NZMS Sanitizing Update:
These Mudsnails are now in all 10 western states.
Many of us have been using the wrong Formula 409 product for killing New Zealand Mudsnails attached to our wading equipment.
â€śCOMMERCIAL SOLUTIONS FORMULA 409 CLEANER DEGREASER DISINFECTANTâ€ť
The above 409 product is the only one that was used in the California Department of Fish and Game field test report released in 2005. This product will not be found in grocery stores as it is a commercial product but it can be found in Home Depot and Loweâ€™s, Office Max and Office Depot. Unfortunately, the manufacturer has recently discontinued this product but it is still available in places. The only other product that has the same disinfectant in it is:
â€śFormula 409 All Purpose Cleaner Antibacterial Kitchen Lemon Fresh.â€ť - Available in many places but in small bottle sizes only
Key words to look for = Disinfectant or Antibacterial
Please make sure you are using the correct products, as other 409 products are not killing the snails though they do aid in washing them off your equipment. Other Manufacturerâ€™s products with disinfectants have not been test or failed test for either not killing the snails or for damaging wading equipment.
Water based solutions with Copper Sulfate and Sparquat 256 are two solutions proven to be more effective than formula 409 solutions; Availability of these products is some what limited.
see website below.
Ask your local tackle shop to start carrying some of these products. It is in their best interest to help maintain the quality of our fisheries.

about known sources for all the products, pictures of the correct product, detailed sanitizing protocols, and New Zealand Mudsnail information see this web page.
Always cleanse your wading gear before moving from one body of water to another body of water. No one will know a location is infested until long after the snails are well established.
