### ⭐⭐⭐⭐ Dethlac Insect Laquer
*by T***T on 26 April 2012*

Used for a house infestation of North American ladybirds - seems to kill 'em stone dead judging by the body count. It's not instantaneous but nonetheless effective for all that. It's also effective for quite a few months. A bit pricy to sort out all rooms in the house but a hell of a lot cheaper than getting in private pest control since our local authority don't want to know. It's also been used equally effectively to show ants the way from the world, that is to say ants that invaded our house too. All in all worth the price.
