As an expert in entomology with a focus on household pests, I can provide you with information on natural repellents for bed bugs. It's important to note that while certain scents may deter bed bugs, they are not a comprehensive solution to a bed bug infestation. Professional extermination methods are often necessary to fully eradicate these pests.

Citronella oil is one of the most commonly recommended natural repellents for bed bugs. Its strong lemony scent is believed to be effective in keeping bed bugs at bay. However, it's crucial to apply it regularly and in sufficient quantities to maintain its effectiveness.

Eucalyptus oil also has a strong scent that some studies suggest can deter bed bugs. Like citronella, it needs to be applied frequently to be effective.

Peppermint oil is another option. Its pungent odor can be a deterrent to bed bugs, but again, it must be used consistently.

Tea tree oil is known for its antimicrobial properties and is also thought to repel bed bugs.

Remember, while these scents can help deter bed bugs, they are not a substitute for professional pest control services. If you suspect a bed bug infestation, it's best to consult with a professional exterminator.
