Whitetly infestation of
Ficus trees
lit
For the next six months (until the end of April), the City of lvliami is recommending only natural
controls for the current whitcfly infestation of ficus trees. After six months we will reevaluate
the situation. Six months will allow beneficial/predacious insects to control the whitely
population. We do not recommend spraying trees in urban areas as this will kill beneficial
insects, increase the likelihood of future infestations, and endanger the public. This is consistent
with recommendations from arborists and agencies which we have consulted.
Public Works will not be issuing any tree removal permits for Ficus trees infested by whiteilies.
This position is due to the likelihood of the trees surviving the infestation. IF property owner(s)
would like to remove a dead infested tree. Public Works will proceed asper the Tree Ordinance.
As part of the removal application. Public Works will also provide a list of recommended trees
that will increase the variety of tree species throughout the City and so that future infestations
would he less drastic.
For container plants and small hedges, we recommend an insecticidal soap treatment which can
be purchased at most garden centers. if community members lose hedges. we recommend they
replace them with native hedges such as cocoplum or stoppers. For further information, please
contact your local NET area office, or the Public Works Department at 305-416-1200.
