Summer and winter squashes, as well as other cucurbits, are maybe bothered by numerous kinds of insects including particular grubs that feed on or bore into the squash vines like wireworms. Properly preparing the squash growing site and detecting excellent sanitation practices can allow you to prevent problems with squash vine insects.
Till the soil to a depth of 6 to 8 inches in the end of this growing season and within a few weeks of planting. Rototilling in the end of this growing season can help to expose larvae or adult insects to birds or other predators and unfavorable weather while tiling immediately before planting can induce eggs or seams farther down into the soil.
Plant a couple of squash plants across the garden as early in the growing season as possible and before planting the actual squash crop and pull up and discard these trap plants if they are at all infested by vine grubs.
Plant the squash seeds or transplants in a different area of the garden compared to the previous year. Rotating squash and other cucurbits with unrelated plants so that squash are grown in a particular site only every three to five years can help to minimize the presence of diseases and insects.
Mound some dirt around the primary stem and over a couple of vine nodes. This promotes secondary rooting and can make it feasible for some parts of the squash vine to survive even if the primary stem is injured by insects.
Rake up or otherwise eliminate all vines and other debris like weeds and mulch in the end of this growing season and destroy or otherwise dispose of all debris.
