Answer:

Lynn,

There isn't one specific plant that will repel all insects, but in general, strong-smelling plants seem to work better than odorless plants. The idea is that some insects use scent to locate their host plants. If strong-smelling plants are growing nearby, the insects are more likely to become confused and move on. Try interplanting tansy, pennyroyal, lavender, peppermint (and other mints), onion, garlic and marigold.

Mixed planting is another effective strategy for controlling insects. By mixed planting, I'm referring to growing a diversity of plants rather than growing just a few types of plants. This encourages the pollinators and works to attract the kind of predatory (beneficial) insects that will naturally prey on pests. Mix planting also discourages pests from laying eggs. Many insects taste with their feet. If they land on several suitable plants in a row, will stop to lay their eggs. If they land on several different (unsuitable) plants in a row, they are more likely to move on and look elsewhere. One example of mixed planting is to plant flowers around vegetables in the garden.
