Diatomaceous earth- is a really abrasive powder found in tooth powder and made from the fossils of diatoms which are really tiny sea creatures.

Once the exoskeletons of any animal is destroyed the animal gradually loses water and dies. You can use this variety of pest deterrent for insects like slugs, millipedes,earwigs, centipedes, cockroaches, silver fish and ants for indoors as well as the outdoors. As the pesticide works mechanically, the insects do not resistant to it and the you can use it again and again.
Garlic based insecticide and pesticides- are the next best things for you to use as pest deterrents. You can use these pesticides to preserve your fruits, vegetables, herbs and other plants. You can use the natural garlic you have with you or use a commercially prepared mixture from an organic manufacturer. A cheaper alternative is to manufacture the mixture at home as follows. Mix up one un peeled onion and one un peeled garlic in to small slivers and then add about one teaspoon of red pepper to boil it in three pints water. Cook for more than 20 minutes on low heat. When the spray cools put in to glass jars and you can store it for more than one month. Dilute the combination with one teaspoon of mixture in one liter of water for best results.
