The number of bed bugs have been steadily increasing over the last 50 years and are almost at epidemic levels (crazy!).

Few people know about them or what to do when you find them.

This article gives you some tips and suggestions on what bed bugs are and some of the best bed bug sprays available to combat them.

What Are Bed Bugs?

A bed bug goes through different life stages after hatching until becoming a fully grown adult. The young ones can be as small as a speck of dust and the white eggs can fit on a pin head. As they mature, they grow to about 5 mm in length and are the size of an apple seed.

Adults turn red after they bite and inject an anticoagulant to stop the wound from healing, which is often the cause of the itchiness. The pests are nocturnal and you will only ever encounter them and get bitten late at night.

The scary part is that some may not ever be aware that they have bed bugs. And, it takes months before you start to notice them.

And when you do notice them... you're already in trouble.

Take a quick look at the video so that you have a really good understanding of what bed bugs look like.

How Do I know If I have Bed Bugs?

Most people begin to realize that they have a problem when they start to see bites that are very itchy. Other characteristic signs include seeing black fecal matter on the corners of the bed sheets or mattress.

It’s not uncommon to see a red stain on your bed after you have crushed the ones that have recently fed. You can sometimes see the empty exoskeleton as they mature and shed their skins.

A lot of people panic when they find they have bed bugs and decide to leave their bed and sleep in a spare room. Some even go as far as staying with a friend. These are the worst things that you can do. Bed bugs are hitchhikers and will use you as a carrier to move to different parts of your houses or elsewhere.

The best thing is to stay calm and try to protect yourself from bites whilst simultaneously calling an exterminator.

Bed Bug Warning

If you do think you have bed bugs, we highly recommend first consulting with a local exterminator before using sprays or any other method of bed bug control. Improper use can and will make your bed bug problem worse.

What Are Bed Bug Sprays?

Bed bug spray is an insecticide based spray that works great for bed bugs that you can see and spray directly, but has no effect on the majority that you can’t.

Most of the sprays will kill bed bugs that come into direct contact within a few minutes. 

Some sprays have a residual effect for up to 48 hours, which is great but can be hit or miss. Just because you spray an area, doesn't mean it's going to kill bed bugs.

Sprays are effective if you’re strategic and use it regularly over a period of time. Use it in the places where they’re residing, such as in a suitcase or the corners of a mattress.

How Do Bed Bug Sprays Work?

The best bed bug sprays use a chemical insecticides.

The EPA describes in this article the various kinds of chemicals that exist and how they kill bed bugs. Pyrethroid is a common ingredient in some sprays.

You also need to take care when you’re using it indoors since they can leave a bad odor and chemical residue on your clothes. This can be bad if you have children or pets.

Are Sprays Effective?

Like everything else... it depends.​

Some bed bug sprays use outdated insecticides that bed bugs have grown resistant too.

The vast majority of bed bugs hide deep in the crevices your mattress or room and sprays won’t reach them. This means that even the best bed bug sprays are only useful in a minor sense.

You should do a thorough search of the house and identify the places where they are. Use a generous amount of spray regularly over a period of time. Yet, this is best used after consulting an exterminator to prevent the infestation from spreading.

Pro Tip About Bed Bugs

Due to the seriousness of a bed bug infestation, we at Pest Strategies highly recommend contacting an exterminator before doing any self treatment, which includes sprays.

By using bed bug sprays,  you may end up making your bed bug problem worse by spreading bed bugs into new parts of your house.

For example, if you spray a location where bed bugs are infested, you might kill some some, but the remaining ones will probably find a new hiding place.

Bed Bug Spray Products Reviewed

As a recap, here are the 5 sprays we looked at. Our #1 pick went to Bedlam, but check the others out to see if they are more suited to your needs. 

Of course, always be careful when handling chemicals (non-toxic or not).

  • Top rated and well respected in pest control communities
  • Smells terrible, which is consistent with other sprays
  • Kills adults and eggs on contact

Bedlam plus is another top rated bed bug spray. Compared to other bed bug sprays, this product does have a strong odor. Bedlam also has ovicidal qualities as well as acting as an adulticide, which means it can kill eggs and adults on contact.

Apply this product to the harborage areas as well as area you think the bed bugs are hiding and you should be in good shape.


  • Kills On Contact
  • Kills Eggs and Adult Bed Bugs
  • Odor is Not as Bad as Other Sprays
  • 2 Week Average Residual


  • Terrible Fumes, Similar to Other Bed Bug Sprays
  • May Irritate Your Skin On Contact
  • Made from vegetable oil
  • Good track record
  • Targets multiple bug types

Our second pick is a newer formulation made by Rockwell Labs.

It's active ingredient is Esfenvalerate, which is a synthetic pyrethroid (aka a man-made insecticide).

What's special about FenvaStar,  is that it uses "microencapsulation", which makes it easier to deliver a lethal does to your target bug although it doesn't provide that satisfying "quick kill" knockdown you'll find with the over the counter brands.

It's also worth noting that you'll need a pump sprayer to apply the chemical to the bed bug hiding places in your home. Most are cheap and reusable (like this one), so you should have no problem getting one within your budget.


  • Uses "microencapsulation" technology to kill bugs
  • Residual Effect
  • Affordable price point


  • Will not immediately kill bed bugs
  • Odorless
  • A little hard to setup
  • Residual effects

Harris is an odorless, non-stain liquid that you can use to spray your bed and furniture.

You first need to pour the liquid into a smaller container. The product suggests that you use it regularly to get the best results.

Harris usually has powerful effects whilst simultaneously leaving no odors or stains. Yet, (predictably) it doesn’t work against bed bugs that are hiding and may give you a false sense of security. It also requires prolonged periodic treatments. For a full review of Harris Bed Bug Killer click here.


  • Odorless spray
  • Residual effect that can last weeks


  • Slightly complicated setup
  • ​Requires Multiple Treatments And Combination Of Products To Be Effective
  • Kills multiple pests (not just bed bugs)
  • Terrible smells
  • Applies well to carpets and furniture

This one is a little non-traditional since it isn't marketed directly as a bed bug spray.

We found this spray doing a bit of digging and finding what has worked well for others.

A number of users have compared this to Harris and Hot Shot finding it be more effective when applied to furniture, carpets, and other bed bug hiding areas.

The one drawback from Bayer's spray is the significant amount of fumes it puts off. You should always be wearing a fumigation mask when applying insecticides, but with Bayer, it's almost unusable without one.


  • Odorless spray
  • Can Be Used As An Outdoor Barrier
  • Kills Variety of Bugs (Ants, Roaches, etc)


  • The Fumes Are Very Bad
  • The Sprayer Sometimes Doesn't Work
  • A natural alternative (neem oil)
  • Extremely potent odor

Proof is an EPA-approved biopesticide with 5.5% neem oil as the active ingredient. Neem oil is a natural pesticide found in the seeds of a neem tree.

Don't let the word "natural" fool you however, this is still a potent solution that can and will harm you if inhaled by you or your children.

You can use this environmentally friendly bug spray anywhere in your house and it claims to have residual effects that last for a week. Overall, users have found that it does help in reducing bed bugs in and around your house.

Also, despite this product being environmentally friendly, it has an extremely potent odor that requires a fumigation mask and your windows open during use. For a full review of Proof Bed Bug Spray click here.


  • Organic Insecticide
  • Applies Well to Furniture And Other Belongings


  • Terrible Fumes, Similar To Bayer
  • Requires Consistent Application To Be Effective

Our Top Pick: Bedlam Plus Spray

There are a lot of bed bug sprays on the market.

As we were doing research, we were surprised to find so many contenders for the top spots.

Overall, our pick goes to Bedlam Plus.

It has been reviewed, and re-reviewed so many times, and it constantly comes up as a top bed bug killer both as residual solution and contact killer.

Please Note*** If you are attempting to kill or remove a bed bug problem, we highly recommend you consult or potentially hire a licensed exterminator or else you risk making your bed bug problem worse.

    • Hey Bobbie, thanks for the comment. We’ll review it and consider replacing it in our list. Thank you for your feedback!

  1. I personally had a lot of success with the Harris Pyrethroid Resistant bed bug spray. A bit pricey at $60 a gallon but it got rid of what the heat treatment couldn’t.

    • Hi JRD,
      Do you know why your heat treatment didn’t work?I found a co. in Tucson who I guarantees their job for 6 months at $1,800.00.
      I have a 1000 sq home with 2 bedrooms and a living dining, kitchen setting.
      Bed bugs have been confirmed to come from a hotel in Saugus, MA. I slept in July 24, 2018.

      I used Harris back in 2016 with a friend but I’d never heard of heat killing service.
      Nothing kills the eggs but heat, washing EVERYTHING in HOT water and long time hot dry.
      What a pain!!
