Buying guide for Best bed bug sprays
Nothing will ruin your good night’s sleep faster than an infestation of bed bugs. These insects may be small, but their bites are extremely itchy, and they’re surprisingly difficult to get rid of. You could call an exterminator for help, but if you want to avoid a big bill, you can try tackling the problem yourself with a bed bug spray.
Designed to kill bed bugs on contact, bed bug sprays also prevent new bugs from re-infesting your home. However, bed bugs have proven themselves to be terribly resilient, and some populations have even become immune to some of the most common insecticides. That’s why it’s crucial to choose your formula carefully.
Key considerations
Before you can start comparing different bed bug sprays, you need to understand the type of spray that you need.
Pests killed
Bed bug sprays are typically designed to kill bed bugs at all stages of their life cycle. This should be plenty if your only problem is bed bugs, but if other insects are getting into your home as well, you may want to choose a spray that can combat other pests, such as ticks, spiders, fleas, or cockroaches. The manufacturer should clearly list all insects that the spray works on, so it shouldn’t be too difficult to find one that suits your needs.
Contact vs. residual
The two types of bed bug sprays are contact and residual. Contact sprays are fast-acting, and they kill bed bugs almost immediately. But they degrade quickly and don’t offer much in the way of long-term protection. That’s where residual sprays come in. These take longer to begin working, but they remain effective for several weeks. If you have a bed bug outbreak, it may be wise to purchase a contact and a residual spray to help kill the bed bugs quickly and prevent new infestations. Or you could look for a spray that’s a combination of the two.
Ingredients
For years, the go-to bed bug killer was a pyrethrin- or pyrethroid-based spray. But recently some bed bugs have shown resistance to these products. For this reason, it’s not recommended that you use a bed bug spray that only has pyrethrin or pyrethroid as the active ingredient. Instead you should choose a formula that uses a different chemical like a neonicotinoid (imidacloprid, acetamiprid, etc.) in addition to or in place of pyrethrin or pyrethroid to ensure that you don’t run into any issues with bed bug resistance.
There are also some natural bed bug sprays if you don’t feel comfortable using chemical-based sprays around your home and family. These use geraniol, geranium oil, clove oil, and other compounds to kill and repel bed bugs. However, these sprays are typically not as effective as traditional bed bug sprays, so they’re not a wise choice for a serious infestation.
We find out how well a bed bug spray kills insects at all stages, including the egg, larva, and adult stages. Formulas that address all stages are most effective at getting infestations under control.
Some products we recommend are made of natural ingredients. Although they aren’t as effective as chemical-based formulas, natural sprays appeal to consumers who don’t want to use chemicals in their homes.
We look for sprays with a combination of chemicals that are reliable at killing bed bugs. Options that contain pyrethrin or pyrethroid along with a chemical in the neonicotinoid class work together to kill all stages of bed bugs while preventing resistant infestations.
Contact sprays are formulated to kill on contact, while residual sprays provide lasting protection. We research each type for effectiveness.
We look for bed bug sprays with nozzles that work properly and distribute the product evenly or onto targeted areas.
We look at the amount of product in each container. Smaller bottles are suitable for a few applications, whereas larger containers are ideal for dealing with tough infestations.
We research bed bug spray odors and factor our findings into our recommendations. We consider whether the odor is strong, if it smells like chemicals, and if it would be too overpowering for some consumers.
Product safety is a key element of our research. We want to know if each spray we consider is safe to use around children, pets, and on different types of surfaces.
We research whether bed bug sprays leave behind residue or stains, which can be messy and damaging to some surfaces.
We want to know if a bed bug spray is certified. Certification by the Environmental Protection Agency (EPA) or United States Department of Agriculture provides reassurance of a product’s effectiveness and safety.
Features
Once you’ve decided on the general type of spray that you need, you can start focusing on the details.
Length of effectiveness
Each bed bug spray lasts for a different amount of time. Some contact sprays may only be effective for a few minutes. Residual sprays, on the other hand, usually last at least a couple of weeks, and some may even last up to four months at a time.
But just because one spray lasts longer than another doesn’t mean that it’s necessarily better. However, it does mean that you won’t need to respray as often, which is something to take into consideration. You should be able to figure out how long a bed bug spray is effective by reading the product label or instructions.
Residue
It’s usually best to choose a bed bug spray that dries clear and does not leave stains, especially if you plan to use it on upholstery, bedding, or carpeting. Before you use a bed bug spray, you should read the instructions to be sure that it’s safe to use on specific surfaces and that it won’t leave any visible residue behind or otherwise damage your furniture.
Odor
It’s not uncommon for bed bug sprays, especially chemical-based sprays, to leave an unpleasant odor behind. This should dissipate over time, and you may be able to speed up the process by ventilating the room after you spray. Another option is to go with an odor-free formula. You can get some idea of how strong a bed bug spray’s scent is by reading customer reviews online.
Certifications
It’s best to choose a bed bug spray that has been certified by an organization like the United States Department of Agriculture (USDA) or the Environmental Protection Agency (EPA) as being both safe and effective. Usually, this information is listed on the product itself. Or you can check with the EPA or USDA directly to see which products they’ve approved.
Price
Bed bug sprays range in price from around $5 to over $50. The cost depends on the ingredients, the types of pests killed, and how long the spray is effective. The size of the bottle also matters.
If you’re trying to determine which spray offers the best value, you should compare sprays by price per ounce rather than overall cost. Divide the total cost by the number of ounces to determine the price per ounce. Most bed bug sprays cost somewhere between $0.20 and $0.42 per ounce, but some may cost as much as $1 or more per ounce.
This is one case where a higher price doesn’t always guarantee a better product, though. Base your decision on the product’s ingredients and effectiveness rather than on its cost.

FAQ
Q. Are bed bug sprays safe to use?
A. They should be safe as long as you follow the manufacturer’s instructions and do not touch the spray until it has fully dried. If you’re concerned about the safety of the chemicals in the spray, you may want to opt for a natural bed bug spray instead, although these may not work as well.
Q. How do I use a bed bug spray?
A. The spray you choose should have specific instructions, but, in general, you shake up the spray and apply it evenly across all the surfaces you want to treat. You can also spray it around any cracks or crevices in your home where you feel the insects might be getting in and out or hiding.
Q. Can I apply a bed bug spray directly to my bed?
A. It depends on the type of spray that you’re using. Always read the instructions first. If you can’t apply it directly to your mattress, you can still spray the area around it and dry your sheets at a high temperature to help kill the existing bed bugs.
