There are currently no skin repellents that effectively ward off bed bugs, as of 2015. Repellents that can be sprayed on the bed and linens are only effective for two to three hours, meaning they are not very good at preventing bed bug bites.
Although some companies sell organic skin repellents, these have not been found to be effective against bed bugs. Tests have not been done on these products to prove their efficacy. Although the anti-pest sector is continuously testing new skin repellents for bed bugs, none have been proven effective including those products containing orange oil or cinnamon. Moreover, bed bug repellents which can be sprayed on to mattresses and linens are also questionable in their effectiveness. Because they only last for two to three hours, after this period, bed bugs start to bite again. What's more, bed bugs are most active between the hours of 3 a.m. and 5 a.m., which is likely to be long after spraying the bed bug repellents and going to bed. In terms of prevention and protection, people should be viligant when a bed bug infestation occurs, have the home fumigated, and wash all clothes and linens in water hotter than 113 degrees Fahrenheit.
