Is 70% alcohol good to kill bed bugs?

A research conducted at Ohio University tested how different concentrations of alcohol can be more effective in killing bed bugs. They used distilled water as a placebo effect, just to confirm if bed bugs would die because of drowning and not alcohol. 

The study was also divided into phases of light, medium and heavy application. Which means with each concentration the amount of substance sprayed on bed bugs was also tested. 

According to the results, the highest mortality of bed bugs in light application were noticed with 70% alcohol concentration. Where 15% of bed bugs died, where other concentrations of bed bugs did not manage to kill any bed bugs.

Keep in mind, these mortality rates are for bed bugs that were directly in contact with bed bugs. There is an even low chance of alcohol killing bed bugs with indirect contact. 

What does 70% alcohol do to bedbugs?

Why makes alcohol toxic for bed bugs? What causes them to die when they get in contact, even if it is a small percentage?

The answer lies in the chemical composition of rubbing alcohol.First of all, alcohol is an amazing solvent. It dissolves the outer shells of bed bugs that are protecting its internal organs.Bed bugs shed their skin throughout their stages of life. Until they become an adult, which is when their shells turn reddish-brown  Once the outer-shell has been dissolved.  It acts as a drying agent also known as desiccant. 

The concentration plays an important role in how quick alcohol dries out the bed bug. With its internal organs collapsing due to dryness and lack of water. The bed bug is ultimately killed. 

The drying effect is the reason why in household items such as sanitizers, glycerine is used in combination with rubbing-alcohol to avoid the excessive dryness of the skin.

Is 91% alcohol good to kill bed bugs?

In the same study conducted at Ohio University. Researchers also tested 91% concentration of alcohol. The results of which were not so tempting in light weight applications.But when researchers tested 91% alcohol with heavy application. 

The mortality of bed bugs increased dramatically to 67 – 85 %. Which is really good keeping in mind it’s just a DIY extermination method you can create and use on your own. 

The results still speak for direct application, this does not apply for bed bugs that got in indirect contact with alcohol. The mortality rate for that group would definitely be lower.

Can I put alcohol on my skin to keep bed bugs from biting me?

There are not many studies supporting the use of rubbing alcohol as a repelling agent. It is a fact that bed bugs can use their sense of smell to identify their prey as well as danger. 

However, it is still not tested if the smell of alcohol would keep bed bugs away from your skin.

Even if alcohol can repel bed bugs. It might not be a good idea to use it regularly on your skin. Alcohol has many properties that can clean and rejuvenate the skin by tightening its pores. 

But continuous usage of alcohol can cause dryness and increased redness of the skin. Any type of usage of rubbing alcohol should always be followed by the usage of moisturizer. 

Will Alcohol Kill Bed bug eggs?

The same study also measured the efficacy of alcohol on bed bug eggs. The efficacy or mortality was measured in terms of hatch rate of eggs. A hatch rate of over 80% was observed in light and medium applications of alcohol irrespective of their concentration. 

A significant increase in mortality of bed bug eggs was noticed in heavy application where over 75% of bed bug eggs didn’t hatch after heavy application of rubbing-alcohol. 

This again proves the strength of rubbing alcohol against insects, but only for instances where you are able to spray alcohol directly on bed bug eggs or the bugs themselves. Which makes it a hard task in itself. 

A better approach of using this treatment is to find the hideouts of bed bugs in daylight. Once you know where the masses of bed bugs hide, you can spray on them directly increasing the chances of mortality.
