When do squash bugs attack? if they go for flowers you could try spraying with a strong chili pepper spray or garlic. Aromatic leaves, stems, fruit are usually the plants defense against insects, so anything strong smelling should help - including citronella, mint or lavender type smells. Tobacco juice also works well. Ducks would be my preferred choice though
that would be the best possible solution (not for geodesic designs but for an earth sheltered greenhouse per Oehlers designs)
