squash bug problems

Asked April 21, 2017, 6:24 PM EDT

For the last 6-8years my garden has had squash bug infestations that I can't seem to control even with Sevin. I was at a seminar last fall where a master gardener spoke and he told me to plant the seeds later on in the season after the squash bugs had completed their cycle. He said they only go through 1 cycle a season and are then gone. I can't remember the date he recommended. Any information on this woujd be greatly appreciated. Thanks

Squash bug can have two generations in MD. There are no easy answers and Planting late will not solve your problem. Cover your plants immediately with row cover to prevent egg laying. However, the row cover will have to be removed when the plants flower for pollination. See more http://extension.umd.edu/growit/beyond-basics/floating-row-cover
Don't apply any mulch around these plants as this gives these bugs places to hide.

Take a look at our pest profile on squash bug for prevention and control. Check seed catalogs for cultivars of summer and winter squash that are resistant to squash bugs. http://extension.umd.edu/growit/insects/squash-bug

Squash is also susceptible to the squash vine borer. It may have 1-2 generations a year. However, you can try a later planting in mid June. See more on the pest profile http://extension.umd.edu/growit/insects/squash-vine-borer
