Cockroaches in Benijofar

There has been a plague of cockroaches in the Calle Vicente Blasco Ibanez area of Benijofar, the reason is that when the road was resurfaced 18 months ago ,the manholes were covered, normally the pest control people put stuff down the manholes to control the infestations but have been unable to do so, and with the wet and warm weather the cockroaches have spread into properties in the area. Once they get into this environment they are very difficult to exterminate. The manholes are now opened and poison put down.
