Do ashes keep bugs away?
ANSWER: If used judiciously, wood ash can be used to repel insects, slugs and snails because it draws water from invertebrates’ bodies. Sprinkle ash around the base of your plants to discourage surface feeding pests. Once ash gets wet, it loses it deterring properties.

Why is fire non living?
The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells. … Fire does the same thing, but it has no body or has no structured cell system. People think fire is living because it moves and needs oxygen.
