To get rid of fleas with an easy home remedy, sprinkle boric acid on upholstery and carpets. Using a soft brush, work the powder into the surfaces. After a day or two, vacuum all the surfaces, then continue to vacuum regularly for approximately a month.
- Prepare a boric acid shaker
Purchase a shaker with large holes, such as for spices or sugar, or make one by punching holes in a container's plastic lid. Label the container immediately, as boric acid is poisonous.
- Add the boric acid to the shaker
Put a few larger, clean pebbles into the shaker to keep the boric acid from caking. Fill the shaker about 2/3 full with the boric acid.
- Prepare the target areas
Remove all extraneous items from the areas you are going to sprinkle. Be certain the items, such as toys, shoes or pillows, do not have fleas on them. Replace your vacuum filter to allow for maximum suction, then vacuum your carpet and upholstery thoroughly.
- Sprinkle the boric acid over the vacuumed areas
Test the boric acid on inconspicuous areas of your carpet and upholstery to be sure they do not become discolored. Sprinkle a thin layer of boric acid over all safe areas. Remember to sprinkle under furniture, as well.
- Work the powder into the fabrics and pile
Gently brush the boric acid into the fabric and carpeting. Work it into all of the crevices of the furniture and underneath all of the cushions.
After a day or two, vacuum all of the treated areas again. This removes any visible surface boric acid but leaves a coating within the furniture and carpeting.
- Vacuum regularly
For about a month or so, vacuum every few days to remove the dead fleas that the boric acid has killed.
- Wash the areas
After a month has passed, the boric acid has done as much as possible, so wash the surfaces, if desired.
- Reapply if necessary
Reapply more boric acid to these same areas if fleas are still an issue.
