Flea pupae are unaffected by any insecticide flea spray. These pupae can survive in the house for
over 12 months but do hatch in response to vibration, especially in warm humid weather. These newly hatched fleas will be killed within 24 hours by Indorex Defence for up to 2 months after application. The hatching process can be accelerated with warmth and vibration by:
Allowing your pet to roam around your home
Turning up the heating
Thorough vacuum cleaning for 7 consecutive days, as the movement and vibration encourages the pupae to hatch, which are then removed by the vacuum cleaner
