Cockroaches & Shared-Wall Migration
German cockroaches (Blattella germanica) thrive in the warmth and moisture behind dishwashers, fridges and renovated cavities. Spraying alone scatters the population through shared brickwork. We run gel baiting programs using rotated actives like indoxacarb and hydramethylnon, targeting the breeding harbourage. For larger Australian cockroaches coming from subfloors and drains, we add a solid residual barrier and seal entry penetrations.
