How to eliminate gamasid mites if there are rats in the house?

If there are rats in the house, there may be gamasid mites, as they mainly parasitize rats. The core of eliminating gamasid mites is to eliminate the rats first.

Step 1: Eliminate rats

  • Identify rat entry routes (wall holes, pipe openings, door/window gaps) and seal them.
  • Use traps or glue boards.
  • Clean up scattered food scraps; seal garbage in containers.
  • Focus on areas where rats are active: under cabinets, under sinks, behind refrigerators.

Step 2: Clean the environment

  • After rats are gone, mites without blood meals will not survive long.
  • Thoroughly sweep and vacuum areas where rats were active—under kitchen cabinets, along pipes, near wall holes.
  • Also clean dust and debris near rat nests.
  • Seal and discard the vacuum bag to prevent mite spread.

Step 3: Chemical control

  • Carefully spray areas where rats have been active with household hygiene insecticide containing deltamethrin.
  • Focus on: wall bases, baseboards, around pipes, storage room corners.
  • Once dry, the insecticide forms a film; stray mites that crawl over it die.
  • Residual effect lasts 2-4 weeks.

Step 4: Ongoing prevention

  • Keep the indoor environment clean and dry to reduce rat hiding places.
  • Do not stack garbage or debris near the foundation outdoors.
  • Regularly check for new signs of rat activity (droppings, gnaw marks, etc.).
