i'm watching my squash very carefully; so far i've seen one squash bug. i went out with a spray bottle of soapy water and looked under every single leaf: no eggs and no sign of any other squash bugs. i have twelve beautiful squash on the vine, getting big. i hand-pollinated all of them. i'm terrified of them being attacked. if i just pick them when they're big, will they ripen by themselves like tomatoes will?
