Will Lime Dust Kill Fleas That Are in My Garage?

Lime Dust Usage

• Pet Love Shack recommends using lime dust or agricultural lime on moist spaces in your yard, including grassy areas and gardens. The lime slowly dehydrates the fleas, which kills them. Once the fleas die, you simply rake the yard removing any dead grass and the bodies of the fleas. The lime dust dries out nearly anything it touches, including your lawn and garden.

Lime Dust in the Garage

• Lime dust may work at killing fleas in the garage, provided you have access to the fleas. Sprinkle the lime dust around the floor and in any cracks or crevices. Wait several days and check the garage again, looking for any signs of living fleas. If you see fleas, then sprinkle more lime dust. Once the fleas die, sweep the area of any remaining dust and flea bodies. Keep your pets away from the garage until you remove all traces of the lime dust.

Considerations

• Agricultural lime consists of limestone dust or another type of stone dust mixed with different preservatives. Calcium hydroxide is a popular type of lime used in many building products, and is known as slake lime, pickling lime, builders lime and hydrated lime. Some home flea remedies call for calcium hydroxide when mentioning lime dust. Real Country Life calls for slacked or slackened lime in flea remedies for animals.

Warning

• When working with lime dust, make sure that you keep the garage free of water or any moisture. The lime should not mix with water, as it creates a thick paste that does not kill the fleas. Water may also push the lime out of the garage and onto the grass or lawn surrounding the garage. The lime will kill any vegetation that it touches.
