Another highly effective treatment is diatomaceous earth. This fine natural powder consists of microscopic abrasive particles that damage the outer shell of bed bugs, causing them to dehydrate and die within hours. Lightly sprinkle food grade diatomaceous earth under the bed, along baseboards, behind furniture, and in any suspected hiding spots. Always use the food grade variety to avoid respiratory risks and apply it carefully to minimize airborne dust.
Strong scents also help repel bed bugs and interfere with their ability to navigate. Garlic and certain essential oils, especially lavender, tea tree, and eucalyptus, are known to disturb these pests. A simple natural spray can be made by mixing twenty five milliliters of lavender essential oil, fifty milliliters of tea tree oil, and one liter of water. Shake well and spray mattresses, linens, furniture seams, and dark corners where bed bugs might hide. Regular application enhances effectiveness.
