Flea & Tick Facts
A female can lay about
50
eggs per day
and up to
2000
eggs in a lifetime
The average adult flea life span lasts up to
2
Months
Why killing flea eggs and larvae is essential
Flea eggs and larvae are the first 2 of 4 stages in the flea life cycle. If these two stages are not terminated then larvae will spin silk cocoons and enter the pupal stage.
There are three physical cues that allow a pupa to turn into an adult flea:
- Vibration
- Pressure
- Carbon Dioxide
Basically, cues let a pupa know that its a good time to become an adult, because a host (dog, cat, you) is in the area. Products such as Hartz Ultraguard Pro Flea & Tick Drops for Dogs and Puppies not only kill adult fleas but also the eggs and larvae, preventing future infestations.
The eggs are laid in the pet’s coat and drop off the pet almost anywhere it may roam, especially where your pet sleeps:
Rugs and Carpets
upholstered furniture
cat boxes
kennels
In just 30 days, 25 adult females can multiply into 250,000 fleas.
There are more than
800
known species
of ticks worldwide
