Real NephiFIX

Nephus kamburovi

Real NephiFIX (Nephus kamburovi) are predatory beetles, indigenous to South Africa, that prey on mealybug & other insects such as Cochineal and some soft scales. These beetles are high-density feeders with a voracious appetite for mealybug, therefore they are perfect for use in hot spots.

Mode of Action

Effective against:

  • Vine Mealybug (Planococcus ficus)
  • Citrus mealybug (Planococcus citri)
  • Long-tailed mealybug (Pseudococcus longispinus)
  • Oleander mealybug (Paracoccus burnerae)
  • Citrophilous mealybug (Pseudococcus calceolariae)
  • Pink hibiscus mealybug (Maconellicoccus hirsutus)
  • Also closely related mealybug & some soft scale including hemispherical scale.

Real NephiFIX:


Real NephiFIX are best released in spring & early summer, before mealybug populations build up to high levels. Winter releases are not recommended due to low temperature and the consequent reduction in mealybug populations.


Real NephiFIX is a robust beetle that works effectively between temperatures of 18 - 38 degrees Celsius.
