Chemical pesticides tend to not only destroy destructive insects, but insects that are beneficial to our garden plants. Here are some ideas for natural insect control for keeping those destructive garden bugs under control.
Organic Aphid Spray: Fill a spray bottle (under a dollar at most home improvement and discount stores) with water about 3/4 of the way to the top, add a squirt of biodegradable dish soap, and a couple cloves of garlic, minced. Mix it all together, let it sit overnight for greater strength, and spray it on your plants. You can use it pretty liberally, and you might have to go back a couple of times. The dish soap will kill the aphids and the garlic will deter them altogether.

Keep Spiders Away ~ My Slice of Sunday- not only is this a good way to rid your home of spiders but it really works on wasp...i had a ton of nests in my yard...they are nearly all gone after using this spray. You dont really need the vinegar...2 cups of water..1 tsp of dawn detergent...1 tsp of peppermint oil....and they are gonners, make sure to wait until dusk...thats when they are the least likely to sting you and when they are tired and returning home to sleep.
