Determining how long it takes to get rid of fleas in a house depends on the severity of the infestation and the methods used for treatment. "From eggs to adult fleas, flea infestations can be quite resilient," warns Georgios.
"A full treatment of the entire home and everything in it can get rid of the majority of the infestation within a few days," says Dr. Jonathan Kirby. "But the treatment is only as good as your diligence. Fleas are tiny and therefore hide in the smallest places, plus adult fleas can live for up to 100 days."
"After the initial application, two or more follow-up treatments are needed to eradicate fleas throughout their life cycle," Georgios explains. "Vacuuming and sanitation practices should continue during this time period to remove all remaining flea eggs."
Of course, a severe infestation may take longer, so expect the process to take several weeks to eradicate them entirely.
