kill stink bugs though after a long time of hibernation during a time when they really tone down their metabolism in what is known as diapause.

How can you Catch and kill them yourself? Is it possible?

It is possible to kill the stink bugs yourself. The rule of thumb is that you ensure you do this outside and not inside the house for the malodorous smell might end up lingering for hours.

Squashing them with your finger could lead to an unprecedented hypersensitivity reaction. You would rather use your foot to do so.
