Stink bugs are large bugs which possess glands to produce odor as a defense against their enemies. Most stink bug species feed on plants and therefore, might be a serious crop pest. This bug also attacks fruits, causing major damages to these fruits. A few species of stink bugs, on the other hand, feed on other insects, such as aphids and beetles. Hence, they might become a beneficial protector for crops against destructive pests. Moving from the garden and lawn, these stink bugs can possibly be an indoor pest, when they start to infest some indoor areas as a barrier against cold. Commonly, indoor stink bug infestation can be seen on the wall crevices and cracks, as well as window sills. Large infestation might cause damages to indoor objects as well as garden plants. Hence, thorough extermination is essential.
How to kill stink bugs
To exterminate the entire population, killing the stink bugs is one of the most effective methods. There are various methods which may put them to death, and these methods might involve physical extermination, chemical extermination, and folk remedy extermination.
The main problem with killing stink bugs is that this insect may release their odor once squashed or even only disturbed. In fact, the odor glands work when the tiny bugs are threatened. Hence, killing the bugs immediately will be the best solution. To do instant physical extermination, you might want to consider these methods:
Vacuuming is a good method for extinguishing various kinds of tiny insects, including stink bugs. While merely vacuuming might not kill the bugs, sprinkling some powdered diatomaceous earth into the vacuum bag before using it to suck the victims adds the possibility of killing the sucked up bugs once they are trapped in the bag. To kill stink bugs by vacuuming, here are some directions:
-Use bagged vacuum cleaner so that you can dispose the bag and trapped bugs thoroughly after treatment.
-Stink bugs are going to release the odor inside the vacuum cleaner since they are threatened. To eliminate the odor, put some deodorizer in the interior for some consecutive days.
Zapping is also an effective method of exterminating stink bug infestation, especially the indoor one. To do this, use zapping instruments used for flies or other small insects. The light will draw the bugs into the instrument, which will kill them by electrocuting. Consider these things when trying to electrocute stink bugs:
-Put the zapper in dark room to ensure the light exposed by the device is appealing for stink bugs.
-This method is beneficial in killing stink bugs in cramps places, such as the attic, wardrobe, or cabinets.
-Zapper kills stink bugs quickly before they are able to release the defense odor.
Trapping might be effective for slightly larger infestation, although this method does not kill stink bugs as fast as vacuuming or zapping does. Hence, the bugs can still possibly release their odor after trapped. Stink bugs trapping can be done with these steps:
- Use glue traps for killing stink bugs. You can either use glue traps for ants or cockroaches.
- Put these traps in susceptible places or where stink bugs are seen foraging. These traps can also be placed in the garden or hung on tree branches.
- Trapped stink bugs will not be able to feed so that they will eventually die of starving.
- Dispose traps full of bugs and replace if you still see some others.
Killing stink bugs can also be done by freezing the bugs. It seems quite strange to put infested goods or objects in the freezer to freeze. However, liquid nitrogen can be used for this purpose. There are kinds of liquid nitrogen which are sold for the kitchen. Spray the stink bugs with it to freeze and finally kill them. This method will be effective for both indoor and outdoor infestation. If you cannot find any liquid nitrogen, use hairsprays to perform the method. Directly spray it onto stink bugs to paralyze and eventually kill them.
Insecticides should be the last resort to kill stink bugs. These chemical-based substances can be used indoor and outdoor, as long as you make sure to avoid its residue as much as possible. If you are having stink bug infestation in small crawling spaces, such as window sills, baseboards, or doorways, spraying insecticides may be helpful.
If you prefer some stink bugs traps which you can make yourself, you might want to try making the simple natural trap for killing stink bugs.
Stink bug trap
This trap is useful for catching stink bugs which infest indoor area of the house. The trap is affordable, eco-friendly, yet effective in capturing the little invaders. To make the trap, you will need:
- Two-liter clear bottle
- Black electrical tape
- Masking tape
- Utility cutter
- Stick-on LED light
Required steps for making this trap are as follow:
- Cut the bottle into two pieces and cover 1/3 part of its bottom with black electrical tape.
- Insert the battery-operated LED lamp into the middle of the bottom part.
- Put the upper part of the bottle and position it upside down to the bottom part.
- Gather the two parts using masking tape which later will function as the ladders for the stink bugs to “climb up” the trap.
- Put the trap in dark places and turn the LED lamp using pen or chopstick. The light will function as stink bug attractant, which encourages the bugs to climb up the bottle and fall into the bottom part.
- When the trap is full of stink bugs, remove the masking tape and dispose of the bugs.
- To reinstall the trap, reattach new masking tape and set the trap up.
Some people might think that making a stink bug trap is quite complicated and thus, prefer to get rid of these bugs invading the house by using some natural repellents. In fact, this method can be great, since there are some ingredients you may find around the house, which is effective to work as stink bug repellants. Read on to find out some of those.
Stink bug repellants
Garlic has a strong aroma and high acidity. These will keep small insects, including stink bugs at the bay. Sprays made from garlic is thus effective for deterring stink bugs indoor and around the garden and lawn. Repel these bugs by making a mixture consists of 3 crushed garlic (can be replaced with 4 tablespoon garlic powder), and 300 mL water in a spray bottle. Spray it directly onto susceptible spots, or places which are infested by the bugs to repel them.
Mint is also a remedy for deterring bugs since it produces smell which is very unattractive for them. To make the mixture, you will need 300 mL water mixed with either 10 drops of mint essential oil or a handful of ground mint leaves. Mix the ingredients in the bottle and shake. Spray directly onto targeted spots and plants to protect.
In the garden, catnip will be loved by your kitchen, but not stinky bugs. Hence, planting catnip in the lawn or pots will make it easier to get rid of foraging stinky bugs. Catnips have a very strong smell which disturbs stinky bugs’ sense of smell. If you are expecting an easier and simpler catnip remedy, buy powdered catnip from the grocery store and sprinkle it around the garden and other areas indoor which are susceptible to stink bugs.
Some drops of essential oils are effective in deterring stinky bugs—even some other kinds of bugs. Dilute some drops of any essential oils of your preference and spray it to the areas when stinky bugs are seen. For indoor prevention, burn some drops of essential oil in the diffuser might discourage stinky bugs and hence, keep them outside.
What kills stink bugs?
Sometimes, especially when the infestation is severe, it is not enough only to deter foraging bugs. Instead, you will need some remedies which are able to kill the bugs immediately. Moreover, stink bugs excrete unpleasant smell when disturbed, so that killing might be a better option. Read on to know what remedies which kill stink bugs effectively.
Diatomaceous earth is not the only natural but also very effective for killing stink bugs. Apply by sprinkling it onto the soil where stink bugs are often spotted. DE is not harmful to plants so that it is also directly applicable to plantation and flowers in the garden. The food-grade DE also does not harm any pets, so that it is safe for indoor use.
A mixture of 300 mL water and 2 tablespoons mild dish soap creates a lethal repellant for stink bugs, yet safe for humans and pets. Spray the mixture directly to areas, crevices, or plants where stink bugs commonly gather. This mixture will repel them and eventually kill them by dehydrating the bugs.
If you are a heavy smoker, you might be able to put the cigarettes into a healthier act. Nicotine which is contained by cigarettes is effective in killing stink bugs. To do this, put 2 liters of warm water in a container and put shredded cigarettes in it. Stir it until the water becomes black. Add few drops of liquid dish soap and strain the solution. Put the mixture into a spray bottle and spray directly to any stink bugs you see to kill them.
Alcohol kills stink bugs by dehydrating them. To do this, fill a jar with rubbing alcohol and drop caught stink bugs into the solution. Be careful not to squash them while catching as they might attack you with the stinky odor.
Hot peppers or cayenne pepper is a remedy which works best for small bugs. This substance kills the bugs by burning its exterior, leaving them dead. To make the natural yet effective mixture, dilute 2 tablespoons of hot pepper into the water in a spray bottle and shake it. Spray the solution directly onto seen bugs to kill them eventually. Be careful not to spray the mixture in a too close distance, as it might burn your eyes.
Stink bug control
Among all the stink bug repellents and killers, there is none which is going to work permanently and effectively when dealing with a large infestation. Instead, preventing the bugs from infesting the house at all might be the best solution. There are some methods and remedies which are actually effective in keeping stink bugs away from the house and garden. Learn these methods to protect the house and leave it bug-free.
- Seal all entry points, such as wall cracks and crevices.
- Patch up holes in the walls or wooden foundation at home, as it might be the place used by stink bugs to lay their eggs. Use instant adhesive or epoxy to patch even small holes you spot.
- Keep all bushes and weeds in the garden trimmed. Put away all decayed organic matters laying in moist soil, which is susceptible to bug infestation.
- Switch off all the lights, especially in susceptible places, such as the garden and lawn, and also the inhabitable places, such as the attic, as most bugs—stink bugs included, are attracted to lights. If you insist on turning the light on, replace the bulb with LEDs of yellow bug bulb to minimize bugs gathering around these sources of light.
- Keep the house clean and dry. Use a dehumidifier to control the level of humidity indoor. Clean unused spaces such as the attic and basement regularly to prevent bug infestation without being noticed.
- If you notice bugs entering your house, catch them with a paper tissue and relocate them by flushing to the drain or simply throw them outside to freeze in the winter.
- Sprinkle diatomaceous earth—ground egg shells for kitchen scraps will also work great—in a regular basis to prevent your garden from being infesting by stinky bugs. DE will not harm the plantation so that you are allowed to sprinkle it generously.
If you have a large stink bug infestation outside, soak a towel in the water and squeeze it. Hang this damp towel outside overnight to attract any residing stink bugs. The towel moisture will attract the bugs, which are going to attach themselves to the towel. In the morning, you will see a lot of bugs hanging on this towel, which you can directly exterminate by soaking them in soapy water.
