Broad Spectrum Sanitiser/Cleaner and Mite Control Agent

Mite Gard Pack ShotMite-Gard is a development of a common technology employing both Quaternary ammonium compounds with a blend of cationic, amphoteric and non-ionic surface active agents and water conditioners with additional poly(hexamethylenebiguanide) hydrochloride.). This gives Mite-Gard an extensive spectrum of biocidal activity in a non-specific mode of action which prevents the problems associated with bacterial resistance. Mite-Gard exhibits stability over a wide range of pH ensuring compatibility with other stages of farm cleanout procedures. Mite-Gard’s most important property lies in its insecticidal activity where kill levels of 100% can be achieved on poultry red mite (Dermanyssus gallinae)1and their eggs without the use of traditional insecticidal compounds such as organo-phosphates and organo-chlorines. The application of Mite-Gard on red mite can lead to erradication, improved bird performance and lower mortality.


Significantly safer than alternative organo- compounds for both humans and birds, with low toxicity.

Significantly safer than dusting products , application actually reduces dust levels in the poultry house.

No special equipment required other than normal workwear and adequate ventilation.

Non-corrosive, non-irratant in the perscribed diluted form.

Full details can be found in the product Health and Safety Data Sheets.

No specific test data on file for toxicology, general toxicological data is available.

Chemical and Physical Properties.

Mite-Gard is clear colourless aqueous blend of cationic, amphoteric and non-ionic surface active agents and water conditioners with quaternary ammonium compounds, polybiguanide hydrochloride and primary fatty alcohol exthoxylate. Boiling point of 1000C, Specific gravity of 1.03, freezing point of 00C and a pH of 12.0 to 12.8. Mite-Gard is generally stable over a wide range of temperatures. Can be inactivated by soap and surface active agents (if in doubt contact the manufacturer).


The formulation of Mite-Gard has been shown in independent trials to have a wide spread biocidal activity against insects, bacterial, viruses and fungi. These are summarised below:

Red Mite Bioassay

Fresh-Shield was applied at various concentrations for exposure times ranging from 4 hours to 140 hours. In comparison with High-cis Cypermethrin, Fresh-Shield showed up to 96.87(corrected mean percent mortality) against 100 for Cypermethrin after 48 hours. Source CVL Weybridge. (Mite-Gard is a more concentrated version of Fresh-Shield, in field tests Mite-Gard has demonstrated similar results at 10% concentration With Mite-Gard the results are instant)

Bacteriacidal activity

Testing against Vancomycin resistant Streptococcus faecalis (Vancomycin resistant enterococcus,VRE) and Methicillin–resistant Staphylococcus aureus at a 10% solution, showed the formulation of Mite-Gard to be highly effective (European Suspension Test). Source University of Leicester. The trials were summarise by Professor Steven Myint , Professor of Clinical Microbiology as follows:

“At 1:10 dilution both solutions have bactericidal activity against MRSA and VRA in the presence of a small amount of protein. This would be consistent with adequate disinfection in the presence of low levels of organic materials.”

When tested against Mycobacterium smegmatis (an organism with identical physicochemical properties to Mycobacterium tuberculosis) the conclusion to the trials were that the product was “effective at 10% dilution.”

Using a modified Kelsey Sykes test (BS6905:1987), the formulation of Mite-Gard was tested for efficacy against Listeria monocytogenes ATCC 19117, Salmonella typhimurium NCTC74, Pseudomonas aeruginosa NCTC6749,E. coli NCTC8196 and Shigella sonnei ATCC25931. The trial conclusions were that “the disinfectant passed the challenge tests on three successive occasions at its in use concentration. Source Microspec Laboratories Ltd. It should be noted that the modified Kelsey Sykes test takes account of organic debris.

Virucidal Activity

The formulation of Mite-Gard was tested against Poliovirus type 1, Herpes simplex type 1 and human type Hepatitis B virus. Source University of Leicester. The trials were summarise by Professor Steven Myint , Professor of Clinical Microbiology as follows:

“In conclusion, at supplied concentration, the product has virucidal activity within a sixty minute exposure period. In the case of Hepatitis B, this is in the presence of serum.” And “It is, however notable that the results of these disinfectants were superior to those obtained for a hypochlorite-containing compound PreseptR”

Fungicidal Activity

Testing against a clinical isolate of Trichophyton rubrum using a modified Kelsey Sykes (modified from BS6905:1987 to allow anti-fungal activity to be assessed), showed the formulation of Mite-Gard to pass the test on three successive occasions. Source Microspec Laboratories Ltd.

Instructions For Use

Stage 1: Before de-population of the unit, spray liberally with a 10% solution of Poultry-Shield to equipment and nesting areas. (This also gives a comfortable environment when removing equipment manually)

Stage 2: Remove all equipment from the unit (free-range) and all plastic slats, as interlocking joints can harbour eggs and immature mites.

Stage 3: The unit and equipment must be washed to a clinical standard removing all litter and manure from every area; thus removing as many mites as possible.

Stage 4: Once the new crop of birds are in and the unit temperature is as required, spray with a 10% solution of Poultry-Shield as mites will become very active especially if the unit has been empty for a long period of time.

Stage 5: Routine Spraying with a 10% solution must be done every 4-6 weeks without fail, even if mites are not visible.


Mite-Gard is manufactured in a ISO 9001 accredited production plant and is registered under the European Biocidal Products Directive under BAC50 EINECS (registration number 273-544-1).


Containers should remain closed in storage, at ambient temperatures in a dry environment.

Shelf life

Mite-Gard is a stable product without an applicable shelf life. No decomposition if stored and used as directed.


Disposal of the concentrate should be via a licensed waste disposal contractor to an approved waste disposal site. Mite-Gard should be categorised by use as a hazardous waste.


Available in 4 x 5 litre case, 20l and 200l drums and in 1000 litre IBCs.

Ecological considerations

Mite-Gard is soluble in the aqueous environment and may cause detrimental effects due to surface active ingredients, like other soaps Polybiguanide is slowly degradable in water. The product is predicted to have low bioaccumulation ability.

As environmental legislation becomes tighter the use of these traditional insecticides will become more difficult to use while Mite-Gard provides a scientifically proven alternative with low environmental impact and low mamallian toxicity.
