CLEANING UP AFTER PARVO

Indoors: Indoors, the virus loses its infectivity within one month; therefore, it should be safe to introduce a new puppy indoors one month after the active infection has ended.

Regular disinfecting using a known parvocidal disinfectant can better guarantee that the indoor environment will be safe.

Outdoors: Proper cleaning and disinfection of contaminated kennels and other areas where infected dogs are (or have been) housed is essential to control the spread of Parvovirus. As the virus is not easily killed it is a good idea to destroy any bedding, or toys and other items that can't be cleaned effectively.

One of the cheapest and most effective disinfectants against viruses (including Parvovirus) is BLEACH (sodium hypochlorite).

A one in thirty two (1:32) dilution of household bleach can inactivate Parvovirus but please be aware of the following points:
As most brands of bleach that you purchase at a supermarket contain varying amounts of the active ingredient (sodium hypochlorite) Please read the label and ensure that the concentration is no less than 5.25%.

If you can only purchase bleach with a concentration less than 5.25%, you will need to recalculate the ratio to ensure that the solution that you are using is powerful enough to kill the virus.

The concentration of the active ingredients in bleach is also known to decrease with age and it does also lose it's potency or effectiveness over time.

It should also be pointed out that although bleach is a powerful disinfectant, it is not a detergent and has has no cleaning power so this means that any soiling or organic matter must be cleaned away before the bleach is able to effectively kill the virus.

It's also important to know that research has shown that the minimum exposure time for bleach to be effective against Parvo, is at least thirty minutes.

There are several more specialised products on the market that are considerably more expensive than bleach but, they are much more effective and these products do not suffer with the same shortcomings as bleach.

These products include Virkon S, Trigene and F10 and it is suggested that you speak to your vet regarding the purchase of one of these products so that you can feel more confident regarding the cleanliness of your dog's environment.
