Founded in 2006, the team played in the USL Premier Development League (PDL), the fourth tier of the American Soccer Pyramid, in the Northwest Division of the Western Conference.

The Spiders, under head coach Dan Philp, began quite strongly, beating Tacoma Tide 3–2 and Cascade Surge 2–1 in their first competitive games.

The nadir was a shocking 0–11 defeat to Abbotsford Mariners on the final day of the season, which left the Spiders in 5th place in the standings, 33 points behind divisional champions BYU Cougars.

The high points included a 3–1 win over the Seattle Wolves in early May in which the Spiders took control in the second half after the Wolves' Casey Cunningham was sent off, and the 3–2 win over the Abbotsford Mariners in June in which the Spiders held off two spirited comebacks by the Canadians and scored a 70th-minute winner through substitute Tye Perdido, despite playing for over an hour with 10 men.

Elsewhere, the Spokane defense was horribly leaky: they lost 5–0 and 6–1 to Kitsap Pumas, 5–1 to Cascade Surge, 6–0 to the Vancouver Whitecaps Residency, and conceded four goals on three other occasions.
