Simply put it in the kitchen

Vegetable glycerin: Not necessary, although it may help keep the repellent on the skin longer and moisturise it.
Water: To dilute the mixture, use distilled or boiling (cooled) water.
Making Your Own Repellent
Mixing Essential Oils: Combine 30 to 50 drops of the essential oils of your choice in a spray container. The repellant will be more potent the more oils you apply.

Add Witch Hazel or Alcohol: Pour witch hazel or rubbing alcohol into the bottle until roughly half of it is filled.
Add Water: Pour the remaining water into the bottle. To allow the mixture to be shaken, leave a little gap at the top.
Optional Addition of Vegetable Glycerin: If you have dry skin, mix in one teaspoon of vegetable glycerin. While not necessary, this step will help to hydrate your skin.
Good Shake: To make sure all the components are well combined, tighten the lid and give the bottle a good shake.
Test and Use: Perform a patch test on your skin before to applying the repellent to make sure there won’t be any allergic reactions. When necessary, mist the repellent on exposed skin or clothes after testing it. For best results, reapply every few hours.
Extra Advice: To maintain the repellent’s effectiveness, keep it in a dark, cold area.

The oils and water might separate, so don’t forget to shake the container before using it each time.
Consider adding window boxes or other bug-repelling plants like citronella, lavender, and marigolds to your kitchen for further security.
You may avoid using chemical alternatives and maintain an insect-free kitchen by creating your own natural repellent. Just keep in mind that for optimal effects, natural repellents may need to be used more regularly. So why not give it a go and take pleasure in having your kitchen bug-free?
