Organic control that clears spider mites without stressing plants
Dr Schimmel Spider Mite Killer is a 100% organic treatment that prevents and eliminates spider mite infestations without harming your plants. Suitable for hydroponics, coco and soil, it can be used across the entire cycle, from young seedlings right through to the final stages of flowering. The gentle organic formula targets mites quickly while staying safe in indoor growing environments, so you can protect plant health without reaching for harsh chemicals.
Key Benefits
- 100% organic spider mite treatment, safe for indoor grows
- Controls and prevents infestations, working as both a preventative and an active treatment
- Full life-cycle use from seedling to late flowering
- No harsh chemicals, protecting foliage and plant health
- Media flexible, suitable for hydroponics, coco and soil
- Easy to prepare and apply as a foliar spray
Spotting speckled leaves and webbing?
Spider mites feed on plant sap, causing speckled leaves, reduced nutrient uptake, stunted vegetative growth and lower yields if left untreated, with heavy infestations bringing webbing, leaf damage and poor flower development. Dr Schimmel Spider Mite Killer starts working immediately after application, clearing mites while protecting healthy foliage and keeping growth vigorous. Because it is organic it can be used even in late flowering, though direct spraying onto flowers should be avoided to limit excess moisture.
How to Use
- Mix all three supplied components together before dilution, as they work as a complete treatment
- Dilute at 25ml per 3 litres of warm water, or the equivalent ratio for larger volumes
- Spray the whole plant thoroughly, paying particular attention to the undersides of leaves where mites live
- Apply just before lights-off or during the evening to reduce leaf stress
- Use at first sign of mites, or preventatively where infestation risk is high
- Late flowering: avoid spraying directly onto developing flowers to limit mould risk
- Repeat as needed and monitor plants regularly for signs of reinfestation
