Not all insects are essential for the ecosystem. And, in the case of stink bugs, a severe infestation is certainly not something you or anyone else needs. By using one of the best stink bug killer sprays, you can save yourself the wait associated with using traps.

And, it will also make the disposal of dead insects a bit more convenient.

Check out the best sprays you can get, whether you want something fast and toxic or just reliable and environmentally-friendly.

Best Stink Bug Killer Sprays for Home Use

Available in one-gallon canisters, the Harris Stink Bug Killer is one of the fastest-acting solutions to dealing with stink bugs. The formula contains Deltamethrin as the main ingredient, which makes it quite toxic.

The good news is that it’s both odorless and non-staining so you can spray it inside and outside your home on any surface. While it doesn’t kill on contact, it does dispose of the pests relatively quickly.

Using this bug killer is very easy. While the canister may be bulky, it does have a convenient handle as well as a trigger sprayer. The sprayer has a medium width dispersal pattern, so it’s suitable for both spot and broadcasting applications.

It is also a suitable choice if you’re shopping on a tight budget. Just keep in mind that you need to seal off treated areas from small pets after spraying.

  • Odorless
  • Extension sprayer
  • Dries fast
  • Non-staining
  • Not the best residual control effect

The Ortho Home Defense Insect Killer is there for indoor and outdoor use. The formula is quite potent, and besides killing stink bugs, it can also repel them.

Getting rid of stink bugs may not be as difficult as you think. But, with this Ortho formula, you can go one step further. Because it contains an insect growth regulator, it will remain active for a long time.

It can provide residual control for up to a year. On top of that, like many other pesticides today, it won’t stain sprayed surfaces, and it doesn’t have a potent odor. That doesn’t mean that you shouldn’t still seal any treated rooms for a while and open the windows.

Since it’s not a natural product, it can still be toxic to humans and pets, especially those of the smaller variety.

The sprayer has a broad dispersal pattern, so treating large areas fast shouldn’t be an issue.

  • 12 months of residual control
  • Odorless
  • Wide dispersal pattern
  • Works as a repellent too
  • Not the fastest-acting formula

If you’re having a hard time getting rid of stink bugs with conventional insecticides, then maybe you need something more potent. The FMC Talstar is a professional-grade insecticide that obliterates stink bugs, ants, roaches, and even spiders.

I would recommend it for outdoor use. And, you should handle it with care and keep away from pets. The formula uses Bifenthrin as its main ingredient. It’s a potent pyrethroid that quickly targets the nervous system of insects.

But, it can affect aquatic organisms too. So, you might want to keep it away from your Koi pond for starters. That said, while it is more toxic than others, it also has tons of benefits. For one, it disposes of pests very fast.

Secondly, it offers long-term residual control, which is always great if you want to prevent a reinfestation. The fact that it comes in gallon containers and that it acts as a broad-spectrum insecticide are neat perks too.

  • Very potent
  • For broad-spectrum applications
  • Great residual control
  • Non-staining
  • Expensive

You can use the Buggslayer Insecticide just about anywhere. Whether outdoors on the patio or inside your home directly on carpeting and upholstery, you won’t have to worry about stains.

It has a unique Deltamethrin-based formula, designed not to leave any marks once dry. It is also odorless. Although effective against stink bugs, this insecticide has other applications too. You can also use it to target dust mites, bed bugs, ants, and other annoying pests.

It also has some residual control effect, seeing as stink bug carcasses can still broadcast the poison to other bugs that go near them or eat them.

That’s a good thing since it can take up to one hour for bugs to die after coming in contact with the substance. I consider this an average killing window. Therefore, it may be difficult for some pests to make it back to the nest and broadcast the poison.

You can also use this to prevent infestation, not just treat it. Do this by spraying a barrier around entry points in your home, such as doors, windows, etc.

  • Non-staining
  • Fast-drying formula
  • Effective residual control
  • Ready-to-use spray
  • Not everyone wants delayed results

MDX Concepts is perhaps best-known for its development of numerous natural alternatives to synthetic insecticides. The Magma Home Pest Spray is a good example, and it has a very potent formula too.

It can kill stink bugs quite fast. And, while it may not be as odorless as other products, the fact that it’s harmless to pets should compensate for that. Besides, unless you have a problem with peppermint, the scent shouldn’t be an issue.

The formula dries quickly, doesn’t create fumes. It won’t damage upholstery, wood, or any other material you spray. That includes plants too.

If there’s one downside to it, it is the fact that it doesn’t offer much in terms of residual control effect. It can exterminate stink bugs, but it’s not great at keeping them away.

  • Natural ingredients
  • Pleasant minty scent
  • Pet-friendly
  • Fast stink bug killer
  • Little to no residual control

Although Harris already offers a stink bug targeted insecticide, you could also try a more broad-spectrum formula if you’re dealing with more than one species of pests. And, this formula is also eco-friendly so you can use it at any time, anywhere.

The two main active ingredients are cottonseed oil and clove oil. Both are safe to use around pets and young kids. The formula doesn’t stain. And, even though it features essential oils, it’s still considered water-based and won’t leave a sticky residue.

The Harris Home Pest Spray comes in gallon containers. But don’t worry, as they have extension sprayers. That means that you can treat large areas fast and efficiently.

What’s surprising is how resilient the formula is when used outdoors. Although it may dry faster, it should still offer some lingering residual control and act as a barrier around your home. It may not be the most effective way of preventing a reinfestation, but seeing as it’s a natural substance, you can use it repeatedly even on your lawn and plants.

  • Pet-friendly
  • Can be sprayed on plants
  • Non-staining and no residue
  • Natural ingredients
  • Inconsistent spray handle quality

What Are Stink Bugs?

Known for their predominant brown features and the foul odor they release when crushed, stink bugs are an invasive species. They typically go about their activities outside, but they can also find their way inside your home and eventually nest there.

It’s also a type of bug that can get very large, growing in size each time they shed their skin.

Best Course of Action

Usually, the quickest way to deal with stink bugs is to use a spray-type insecticide. Whether you’ll go with one that kills on contact or one that acts as a broadcasting poison, it’s up to you.

It’s important to understand that just using repellents may not be enough to deal with a severe infestation. Just like traps aren’t always good enough if you want to get the job done fast.

When to Spray

You can spray at any time of day or night. Unlike when targeting bees or other aggressive pests, there’s no such thing as spraying too early or too late for stink bugs.

What’s most important is to figure out where they like to swarm. Find the most beaten path and always spray in high-traffic areas. Of course, spraying bugs directly when you see them will yield the fastest results.

Natural Insecticides vs Synthetic Insecticides

As is the case with other pests, you can always choose between powerful, albeit toxic insecticides and less potent natural alternatives.

The main difference is usually how long the application lasts. Synthetic insecticides will sometimes feature very potent chemicals or even insect growth regulators. That means that it should be easier to prevent reinfestation with such products.

On the other hand, natural insecticides, like those derived from plants, can kill bugs fast too. But, the residual control may be minimal at best. Depending on the specific formulation, sometimes the best you could hope for is a repellent effect. Unfortunately, it won’t always be guaranteed to work.

The upside is that you can spray natural insecticides as often as you like. And, it won’t matter if you spray them on plants, upholstery, furniture, or anything else.

Stop Stepping and Start Spraying

Stink bugs don’t cause too much damage. But, once you start stepping on them one by one to get rid of them, the odor they release might be unbearable for you and your family.

Finding the right stink bug killer shouldn’t be a problem with this article. Stink bug sprays are easy to use and usually a cheaper alternative to traps too.
