Control spider mites in warm, dry climates! Similar to P. persimilis, but effective in lower humidities.
Identification: Mesoseiulus longipes are pear-shaped predatory mites measuring roughly 0.5mm in length. Coloration varies from beige to amber/red. Females are the predominant sex with a ratio of 4 females to 1 male.
Preferred Food: M. longipes is frequently used for control of spider mites in hot, dry greenhouses as they consume egg, nymph and adult stages. Similar to P. persimilis, M. longipes feed faster than other mite predators.
Optimal Conditions: Use these beneficial mites with in warm conditions with moderate humidity (65-90°F, RH 40-60%). M. longipes are effective in temperatures up to 100°F, although a comparable increase in humidity is required. Apply these predators in warm greenhouses and interiorscapes with artificial lighting or in outdoor settings with suitable conditions. The lower humidity needs of M. longipes make it ideal for controlling spider mite infestations on taller plants in greenhouses.
Release Rates: Some crops, including tomatoes & other highly resinous crops, require higher release rates.
- General Releases – 2,000 per 3,000 sq. ft. bi-weekly, 2-3 times for most greenhouse crops.
- Horticultural Releases/Bedding Plants – 1,000 per 10,000 sq. ft. biweekly.
- Indoors – 3,000 per 1,000 sq. ft. bi-weekly, 3-5 times.
- Large Scale Releases – 5,000-20,000 per acre depending on infestation level.
Mesoseiulus longipes do not do well in outdoor settings. Release should be made indoors or in greenhouses for best results.
PLEASE NOTE: All Mite Predators require additional processing time due to rearing and collection times. Additional information can be found on the Shipping Tab to identify the earliest shipment date. If you have questions about shipment dates, orders can be placed with our sales representatives at 1-800-827-2847.
This Product Controls These Pests or Diseases: Spider Mites (Mult), Two-Spotted Spider Mite (Tetranychus urticae)
M. longipes are effective predators of multiple species of spider mites and can be used alongside P. persimilis. Release instructions can be found below. If you are a first time user of M. longipes mite predators, please call us at 1-800-827-2847 to walk through application instructions and best practices.
M. longipes are shipped in loose media designed to be broadcast directly onto foliage of spider mite infested plants. Concentrate releases on high-density pest populations first and foremost. Spread as evenly as possible throughout the growing area for preventative releases.
Avoid applying to flowers as the medium can stick to pollen, nectar and/or resin. It may be beneficial in hot, dry environments to mist down plants prior to releasing M. longipes. This will increase the relative humidity in the areas surrounding the plants and can help mite predators adapt rapidly to their new environment. DO NOT spray insecticides after releasing M. longipes.
Environment: Indoor Crops, Nursery, Greenhouse, Grow Room, Hydroponics, Aquaponics, Interiorscapes, Container Plants
Storage: If not releasing immediately, keep in a cool dark place out of direct sunlight. Do not refrigerate.
Viability Note: If you plan to check for viability, please do so upon receipt and prior to releasing the beneficial insects. Many predators and parasites are small and can be difficult to spot once released. If you believe there are issues with viability, please contact us at 1-800-827-2847 or customercare@arbico.com.

What's In The Package: M. longipes are shipped as adults ready to be released upon delivery.
- 1,000 ct. – 1 oz. bottle mixed in corn grit.
- 5,000 ct. – 4 oz. bottle mixed in corn grit.
- 10,000 ct. – 4 oz. bottle mixed in corn grit.
Shelf Life: Use within 18 hours of receipt.
Life Cycle: Females lay up to 54 eggs over their lifespan concentrating egg laying on spider mite webbing and in high density pest populations. Eggs hatch within 1-4days, depending on environmental conditions, and mature through five life stages: egg, larvae, protnymph, deutonymph and adult. Maturation to adulthood takes up to 8 days and adults live for another 30 days or so.
