Effective September 1, 2005, APHIS will require mandatory methyl bromide fumigation using the T404-d treatment schedule of all bundled bamboo poles and garden stakes imported from various countries upon arrival in the United States. This action is based on multiple quarantine pest interceptions which included Chlorophorus annularis (tiger longhorned beetle) and Niphoma sp.
Previously, bundled bamboo poles and garden stakes did not require fumigation with methyl bromide if they were completely dyed. However, due to interceptions of multiple quarantine pests from dyed bamboos we determined that the dyeing process being used is not an effective treatment to adequately mitigate the pest risk. In addition, many shipments reported as dyed contained both dyed and non-dyed bamboo plant stakes.
Consumers are advised to immediately report any live insects they detect associated with bamboo stakes to State or APHIS offices.
