Management Tips for Pill Bug/Slater

Control:

  • Slaters are easily killed with a direct spray of insecticides either with an aerosol or ready to use pump pack.

  • Preventing the entry of slaters is best achieved by carrying out a perimeter spray with an insecticide (such as a ready to use pump pack), focusing on good coverage at ground level and around potential entry points.

Prevention:

  • As slaters feeding on mulch and decaying vegetation, keep garden beds and mulch away from the perimeter of the house

  • If you do have a garden bed next to the house, use a non-plant based mulch (such as pebbles) and minimise watering (as slaters like moisture)

  • Make sure all cracks and crevices around the edge of the house are sealed to prevent the entry of slaters and other unwanted pests.
