If you have bugs in your garden, here's an easy, organic and free way to get rid of them. If you're squeamish about this, put on rubber gloves, garden gloves, or latex gloves and pluck the bugs off the plants, one species at a time, and put them in a cupful of water. You'll get used to it enough to do it bare-handed later, which is much easier. It may sound icky, but it works.
Then take the water and pour it into your blender and blend until you can't see the actual critters any more. Put the water into a spray bottle and spray it on the the same plants you took the bugs from. This prompts a "danger, Will Robinson" response from that type of bug and keeps them away.
Just do one kind of bug at a time, be they beetles, aphids or whatever else you encounter. No pesticides, no traps to empty, just a lovely, bug-free garden. And don't worry about the blender. Wash it as usual and it'll be just fine.

Aphids thrive in temperate regions and feast on plants. They are one of the most pesky and destructive pests that gardeners have to deal with. This page contains homemade aphid spray recipes.
