Alternatively, if your pet or animal in your care is nervous or would not like being sprayed you can use our disinfectant wipes to wipe down the area.

No, Coccidia is a parasite, we cannot test against parasites and disinfectants aren’t effective against most of them. Parasites live inside the animal and treat the animal’s body as a host. They live off the nutrients inside the animal and Coccidia and other parasites can be spread and are most frequently spread by faecal matter. Good housekeeping, in particular, against faeces will stop the spread of it if you have an outbreak or are concerned about the disease.

No, Giardia is a parasite that acts inside the animal. You can help stop the spread of the disease. The spread of Giardia is done by faeces so if you're mindful of the removal of faeces and then disinfect the area this will stop the spread of eggs of the parasite. The eggs of the parasite are contained within the faeces of the animal it has infected so as a general note it is always a good idea to use our disinfectant after you have removed any faecal matter that an animal has left. Faecal matter can attract other organisms and micro-organisms that can cause diseases in pets and humans.

Do a test patch first on an area that can’t be seen.

The laundry liquid is a very powerful product and the guidelines to use it are 10-25ml of the product per kilo of dry weight.

The wipes are made out of a recycled substrate soaked in the disinfectant and so are effective against the same pathogens.

We strongly suggest that if you order our products which have a smaller container (bacterial scrub 500ml, hand sanitiser 600ml and 60ml, trigger sprays, all 1L containers) you keep these containers for future use. It is a good way to save money because the larger versions of our product are more economical and the products have a 2 year sell by date. (bacterial scrub 5L, hand sanitiser 5L refill container and disinfectant concentrate) and then either dilute or refill the other containers. By doing this you'll be helping the environment because our containers are made out of plastic.
