So here are some tips for organic, preventative pest control:
1) The War of Ladybeetles and Aphids
Everyone loves ladybeetles (also called ladybird beetles). Children pick them up in awe, and some cultures associate the beetle with good luck. However, seeing ladybugs also mean that aphids--their main food source--are in the area. Thin white filaments on budding leaves or flowers also mean aphids, and they are often called plant lice because they live in hoards and are hard to completely remove.
For a short-term solution, aphids can be washed off with water. Another way of removing them is simply to get rid of any infested leaves and care for lacewing and lady beetle populations. Preventative measures include planting chives or garlic close to the plant you want to protect, or even planting banana peels in between the desired plants. Some websites recommend using an oil-and-water mix spray in the place of pesticides, such as orange oil mixtures.
2) Leaffooted Bugs can rasp the life out of your plants.
3) Mealybugs can cause plant wilting.
Know how pests consume produce.
The three insects listed in this article are all bad because of their mouth apparatuses. They all have a proboscis that is harder than a butterfly's or a moth's, made for piercing leaves. Aphids, Leaffooted Bugs and mealybugs all cause some damage because of the way they eat produce, by digging in and sucking away nutrients. In some cases the damage is only superficial, like the discoloration caused by the leaffooted bug. However, mealybugs and aphids both cause significant damage by swarming in large numbers onto leaves and drying them up, preventing the plant from thriving. Using flowers to attract natural enemies, like marigold for lacewings, can be another help to protect what you grow.
