a simple way to defeat squash vine borers


Squash vine borers are probably one of the most disgusting pests you'll come across in a garden. It's not that the grubs themselves are gross—but the damage they do is surrounded by piles of moist orange frass inside and outside of the hollow stems they consume.

(Frass, in case you've never heard this term, is a funny way to say insect poop.)

Besides being unpleasant to come across, squash vine borers are highly destructive pests and can cause entire plants to collapse before you even realize what's going on. They tunnel into stems and feed from the inside out for several weeks, stunting crops and ultimately decimating them.

Early July is their prime feeding time, and if your summer squash or winter squash plants look wilted no matter how much water you give them, it may be time to take a closer look and see if you've got a squash vine borer problem.

Here's how you can tell if these pests are in your garden (and the one thing you can do to eliminate them).
