Fleas can be a major nuisance. Once they hitch a ride on pets into indoor spaces, they tend to linger for a long time. Flea control is about more than killing the fleas themselves--it is also about killing the eggs. Although pet flea medications may kill the fleas present on the animals, they often do little to reduce issues with fleas in carpets and on furniture. Borax works as a flea killer by drying out the fleas, larvae and eggs.
Preparing the Areas for Borax Treatment
Before spreading any Borax on any surfaces, you will need to clean them. Vacuum, wipe down and otherwise clean any surfaces that you are planning to treat with Borax. Pick up any clutter, especially toys. Depending on the method of Borax treatment that you use, you may also need to put up pet gates to prevent pets that groom, such as cats, from ingesting any Borax powder, as it can make pets sick if consumed in large doses.
How to Use the Borax to Kill Fleas
Borax can be obtained at most grocery stores and can be found in the same aisle as the laundry detergent. Don't look for a box of Borax that specifically says that it kills fleas. Any brand of Borax will do, as they are all made of the same thing--boric acid. Sprinkle the Borax on all affected surfaces and let it sit overnight. Vacuum up the Borax the next morning and throw the bag away outside. Repeat every two weeks.
Outdoor Flea Control
If you want to take your flea control outside, you have to use a different method than for flea control indoors. Pure Borax can kill plants in the same way as it kills fleas, by drying them out. To treat yards and other outdoor spaces, according to The Daily Puppy, first, turn off your sprinkler system. Then, combine enough of the following mixture to cover your lawn: two parts Borax, two parts diatomaceous earth and one part salt. Sprinkle the mixture over the affected areas. After a few days, rinse the area by watering it.
