The Hop Louse Sabotage
A breakthrough in the Puyallup Valley reveals the hidden life cycle of the pest destroying Washington's hop industry.

Henry Bucey, president, and C. A. Tonneson, secretary of the state board of horticulture, believe they have confirmed a valuable discovery in connection with the hop louse. A few days ago, a hop rancher residing between Tacoma and Seattle sent to the state board a small quantity of earth taken from a hop field. He called attention to the presence of the 'stem mother,' or the egg-laying louse, in this earth. Heretofore, the louse has been attacked on the theory of United States Entomologist Riley that the louse wintered on vines and trees, especially plum trees. Mr. Bucey and Mr. Tonneson went up the Puyallup valley today and found as many as sixty stem lice in the ground about the foot of a hop pole. They were found huddled and partially numb from cold, in a thin coating of white fuzz. Mr. Tonneson said: 'If it is proven that the lice winter in the ground, then they will be attacked upon an entirely different plan. Now we shall treat the louse while he is in the ground, and every stem louse exterminated means the keeping out of existence at least 50,000 lice for the season following its extermination.' By plowing some lime in the hop hills in the fall, the process of percolation will kill the stem louse.
“Every stem louse exterminated means the keeping out of existence at least 50,000 lice for the season.”
In the 1890s, Washington was a global leader in hop production, and agricultural pests posed an existential threat to regional economic stability. Today, while hops remain a cornerstone of the Pacific Northwest brewing identity, the struggle continues as growers battle modern pathogens and climate volatility, proving that the health of the harvest is still a vital civic concern.
