There are several bugs that can affect pumpkins, including cucumber beetles, squash bugs, vine borers, and aphids. To control these pests, you can use a variety of sprays, depending on the type of bug you are dealing with. Here are some options:

• Cucumber beetles: Spray with imidacloprid (Admire Pro) or dinotefuran (Venom or Scorpion) to prevent flaring aphids. Carbaryl is also an effective insecticide for controlling cucumber beetles.

• Squash bugs: Use Carbaryl as an effective insecticide.

• Vine borers: Spray the entire vine with a strong pesticide.

• Aphids: Use neem oil or insecticidal soap for bugs and aphids, or light insecticides to kill off an aphid infestation.

Its important to note that some insecticides can have detrimental effects on bee populations, so its best to use them sparingly and follow all directions and precautions. Additionally, its a good idea to determine the cause of your pumpkin problem before deciding on a spray.
