May 17, 2011 – Rodent Baiting Is Changing
QUESTION:
What are the new laws for rodenticides in bait stations for June 2011?
ANSWER:
This potentially is an important change for the PMP, and it is called the Rodenticide Risk Mitigation Decision (RRMD) from the EPA, scheduled to take effect on June 4, 2011, so less than one month away. The biggest effect we will see as professional users of rodent baits is that from that date on the manufacturers will need to relabel their products, including a statement that the bait must be within a tamper resistant station when used outdoors, and this station MUST be within 50 feet of a structure. Fences are NOT considered structures, so baiting a fenceline or some other perimeter of a property with the affected baits will be history.
Another change on rodenticide labels for products for roof and norway rats and house mice is that the label will state "Only" for these rodents, eliminating any vague suggestions that they could be used for other rodent species. This EPA decision addresses all of the current active ingredients used in rodenticides except for a couple of the "natural" actives. It includes all the anticoagulants as well as zinc phosphide, bromethalin, and cholecalciferol. Another change you will see once existing inventories are depleted in our warehouses (and new labeled material is brought in) will be the quantity you must purchase. For professional users the minimum package size for First Generation anticoagulants and Acute toxicants (warfarin, diphacinone, chlorophacinone, bromethalin, cholecalciferol, zinc phosphide) will be 4 lbs. The minimum package size for Second Generation anticoagulants (brodifacoum, bromadiolone, difenacoum, difethialone) will be 16 lb containers. And liquid bait will no longer be allowed for residential use or outdoors.
The retail market will see a bigger change, as consumers have more restrictions. One of the biggest will be that they no longer will be able to buy those Second Generation active ingredients. They no longer will be able to buy pelleted baits, but only paraffin blocks. Package size is restricted to 1 lb. or less and must be sold already within a bait station or with a bait station included.
For professionals we will still have access to all the same bait forms and actives, and it will be the size sold that you notice first. Pay VERY close attention to the labels on the packages that you are purchasing, for you can continue to use your product as labeled. But, on June 4 manufacturers can no longer ship old labeled material, so the new labels will start hitting our warehouses after that. Look on the websites for Bell Labs and LiphaTech and Eaton for summaries of this and updates.
