Hard Scale Insect Killer -

Treat hard scale insects indoors with our Hard Scale Killer and let the both the larvae and adult predatory beetles of Chilocorus nigritus loose on this common greenhouse and conservatory pest. The greedy black ladybird-like beetles (use 3-5 per plant) are effective during longer days (March to October) and operate at temperatures in excess of 18ºC so are ideally suited to the warm conditions much loved by hard scale insects. The larvae are best suited to individual plant treatments and the adults will return excellent clear-up rates when applied to multiple plants during severe infestations. The adults are not effective in the winter as they need sunlight to be active so aim to supplement your biological control by using instead of the Hard Scale Insect Killer between October and March. Hard Scale Insect Killer is available in three pack sizes; 25 adults 25 larvae or 10 larvae. Please Note: this item will be despatched at the optimum time for application which will now be from March 2011. This live product is despatched to UK addresses only!
