Pairs well with
Kill-A-Mite by Nulife Technologies is a concentrated foliar miticide built around 18g/L abamectin — the registered active ingredient Australian growers reach for when two-spotted mite, tomato russet mite, or tobacco leafminer have broken through their preventative program. One 100mL bottle makes roughly 110 to 170 litres of finished spray at the label rate of 0.6 to 0.9 mL per litre. Maximum two applications per crop, 28 days apart, 3-day withholding. This is not an organic option — it's a registered pesticide for when prevention hasn't held the line.
Specifications
- Abamectin is a Group 6 active. Don't spray it more than twice per crop, and don't rely on it alone cycle after cycle — mites develop resistance fast.
- Rotate with a different mode of action between crops (neem, horticultural oils, potassium soap) to keep it working long-term.
- Spray when mite counts hit 5 to 6 per compound leaf at the higher rate. Spraying too early, too often, or under-dosing all accelerate resistance.
- Apply out of direct sun and with grow lights off — wet leaves under hot light burn, and abamectin breaks down faster in UV.
- Full PPE is not optional: gloves, long sleeves, eye protection, and a P2 respirator.
How to Apply
Pairs Well With
Build a rotation. Between Kill-A-Mite sprays, alternate with a different mode of action — neem oil, horticultural oils, or biologicals — to protect long-term efficacy.
Environmental MonitorsTrack temperature and humidity. Mites explode below 50% RH and above 27°C — a monitor catches the conditions that invite them in before you see damage.
Clip Fans & Air CirculationMove air through the canopy. Strong circulation disrupts mite webbing, slows colony growth, and keeps leaf surfaces dry enough that predators and beneficials can't establish.
Frequently Asked Questions
Is Kill-A-Mite safe to use in a grow tent?
Yes, when applied correctly. Kill-A-Mite is a registered pesticide — use full PPE (gloves, long sleeves, eye protection, P2 respirator), ventilate the tent well after spraying, and never apply with hot lights on. Observe the 3-day withholding period before harvesting anything edible.
Can I spray Kill-A-Mite on flowering plants?
Yes, up to 3 days before harvest (the label withholding period). That said, most growers avoid spraying anything past week 3 of flower because residue and trichome damage become real concerns. Treat mite issues early in veg wherever possible — prevention is cheaper than recovery.
How many times can I spray per crop?
Maximum 2 applications per crop, spaced at least 28 days apart. This is both a label condition and a resistance management rule — exceeding it risks breeding abamectin-resistant mites that nothing in the same chemical group will kill later.
Is Kill-A-Mite organic or certified for organic growing?
No. It contains 18g/L abamectin, a synthetic registered miticide/insecticide. It is not suitable for certified organic operations. If you need an organic route, look at neem oil, predatory mites like Phytoseiulus persimilis, or potassium soap sprays — all effective when used early and consistently.
Will Kill-A-Mite harm beneficial insects or predatory mites?
Yes. Abamectin is non-selective and toxic to predatory mites, bees, and other beneficials. Don't spray flowering plants that bees visit outdoors, and if you're running biological pest control with predators, Kill-A-Mite will wipe them out. Use it when biologicals have failed — not alongside them.
How long does a 100mL bottle last?
A full 100mL bottle makes 110 to 170 litres of finished spray depending on dose rate (0.6 to 0.9 mL per litre). For most home and small commercial growers, one bottle covers several crop cycles comfortably — particularly given the 2-sprays-per-crop maximum.
Can I use Kill-A-Mite as a root drench for fungus gnats?
No. Older label versions of this product included a drench use pattern, but the current Nulife label is foliar spray only for the registered pests listed (two-spotted mite, tomato russet mite, tobacco leafminer). For fungus gnats, use a product specifically registered for that purpose — beneficial nematodes, BTI, or yellow sticky traps are all effective.
