How to Make DIY Non-Toxic Insecticide Using Diatomaceous Earth

Why Diatomaceous Earth?

The best and safest way to rid your household of any troublesome pests. Too good to be true? Apparently not. Diatomaceous earth, also known as DE is a powdery compound made up from the ground-up bodies of prehistoric diatomic algae fossils known as diatoms. When DE is ground up the tiny skeletal diatomic pieces become very sharp (at a microscopic level). They produce the same effect many microscopic razors would, cutting into lung tissue, mucous membranes and breathing holes in insects or bugs. These microscopic cuts in bugs help leech out their moisture, drying them out. DE is also effective against snails and slugs, drying them up as well as worms, mites, fleas, beetles, and almost any spider or insect. Diatomaceous earth is also safer around other wildlife, children and pets (as long as DE dust is not inhaled) as it is 100% natural and does not contain any nasty chemicals or poisons. 

Indoor Uses

Similar to other home solutions DE is something you can mix in with water and simply spritz. However, there are many accounts that state Diatomaceous earth works best when it is dry. This can be a relief for many as DE can simply be vacuumed up when used in the home. DE can be sprinkled on carpets, regular bedding, as well as pet bedding and any corner of concern in the house. Allow for a minimum of 12 hours for the DE to sit on the fabric and do its job before vacuuming up. Additionally, diatomaceous earth can also be used on your pets! It's incredibly helpful in keeping any unwanted pests away including fleas, worms and lice.

Diatomaceous Earth Spray Recipe (Preferably Used on Any Indoor Plants)

  1. Add 1 tablespoon of diatomaceous earth into a one-litre container of water with a lid that seals tightly. 
  2. Screw the lid on and shake vigorously until the DE dissolves into the water.

Note; The DE will separate and gather at the bottom of the container. Make sure to continuously shake whilst in use to ensure effective application.

  1. Spray the plants with a fine mist until they are wet but not dripping. Spray the undersides of leaves too.
  2. Allow the plants to dry. As the water evaporates the DE is left behind as a protective barrier that adheres to the plant’s leaves and stems.

Diatomaceous Earth Pet Dust Bath Flea Treatment Recipe

  1. Measure out enough DE for your pet, make sure it is a sufficient amount for rubbing into your pet’s fur and areas of concern (varies depending on pet size).
  2. Dilute the DE with another powdery substance such as arrowroot. This will help prevent any discomfort in your pet.

Note; Be sure to avoid the eyes and mouths as DE can cause discomfort from dryness.

  1. Be sure to treat any pet bedding, carpets, furniture and any other area your pet comes in contact with as it is likely to be infested as well (these other areas do not require the DE to be diluted). 

Outdoor Uses

For outdoor use, DE can just be spritzed with the recipe above or sprinkled out in your back garden or on a raised bed of greens. Diatomaceous earth must be reapplied after every rain or heavy dew for it to be effective. This works out perfectly, as DE can be spread in the mornings right on the dew itself or right after the rain has ebbed, helping the DE to stick and dry on more surfaces, plants and shrubs. Please note that the use of a dust mask is advised and the area should be kept clear of pets and children until the DE dust has settled.

A word of caution to all those looking to start using DE regularly in and around their homes. All diatomaceous earth is not made in the same way. It is very important to make sure that when shopping for DE make sure that the package it comes in states that it is ‘food grade
