Fleas and ticks are a common pest problem in homes, especially those with pets but you may even have a flea problem even if you do not have pets. Flea bites can cause great irritation to both animals and people and can be difficult to get rid of.
You may kill the fleas or ticks on the cats or dogs but the flea or tick eggs will still be left behind. The flea or tick eggs can hatch over the next 5 to 7 days.
