How To Kill Stinkbugs.
How to Kill a Stink Bug
Killing a stink bug can be a messy, unpleasant matter, since many methods will cause the bug to release an extremely pungent odor. Soapy water is one of the least messy and most effective methods to use, but other organic and chemical pesticides also exist. You can also exterminate the insects using more physical methods. Here's what you should know about killing stink bugs.
Using Soapy Water in a Jar
Fill a jar with water and dish detergent.Add enough liquid dish soap to the jar to cover the bottom. Fill half of the jar with warm water and stir to mix.
- Any liquid dish soap will work, regardless of how mild it is or what additional chemicals it may contain.
- The right size container will depend on how many stink bugs you intend to capture. A small custard cup or ramekin is enough if you only plan on killing a few of the pests, but a larger jar or small bucket should be used if you plan on taking care of a major infestation all at once.
Knock the stink bug into the jar.When you come across a stink bug, flick it off its post with a popsicle stick or chopstick and down into the soapy solution.
- Work quickly. Some species of stink bugs can fly and may escape if you do not manage to flick it off in one fell swoop.
- Stink bugs should drown within 20 to 40 seconds. The bugs breathe through pores beneath their waxy exterior shells, and when soap plugs these pores up, the bugs suffocate.
- You could also wear disposable gloves and pick up the stink bugs by hand. Similarly, you could pick them up with tweezers. Picking them up directly ensures that they will not be able to escape, but they may release their odor if you do not work quickly.
Flush the dead bugs.After you collect a few stink bugs in your soapy water, flush the contents of the jar down the toilet to dispose of the bugs and the dirty water.
- Wait until you collect a few stink bugs instead of flushing them individually in order to save water.
Using Soapy Water Spray
Fill a spray bottle with soapy water.Combine 32 oz (1 liter) of warm water with 3/4 cup (180 ml) liquid dish detergent.
- As before, any liquid dish detergent will work regardless of potency or added chemicals.
- Shake the bottle well to make sure that the soap and water are combined.
Spray the solution on bugs and along cracks.Douse any bugs you cannot knock down with the spray and apply the solution along any area you suspect the stink bugs might come in through.
- Even though this does not work as quickly as drowning the insects does, the soap with react with the waxy coating on the exterior of the stink bug, breaking that coating down and ultimately dehydrating the pest.
- Stink bugs usually sneak in through cracks, windows, doors, and vents. Spray a heavy coating of this solution around those areas so that invading stink bugs will walk through it and eventually die.
Using Traditional Pesticides
Be aware of the risks.While traditional insecticides may kill stink bugs, there are health risks and other potentially negative consequences involved.
- Insecticides are poisonous to humans and pets as well as stink bugs. Keep them out of reach of small children and pets, and strictly follow the application instructions on the label.
- Residual dust treatments can kill many stink bugs, but the bugs may die in hard-to-reach places as a result of the delayed effect. Carpet beetles and other pests may invade your home to feed on the dead bugs afterward.
- Aerosol foggers will kill stink bugs, but the effect only lasts for a limited amount of time, and any stink bugs that enter the area after the room is aired out will not be killed.
- Only use insecticides that are labeled to kill stink bugs. Otherwise, you run the risk of choosing a chemical that is not effective against these particular pests.
Spray the stink bug as you see it.Use a "kills on contact" aerosol insecticide to attack stink bugs as you see them.
- Understand that "on contact" is not necessarily as instantaneous as the term would imply. These chemicals usually begin to attack the stink bug's nervous system after they dry, but it could take several hours after initial contact before the bug dies.
Apply residual insecticides.Following label instructions, sprinkle or spray the product in any area you suspect the stink bugs to be hiding in.
- Residual sprays tend to work best when sprayed along window sills, doorways, and baseboards.
- Residual dusts tend to work better when dusting the attic, crawl spaces, or interior wall space.
Use a perimeter insecticide outdoors.Spray an outdoor residual pesticide along the ground around your home's foundation.
- Stink bugs always invade from the outdoors, so any stink bug entering your home for the first time will be affected and killed.
Use a nicotine solution.Soak a pack of shredded cigarettes in 1 gallon (4 liters) of warm water. Strain the solution and mix in 2 Tbsp (30 ml) of dish detergent.
- Fill a spray bottle with this solution and thoroughly coat the stink bug with it.
- The liquid dish detergent allows the solution to stick to the insect more effectively, and the nicotine poisons the stink bug.
- Wear disposable gloves as you work with the nicotine solution to avoid accidentally absorbing the poison through your skin.
Using Household Solutions
Paralyze stink bugs with hairspray.Attack each stink bug with hairspray as you see it to stop the pest from moving around.
- The hairspray alone will not kill the stink bug, but it will immobilize it, preventing the bug from roaming about freely and making it easier to apply a chemical that will kill the bug.
- Make sure to use the stickiest hairspray possible. Thankfully, cheap brands are usually stickier than expensive brands.
Kill the bugs with rubbing alcohol, bleach, or ammonia.Fill a glass jar halfway with one of these chemicals and knock or drop the stink bugs into the jar as you come across them.
- Do not mix these chemicals for any reason. Combining these chemicals can produce fumes that are deadly to humans.
- Knock the stink bugs into the solution using a popsicle stick or gloved hand, or pick the bugs up with tweezers.
- You could also dilute one part rubbing alcohol with three parts water inside a spray bottle. Attack stink bugs with this solution as you see them. The alcohol will wear away at the exterior of the insect, drying it out and eventually destroying it.
Kill the bug with wart remover.Buy a can of freeze away wart remover and spray it directly on the stink bug. The bug will freeze instantly and all you need to do is flush them down the toilet.
Spray the stink bug with hot sauce.Fill a spray bottle with hot sauce or liquified hot peppers. Squirt each stink bug with the spicy insecticide as you see it.
- Hot peppers are capable of burning human skin and eyes if handled improperly. Similarly, the peppers can burn away the waxy exterior of the stink bug, ultimately destroying it.
- Wash your hands after handling hot peppers and hot sauce to avoid accidentally irritating your eyes.
Drop candle wax remover on the stink bug.Place a single drop of candle wax remover on the back of an individual stink bug. The insect should die within one or two minutes.
- You might be able to apply the candle wax remover to the stink bug without capturing it, but be aware that accidentally getting the remover onto carpet or other surfaces may create a stain. For best results, immobilize the insect with hair spray or trap it inside a glass jar before applying the remover.
- The candle wax remover strips away the waxy coating on the outside of the stink bug's shell, thereby breaking down interior membranes.
Use white vinegar.Place a tablespoonful / teaspoonful of white vinegar in a container; use a container that is not too large.
- Capture the stink bug using tweezers, an empty medicine container with cap, and/or use gloves.
- Put the bug or bugs into the vinegar. They die immediately without releasing their bomb.
- Flush the critters down the toilet.
Using Physical Extermination
Vacuum the stink bug up.When you see one or more stink bugs, suck them up using an upright vacuum with a bag.
- The stink bugs will release their odor inside the vacuum, causing the machine to stink for several weeks. Sprinkle the interior of the vacuum with a strong deodorizer to minimize this effect.
- Avoid using bagless vacuum cleaners. Use vacuums with bags and dispose of the bag after you finish sucking up the bugs.
- Alternatively, wrap a knee-high stocking around the outside of the vacuum tube and secure it in place with a rubber band. Stuff the rest of the stocking into the tube and suck the stink bugs up as usual. This will prevent the bugs from passing through the vacuum filter.
Set up an insect electrocution system.Place a bug zapper in a dark attic or closet.
- Like most insects, stink bugs are drawn to sources of light. By placing the device in a dark room, the light of the electrocution system becomes more appealing to the stink bugs. As they approach the light, they are instantly electrocuted and die before they have the chance to release their stink.
- Make sure that you sweep up or vacuum up the dead stink bugs after several days pass.
Lay out glue traps.Spread flypaper or other sticky traps near windows, doorways, vents, and cracks.
- The stink bugs will get caught on the traps as they pass over them. Without being able to search out food, the insects will starve to death.
- Throw out the glue trap after you have gathered several stink bugs.
- Be aware of the fact that stink bugs may release their odor upon becoming stuck to the trap.
Freeze the insects to death.Trap the stink bugs in a resealable plastic freezer bag or airtight, freezer-safe container. Place the container in a freezer for several days to kill them.
- Make sure that the container or bag has a tight seal. Otherwise, you run the risk of contaminating the contents of your freezer.
Put a glass over the bug and leave it till it kills itself on its own toxic emissions.Quickly pick up the glass. Sweep the dead bug into the garbage.
- Make sure you do this outside because the chemical will build up and you can actually see the brown fumes.
QuestionIs there any way to bait them? I was hoping to attract them to something so I could kill them en masse.wikiHow ContributorCommunity AnswerStink bugs like sweet stuff. Leave candy out, and it will attract them. You can attach the candy to the sticky trap.Thanks!
QuestionDo the stink bugs in North America carry/transmit diseases? I read that a species in Central/South America carry a parasite that can kill you by causing fatal heart damage.Kelly B WillyCommunity AnswerThe Brown Marmorated Stink Bugs (their technical name) are pests, but not deadly pests. Some experts even go so far as to say that they are more dangerous to orchards than they are to humans, and that we get rid of them just because we don't want insects in or around our homes. Essentially, unless you are a tree, they are harmless. As of right now, they are not considered to be carriers of parasites.Thanks!
QuestionOther than hitting them with a fly swatter, how do I keep them away?wikiHow ContributorCommunity AnswerTry using soap solution to kill off any of these pests who try to break in.Thanks!
QuestionWhat if my dog eats one? He kept rubbing his mouth on the carpet and then vomited--is it poisonous?wikiHow ContributorCommunity AnswerStink bugs aren't poisonous, but their secretions can irritate an animal's gastrointestinal tract, causing them to vomit or drool excessively. It is not fatal and the upset will pass on its own.Thanks!
QuestionI find small stink bugs on my bed. How can I find out where they're coming from?Kelly B WillyCommunity AnswerFigure out where there are cracks that access the outside. Is there a window in your room? Check its frame for even the most microscopic of holes. Is there any other window in your house that may have cracks, or another small opening to the outside? Also, do you have any window or wall air conditioning units? They can come in through or around a/c units. Do you have a screen door? I just found some hiding in the recesses of my screen door. Lastly, how solid is your foundation or basement? That's another entry point. ANY tiny opening!Thanks!
QuestionWhat do I do if the stink bug doesn't go into the soap?Kelly B WillyCommunity AnswerThey tend to be pretty dumb. As long as you don't touch them, they usually stay where they are, and they don't scare when you attempt to get them. So you will have ample chances to try again.Thanks!
QuestionIf I kill a stink bug in my house, will that bring in more of them?wikiHow ContributorCommunity AnswerIf you squish them, they will release an odor that will attract more. But you can kill it using a spray or trap without squishing them, which will not attract others.Thanks!
QuestionCan I drown them in the toilet without using a soap solution?wikiHow ContributorCommunity AnswerWhat I've been doing is picking them up with toilet paper or a paper towel, then dropping them into the toilet. Letting them sit in the toilet bowl for a minute or two will ensure that they drown. Wrapping them in toilet paper or a paper towel will ensure that they are completely submerged.Thanks!
QuestionCan a battery-operated fly swatter kill a stink bug?wikiHow ContributorCommunity AnswerAny kind of fly swatter can kill a stink bug, but keep in mind that squashing the bug will release a stinky odor, hence the name, "stink bug". The smell will then attract other stink bugs, but if you clean and deodorize the area quickly, it shouldn't be a huge problem. Better to relocate the bug while alive to avoid this problem.Thanks!
QuestionWhat kind of vegetation and trees are they attracted to? How about a mulberry tree?Kelly B WillyCommunity AnswerAs far as I've researched, they aren't picky. They are known to ruin orchards, as well as houseplants and cardboard - they eat lots of stuff. I'm not sure if there's anything they won't eat. I have pine trees in my yard, and they hang out in them, too. You may want to hire an exterminator to check your tree.Thanks!
- Seal up your house to prevent more stink bugs from coming in. No extermination method will kill future infestations of stink bugs. The only way to be rid of them long-term is to seal off vents, cracks, and holes leading from the outside in to prevent more from coming back in.
- Do not squish a stink bug. Doing so will cause the stink bug to release its powerful odor.
- Wear glasses or protective goggles to protect your eyes in case the bug sprays. This burns and can be very painful. Flush eyes immediately with copious amounts of water and administer eyewash and drops. See your doctor if pain/discomfort persists.
