1. Sucks the water out of themCedar oil acts to leach moisture from insects' bodies in a process called osmotic dehydration. They basically dry out and die from the lack of water.
Bugs, like people, have particular pH levels their bodies must maintain to carry out normal bodily functions and stay healthy. Cedar oil alkalizes the insects' body serums so they can no longer function and are destroyed.
2. Deacidifies their bodies
Insects need body fat to stay alive, and cedar oil acts to emulsify their body fats (breaking fat globules up into much smaller emulsion), eventually killing the pests.
3. Emulsifies their body fats
By interfering with bugs' normal respiratory functions and causing them great discomfort, cedar oil forces insects to avoid breathing altogether, and they die of suffocation.
4. Causes extreme respiratory irritation
5. Creates pheromonal interferenceThis is the most commonly discussed method of elimination using cedar oil for pest control. Scent-driven bugs, which excludes beneficial insects like bees and butterflies, rely on the compound octopamine for normal bodily functions like breathing, metabolism, reproduction, and movement. Cedar oil blocks their octopamine receptors, and the pests die as a result of the interference.
6. Dissolves pests' eggs, larvae, pupae, and exoskeleton
Cedar oil is able to dissolve pests in their early life cycle stages like eggs and larvae, and it can disintegrate the exoskeletons of adult pests, too. This induces rapid metamorphosis by elevating enzymatic levels and kills the adults pests.
