Tricks for removing aphids, mites, and other small insects
Scientists at Texas A&M University estimate that up to 90 percent of problems with aphids, mites, and spittlebug nymphs can be cured by dislodging them with a strong blast of water. You can also use adhesive tape to remove aphids and other small insects from plant leaves. Simply wrap a long piece of tape around your fingers (sticky side out), and blot off the bugs.
For aphids in particular, set a yellow dish filled with soapy water near the plant. Aphids are drawn to the color yellow. For spider mites that persist despite a daily spray of plain water, use a buttermilk spray developed by scientists at Purdue University. Combine 1/4 cup of buttermilk and 2 cups of wheat flour in 2-1/2 gallons of water. Pour the mixture into a spray bottle, shake the ingredients thoroughly, and spray it on your plants.
