Pumpkin Insect Problems


Pumpkins are a favorite food of quite a few insects, and pests on pumpkins can be a real problem. Most, however, are treatable or at least preventable. Here are the most common bugs on pumpkin plants and how to treat them:

  • Beetles – Beetles are the most common but easily treated pests on pumpkins. Spray your vines with a mild pesticide and they should disappear.
  • Snails and slugsSnails and slugs love to eat the tender flesh of very young giant pumpkins. Put a ring of epsom salt or sand around your pumpkin – the pumpkin insect pests won’t cross it. Once your pumpkin’s skin has hardened, they won’t be able to puncture it and won’t be a problem anymore.
  • Squash bugs Squash bugs can destroy stems and leaves and require pumpkin insect control in in the form of Carbaryl, as an effective insecticide.
  • Vine borers – Serious pumpkin insect problems can be caused by vine borers. These creatures burrow deep into pumpkin vines and suck away their moisture. If you find one, you may be able to save your vine by digging the bug out and burying the damaged part of the vine in the ground to encourage it to take root. This is a dangerous business, though, and not always successful. The best thing to do is take preventative measures by spraying the entire vine with a strong pesticide.
  • Aphids Aphids are pests on pumpkins that don’t necessarily do damage except in large numbers, when they can yellow leaves and produce a nasty, sticky substance called honeydew. Even in small numbers, however, they can spread diseases among pumpkin plants. Light insecticides should kill off an aphid infestation, but they can also be combatted by a strong spray of water, the introduction of natural predators like ladybugs, and the installation of reflective mulch.
