If you’ve ever dealt with fleas, you know just how stubborn these tiny pests can be. Fleas aren’t just an itchy inconvenience — they’re relentless, disease-harboring invaders that can quickly overrun your home. The key to winning the battle? Understanding their lifecycle and how to break it effectively. Let’s walk through what makes fleas so persistent — and how Pasadena Pest Control can help you kick them out for good.
The Four Stages of the Flea Lifecycle
Every flea goes through four stages: egg, larva, pupa, and adult. Knowing how each stage works is critical to fully eliminating an infestation.
1. Eggs
Adult fleas can lay up to 50 eggs a day, most of which fall off your pets and scatter throughout your home — in carpets, pet bedding, furniture, and even the tiniest cracks.
2. Larvae
Within a few days, these eggs hatch into larvae — tiny, worm-like creatures that shy away from light and hide deep in fabrics and floorboards. Larvae feed on organic debris, including the feces of adult fleas.
3. Pupae
Next, larvae spin a protective cocoon and enter the pupal stage. Fleas can remain in this cocoon for weeks or months, waiting for the perfect moment to emerge — when they detect warmth, movement, or even the carbon dioxide we breathe out. In this stage, they are next to invincible and thus the treatment must be planned accordingly.
4. Adults
When conditions are just right, adult fleas pop out, ready to find a host, feed, and start the cycle all over again.
Why Flea Infestations Are So Hard to Eliminate
Adult fleas make up only about 5% of the total flea population. That means 95% of the problem — eggs, larvae, and pupae — is hiding where you can’t easily see or reach.
And it’s not just your pets that bring fleas indoors. There are two primary sources of infestations:
- Pets like dogs and cats can pick up fleas while playing outside and unknowingly transport them inside.
- Rodents and wildlife — like rats, mice, squirrels, racoons, skunks or even opossums — can introduce fleas into your home’s walls, attics, or basements.
Because fleas can hitch a ride on these animals, sealing off entry points is critical. Pasadena Pest Control specializes in professional rodent exclusion inspections, ensuring that rodents and the fleas they carry don’t stand a chance of entering your structure.
