Squash Vine Borers Win Again

All my pumpkin plants were decimated by SVBs. I placed yellow pots filled with water all around them to drown them but I caught none. I checked the stems every day for 2 months searching for eggs and saw none. I brushed the stems daily to remove any eggs I may have missed. Mid-July I noticed the leaves turning brown. Yesterday I turned the stems over to reveal all the slits and frass at the very bottom of the stems on the underside where I hadn't been checking. Everything I read says the larvae overwinter in the soil, then fly in July and lay eggs on the plants which become larvae and burrow into the plants. But is it possible that the larvae crawl up from the ground and into the pumpkin plants
