    IPM Recommendations

    • Trap pocket gophers using two-pronged pincer traps in lateral burrows and closed box-style traps in main burrows.
    • Surround trees and shrubs with 3/8-inch hardware cloth.
    • Consider flood irrigation to help control gopher populations, if applicable.
    • Bait larger populations by placing bait directly into burrows.
    • Monitor problem areas to assure trapping and baiting were successful and to quickly control new populations.
    • Carefully read and follow the pesticide label when using rodenticides.
