HOMEMADE ORGANIC PESTICIDE RECIPES AND NATURAL REMEDIES:
There are lots of organic pesticides now available at lawn and garden centres, but many can be made easily at home. While these natural mixtures are biodegradable, use them sparingly, since they will kill the good bugs such as spiders and ladybugs, along with the bad ones.

Rhubarb insecticide
Boil 500 grams of rhubarb leaves in a few pints of water for about 20 minutes, allow to cool, then strain the liquid into a suitable container. Add some dish detergent or soap flakes (not laundry detergent!) and spray on leaves to kill off all kinds of bugs like aphids and spider mites. * NOTE: Rhubarb leaves contain high amounts of oxalic acid. If ingested, your heart will stop and you will die.

Garlic and soap insecticide
Pulverize in a blender a couple of whole cayenne peppers, a large onion and a whole bulb of garlic with a little water. Cover this mash with a gallon of water, let stand 24 hours and strain. Spray daily on roses, azaleas, and vegetables to kill an infestation of bugs. Don't throw away the mash; bury it among the plants where insects occur.

All-purpose weed killer
Boil a litre of water, add 2 tablespoons of salt and 5 tablespoons of vinegar. Pour directly on weeds on sidewalks, driveways, etc. while still hot.

Animal repellent sprays
Cats: two parts cayeene power, three parts dry mustard powder, five parts flour and add sufficient water.

Dogs: mix together one garlic, one medium onion, one litre water and 15 ml Tobasco sauce.

Squirrels: blend together 15 ml Tobasco sauce and chili powder, 5 litres water and a dash of dish soap.
