The Q&A Archives: Pests

Question: I keep getting little green caterpillars on my Roses, I spray according to insecticide (5-7 days)directions but it is really getting expensive. What are they and can I keep them away permanantly ?

Answer: Caterpillars are the larvae of either butterflies or moths. You may have a shrub somewhere in your garden that's attracting these adults and they then lay their eggs on your rose bushes. Unless you can identify the caterpillar and find the source, you'll just have to keep treating your roses. You can handpick and destroy these pests or use Bt (Bacillus Thuringiensis) to control them.
