Recipient of the Your Dog magazine accolade for the best home flea product for an impressive 11 consecutive years, coupled with the Your Cat magazine recognition for an outstanding 7 consecutive years

Indorex House Dust Mites 

House dust mites can contribute to allergic diseases in dogs just as in humans and are one of the most common allergens implicated as a trigger in dogs with atopic dermatitis. Indorex Defence kills these mites and helps to control them in the home for a full 12 months. However, don't forget that the faeces and body fragments of house dust mites are still thought to be potent allergens - to both dogs and humans, so regular vacuuming is essential to effectively reduce their impact.

Can I still see Fleas After Spraying With Indorex?

  • Flea Pupae can remain active for up to 12 months.
  • Vibration, as well as hot humid conditions can cause them to hatch.
  • Indorex Defence will kill newly hatched fleas for up to two months after spraying. 

Trigger the pupae to hatch by:

  • Letting your pet roam the house
  • Vacuum thoroughly for seven days after spraying.

This will allow the pupae to hatch which are then removed by the vacuum cleaner.

Thorough Flea Control:

  • Wash pet bedding on a suitable hot cycle.
  • Spray all the rooms in your house as flea eggs are sticky and will be transferred on clothes.
  • Treat the animal with a suitable flea treatment on a regular basis.

Use a Suitable Flea Treatment on Your Pet

Fleas are the intermediate host for Tapeworm

Use Around Fish Tanks

If you cannot move the tank, Virbac recommend you switch off any pumps and cover the tank completely with 2 thick blankets or cling film to stop any sprayed mist reaching the water. When spraying point nozzle downwards and away from the tank. Ventilate the room after 30 minutes and then remove the blankets or film after two hours and switch the pump back on.

Human Bedding

Fleas cannot penetrate mattresses. Wash bedding, and any mattress protectors on a suitable hot wash, spray the room, and vacuum regularly. 

Children, Babies and Surfaces After Spraying

Indorex has been approved for amateur domestic use. 

Virbac state that once dry, usually with an hour, Indorex Defence has bound to the sprayed surfaces and will not be transferred to skin.
