Tobacco Sprays and other natural pesticides

Tobacco Sprays and other natural pesticides

I was planning on putting together a spray for my vegetable garden made up of tobacco, garlic, pepper.. soap (using a recipe I found online) to control bugs on my veggies. However, How good are these sprays for. Not just on the plants themselves but how long can I keep them in the bottle.? a day, week, Year? I want to know how much I should make up for my first batch and I don't want to waste any. Thanks
