Because the electrostatic force decreases with range, there exists a net attraction.
A negative object produces the contrary polarization, but again attracts the neutral object.
The same impact occurs for a conductor; since the unlike charges are closer, there exists a net attraction.Neutral objects could be attracted to any charged object.
Insulators are of help for coating wires, or acting as dielectrics in capacitors.
An insulator can have 1020x the resistivity of a steel like copper.
Often times these insulators are colour-coded to create it easy to tell what function the cable inside is serving, see figure 1 for an example.
