Types

• According to North Carolina State University, pests like aphids, stink bugs and corn earworms eat okra. However, the pest that causes the most damage is the Japanese beetle.
  
  

Control

• Organic control of Japanese beetles can be effective but also take some time, according to the USDA. One option is using Milky Spore, which kills beetle grubs, but it can take many years for it to be effective. You can also use nematodes, which are microscopic roundworms that kill Japanese beetle grubs by infecting them with a bacteria and then eating them.
  
  

Oil

• Placing a few drops of corn oil or mineral oil on your okra will prevent pests like the corn earworm from laying eggs on your vegetables. If larvae have already hatched, they will not be able to get around the oil drops. You only need to apply the oil once.
