Squash bugs, just like all other bugs, have a life cycle. Adult squash bugs are grayish-brown in color. They are less than an inch long, and some have gold and brown spots along the edge of their abdomen. 

Squash bugs are mistaken for stinkbugs, but stinkbugs tend to be more general and can cause damage to a wide variety of plants.

To be precise, these squash bugs live up to about four months, a hundred and thirty days. Adults lay eggs that are shiny and copper-colored. Eggs get laid late in the spring or early in the summer.

They hatch into nymphs that progressively morph into adult bugs. What is most concerning is that these nymphs, however young, still cause damage to plants.

They suck out the plant juices, feed on leaves, vines and even eat the fruit itself.

  • During the insecticide administration, farmers must be sure to do proper scouting and identify what parts of their plants have significantly been infested. Squash bugs are impossible to pass by.
  • The application involves pouring the Sevin Dust strategically on the plant’s leaves, fruit, and vines. Unfortunately, the bugs’ saliva, which contains bacteria, causes leaf wilts and consequent death in some situations.

It eliminates these bugs by killing them in a brief period and ensuring they do not return. Farmers must look out for eggs that have been laid to destroy them before they hatch.

  • The Sevin Dust Insect Killer can be applied up to one full day before harvest, proving how safe it is to human consumption, unlike other insecticides that require a longer time to wear off.
