Bed bug sprays help eliminate insects hiding in the baseboards, furniture, and draperies [1]. However, if you want to use one, remember not to go for those with pyrethroids alone since bedbugs are highly resistant to it. 

It would work better if mixed with Allethrin, Bifenthrin, Cyfluthrin, Prallethrin, and Resmethrin to ensure effectiveness. But what causes bed bugs?

How to Use It? 

  • Shake the bottle spray and remove its cap afterward.
  • Determine the bed bugs’ hiding spot.
  • Apply it on bed frames, headboards, bed rails, and upholstered furniture.
  • Remember not to apply the spray near electrical wires or outlets.
  • Allow the spray to dry thoroughly for up to 2 hrs.
  • Make sure to apply the bed bug spray every week since removing the pests may take a while.

Chemicals It Usually Contains 


Pyrethrins are botanical insecticides derived from chrysanthemum flowers. This substance is lethal to bed bugs and can help flush them out of their hiding places [2].


Pyrethroids are one of the highly effective chemicals that can help eliminate the presence of insects at home. However, it is essential to mix it with pyrethrins to make it more effective.


Deltamethrin is widely used as an insect repellent. Its ability to kill bed bugs is proven and tested and promises long-term effectiveness.


Imidacloprid is not only good for killing pests but also for protecting plants. It causes a blockage in a type of neuronal pathway that is present in insects which causes paralysis and, eventually, their death.


Can you use bed bug spray on the bed?

Yes, you can use a bed bug spray in your bed. Just make sure to use a water-based spray or something approved by a regulating body to ensure that it is safe, even with skin contact.

Also, let the chemicals sit for a minimum of 3 to 4 hours before using your bed to rid it of any residue first. But how do you get rid of bed bugs on a couch?

Can you totally eliminate bed bugs with bed bug spray alone?

Yes, you can. However, you need to look for sprays with strong ingredients, including pyrethrins and pyrethroids, to ensure that the bed bugs will be thoroughly eliminated. 

This would also mean you have to spend a lot on these sprays since you have to ensure that all possible hiding spots will be covered. 

Final Thoughts

While bed bugs may be widespread, you do not have to spend your nights scratching their bites and losing sleep. There are products in the market today you can use to prevent and eliminate them, including sprays. 

However, you must ensure that kids and pregnant women are not exposed to it to prevent health problems. If the infestation worsens, it would be best to contact a professional exterminator to help you deal with your bed bug problem.
