What we considered in testing bedbug sprays

To identify the top bedbug sprays on the market, we've examined several factors, considering their efficiency, affordability, ease of use, and eco-friendliness. Here's how we evaluated these important criterias:


The best bedbug sprays are usually the ones that are able to kill bed bugs at all life stages, from eggs to adults. We've examined and tested how these sprays eliminate the insects upon direct contact, while also providing residual control in treated areas including furniture and bed frames. Our focus was especially on products that can handle pyrethroid-resistant bed bugs, a rampant problem in many cases.


Bed bugs often demand continued treatment, so it's important the sprays aren't just efficient, but also affordable, offering good value for the price. While we included top-notch professional grade products, we also focused on powerful yet cost-effective bedbug sprays.


The best bedbug sprays should be user-friendly, allowing homeowners easy handling and straightforward application. We examined aspects such as the design of the aerosol bottle, if the sprays are easy to direct into crevices and hard-to-reach places where bed bugs tend to hide, and if the product leaves any troublesome stains or odors. 


An environmental friendly mattress bug spray not only eases the mind, but it's also safe for use around children and pets. Bedbug sprays with natural, non-toxic ingredients were given high regard, particularly those leaving no harmful residue. When it comes to pests, it's always best to keep treatments as safe as possible for the family and the environment.

How to Use Bedbug Sprays?

To make sure you properly eliminate bed bugs, you'll need to know how to use these sprays. This section has all the information you need to make you the best DIY bed bug expert out there!

Prepare the Area

Preparing the space you're going to treat is key. If bed bugs are present in your appliances, especially bed frames and upholstered furniture, it's important first to move these away from walls and other furniture to prevent further issues. Remove all bedding, mattress covers, and cushions, as you'll need to treat these separately.

Empty your closets, as bed bugs often hide in dark areas. Make sure to vacuum all the spots you plan to spray, including hard-to-reach spots. Dispose of the vacuum bag in an outdoor trash bin to ensure you're not bringing these pests right back inside.

Read the Instructions

Always remember to read the instructions provided by the manufacturers. Each solution may have a different formula and specific instructions on how to use it.

Some residual bed bug sprays may need to be diluted with water first or shaken well before use, while others may be ready to apply immediately.

Reading the instructions ensures you're using the product as effectively and as safely as possible.

Wear Protective Gloves

While most bed bug sprays are designed to be safe for home use, it's always a good idea to wear protective gloves when handling these products. The active ingredients in some of these sprays could cause skin irritation.

Wearing gloves will help safeguard against possible chemical exposure, keeping you and your family safe throughout the treatment process.

Apply the Spray

When it's time to apply the spray, focus on the areas where you've noticed signs of infestation, especially crevices and cracks in mattresses and furniture. Spray enough to lightly moisten the place, but avoid soaking it, as this can cause stains and unwanted odors.

Make sure to spray both the topside and underside of your bed frames, box springs, and mattresses. Pay close to attention to corners and seams where bugs like to hide. Bed bug sprays typically kill bugs on contact, so it's important to directly hit as many bugs and eggs as possible.

Maintenance Tips

After your initial spray, continue to monitor and treat the area as needed, based on the product's instructions. Wash your bedding in hot water regularly and use a bed bug-resistant mattress cover to prevent further issues.

Most importantly, seek the help of a professional pest control service for large infestations or if you're not comfortable handling these insects yourself. In the end, a bed bug problem is a battle best fought with all tools and knowledge at your disposal.

How to Choose the Best Bedbug Killer For You?

Shopping for the best bedbug sprays can be challenging, but with a few strategic considerations, you can streamline your decision-making process and choose an effective spray or formula tailored to meet your needs. Let's break it down with a closer look at what to consider.

Type of Bedbug Killer

Bedbug sprays come in various types, each offering unique advantages depending on the severity of the infestation and your personal preferences. We categorize these solutions into 2 main types:

  • Contact Killers: Designed to kill bugs on contact, these come in handy for treating populated areas like bed frames and upholstered furniture. They are often fast-acting, delivering immediate relief.
  • Residual Sprays: These offer long-term effectiveness by leaving active ingredients that continue to kill adult bed bugs, as well as eggs and larvae, even weeks after application. They take the edge off the need for frequent treatments and are a smart choice for dealing with persistent infestations on hard-to-reach spots like crevices and baseboards.

Long Term Effectiveness

It's critical to assess a product's long-term effectiveness in not only killing existing bugs but also interrupting their life stages to prevent further bites and infestations. Products with active ingredients that target pyrethroid-resistant bed bugs and their eggs take the lead here, though solutions that leave no stains or odors behind also score big.


While upscale products often boast advanced features, there's a wide range of budget-friendly options that promise a robust defense against bed bugs. Always consider the volume and concentration of the formula when comparing prices for an accurate value assessment.


The ease of application impacts how quickly and effectively you can treat bed bugs. Aerosol sprays, for instance, are user-friendly and are an excellent option for covering large areas or difficult-to-reach spots. Also, look for products with clear instructions to ensure the safe and efficient use of the bed bug killer.

Safe for Pets

If you have pets, prioritize products labeled as safe for use around pets and family. It's best to opt for non-toxic, natural based bedbug sprays that do not pose a risk of harmful effects if accidentally ingested or inhaled by your pet.

Frequently asked questions

What is the most effective bedbug spray?

When it comes to sheer power and effectiveness, the recognition generally goes to either residual bed bug sprays or contact killers, both have proven to be game-changers. The OnGuard Bedbug Spray is first on the list, with a high-efficiency, both short term and long term.

What is the best way to permanently get rid of bed bugs?

To kill bed bugs, we advise a combination of spray treatments, steam cleaning, and precautionary measures. Use a residual bed bug spray on all possible hiding spots, and if bed bugs aren't gone after a week, either buy a steam cleaner or call a bed bug control expert.

Remember, consistency is key here; intermittent treatment gives chance for surviving bed bugs to multiply.

They usually begin with an inspection to identify the infested sites and follow up with a comprehensive treatment plan. They use insecticide sprays developed for professionals, high-heat steamers to destroy bugs at all life stages, and, sometimes even specially trained dogs for detecting infestations.
