How do I control and kill field crickets?

  • Moist harborages, such as woodpiles, rotten landscape timbers, stones, rocks, etc., should be removed or placed away from properties.
  • Yards should be well-maintained, e.g., frequently mowed, weeds should be kept to a minimum, and flower beds should not be over mulched.
  • Exclusion or sealing of entry points into buildings should be prevented by caulking gaps around siding, windows, doors, pipes, wires, etc.
  • Yellow bug-lights or sodium vapor lighting can replace existing outside lighting to avoid attracting crickets to doors or windows.
  • For indoor populations, a vacuum should be used to remove visibly accessible crickets.
