Many customers tell us about this method. Boric acid with sugar or condensed milk. It is true that this method has been effective for quite some time. The cockroach is attracted to the sugar and when it ingests the product it is poisoned.
However, it should be clarified that this method would eliminate an entire colony only under certain circumstances. One of them is when the level of the pest is relatively low, since in the case of a high level of affection, the cockroaches end up rejecting the ingestion of sugar contained in condensed milk. We recommend much better the use of gel for cockroaches for domestic use. It does not disperse the cockroaches, they consume it and move it to the nest.
