According to UC Davis research, apply a spring spray just after the first NOW eggs hatch using reduced-risk products including the insect growth regulator methoxyfenozide, diamide chlorantraniliprole or flubedimide, or spinosyns including spinosad and spinetoram. Use caution since spinetoram and spinosad could be toxic to bees.

Apply spinosad and spinetoram only at night when bees are not foraging. This is effective since NOW moths are typically active at night.

NOW treatment is usually necessary in orchards with more than two mummies remaining after bud swell; less for orchards in the central and southern SJV. Dormant sprays will not control NOW.

Usually only one treatment is necessary to limit kernel damage below two percent at harvest and when nuts are removed before the start of the third flight.

According to the UC Davis paper, NOW control through chemical and cultural methods may be necessary when infested alternate host trees - including pomegranates and pistachios - are nearby.

As these are harvested, NOW moths can migrate into a nearby almond orchard which can make it necessary to treat border rows in the almond orchard. The paper suggests treating at least 10 rows in from the edge of the orchard.

Additional NOW controls include parasitic wasps, including Copidosoma (Pentalitomastic) plethorica and Goniozus legneri. Goniozus legneri is available from commercial insectaries.
