Other substances

5. Soap spray

Physical control

1. Water spray
   Spray a steady stream of water on the host plant to knock-off aphids. Once on the ground, the fallen aphids are prey to ground predators and they have difficulty returning to the plant (Ellis;Bradley: p. 433).
2. Water traps
   Half-fill yellow pan or basin with soapy water. Place the pan close to the plant but exposed enough so that aphids will see it. Trapped aphids sink and drown because soap breaks the surface tension of the water. The yellow color attracts the pests (Ellis;Bradley: p. 440). However, if more beneficial insects are trapped, stop using this, as beneficials might be sufficient enough to control the pests.
3. Handpicking
4. Pruning
5. Sticky board traps
   Aphids are attracted to yellow color.
   To make your own sticky trap, spread petroleum jelly or used motor oil on yellow painted plywood, 6 cm x 15 cm in size and up. Place traps near the plants but far apart enough to avoid leaves sticking to the board (Thomas, 2002).
