Along with the heat of summer, pests emerge more prevalently in your landscape or clients’ lawns. While we recommend using pesticides such as Bayer Advanced Natria Multi-Insect Killer, it is important to keep the beneficial bugs in your yard. Choosing the right pesticide will often ensure the good bugs stay alive. However, you can grow certain plants to attract the good bugs. How can you differentiate between friend or garden foe? We have created a simple list to help you discern helpful bugs from harmful pests.

Beneficial bugs:

The below list of bugs will help eradicate the pests in your yard as a natural pesticide.

  • Lacewings: adults and larvae eat aphids, caterpillars, mealybugs, whiteflies and more
    • Plants that attract them: angelica, cosmos, sweet alyssum and coreoposis
  • Syrphid Flies: larvae eat aphids, and adults hover around flowers. They look like wasps, but only have two wings versus four on harmful wasps.
    • Plants that attract them: oregano, garlic chives, sweet alyssum, buckwheat or bachelor button
  • Lady Beetles: adults and larvae eat aphids, mites, and mealybugs
    • Plants that attract them: angelica, coreopsis, dill, fennel or yarrow
  • Parasitic mini-wasps: they lay their eggs in pests such as aphids or caterpillars. Once hatched, the larvae eat them.
    • Plants that attract them: angelica, chervil, fennel, dill, and cilantro
  • Spiders: all spiders feed on harmful insects or other arthropods
    • Attract spiders by adding a loose layer of mulch by adding coverage from the elements.

Harmful Pests:


  • Sod Webworms
    • The larvae feed mostly on cool season turf grass, causing dead brown spots.
  • Billbugs
    • Adults females cut small holes in the stems of plants to lay their eggs
  • Crickets
    • They eat fruit, seed, leaves, other insects, or nectar.
  • Fall Armyworms
    • Larvae feed on grasses and other low-growing plants. Later in the season, they make holes in plant leaves and fruit.
