Neoseiulus californicus - Generalist that Tolerates High Heats
TARGET PESTS
PRODUCT DESCRIPTION
SHIPPED FRESH & QUALITY GUARANTEED
Affordable generalist that tolerates high heats. May perform better than other mites when humidity is lower (between 40-60%).
Neoseiulus californicus, identified by their eight legs and a buff to tan colored pear-shaped body and measuring approximately 1mm. Males are notably smaller and darker compared to females. Well known for their effectiveness in preying upon two-spotted spider mites, Neoseiulus californicus is noted for their ability to endure high temperatures and humidity levels. They sustain themselves by feeding on pollen during periods of low pest populations. Females deposit oval-shaped, translucent eggs beneath leaves and in close proximity to pest concentrations. Within 2-4 days, these eggs hatch into larvae equipped with three pairs of legs, poised to consume spider mite eggs. Progressing through two nymphal stages, they gradually transition to targeting larger-sized spider mite nymphs until reaching adulthood. Adult predator mites, with a lifespan of approximately 20 days, voraciously consume significant quantities of spider mites across all life stages.
BOTTLE vs SACHET / PRO TIPS
Our adult predatory mites are a natural tool to help cure an active infestation of mites. These tiny predators feed on all life stages of unwanted pests in your garden and help to balance the ecosystem. Our beneficial insects work quickly to reduce light to moderate infestations. With heavier infestations, increase in quantity and frequency may be required.
Avoiding garden pests is far easier than dealing with an outbreak of bad bugs - be proactive by preventing the problem. Our sachets are filled with a blend of predatory mites in a variety of life stages, providing a slow release of pest control into your garden. When it comes to having a healthy garden, preventative care is key. Introduce monthly as part of your IPM program.
