I just moved in to our new flat which has parquet flooring. This flat has been built for more than 3 years and we are the new occupants in this house. We noticed little black particles on the floor every 2-3 days after we clean up the place and we notice black ants moving around esp. in this room. We called HDB to check whether there was a nest in this room. HDB came and remove the parquet skirting at the side of the wall. True enough, there were 2 camps of ant nests in one of our rooms! Baygone was quickly sprayed at the infested areas. The nests were removed and from that day onwards, we rarely see any ants in our house. Our contractor told us that if there are black ants, you will not see termites. They are enemies. The black ants will eat the termites. Not too sure myself. U can do some research on this. We have to careful when using parquet flooring as it requires maintenance. It looks good but maintenance is key to ensure that we have a comfortable and clean environment to live in. Just a slice of our experience with parquet and ants.
