Once harvest is complete, remove the squash plants from garden. Plants left in the garden allow the bugs to build up to higher numbers, which will lead to greater problems the following year. Plant varieties of squash that are less sensitive to the bugs. Zucchini seems to be the variety most sensitive to attack by squash bugs. Other summer varieties and most winter varieties seem better able to tolerate feeding by squash bugs.
Squash bugs are active during the day.
At night the bugs hide under boards or other objects. This behavior can be used against them in small scale plantings such as gardens. Squash bugs also seek out sites like wood piles or sheds to spend the winter. Large numbers of bugs overwintering in these sites can lead to high numbers of bugs in your garden the following year.
