Under adequate environmental conditions, how long does it take for flea eggs to hatch?
Answer 2 Weeks
On average, flea eggs take approximately two weeks to hatch when environmental conditions are just right. When temperatures are too cold, eggs take longer to hatch, and when temperatures are warm, the eggs can hatch at a rapid rate.
