Dichlorobenzene refers to three different compounds, all three consist of two chloro groups attached to a benzene ring. The differences arise from the different orientations around the ring the two chloro groups can attach to the benzene. The compounds are:
* 1,2-Dichlorobenzene or ortho-dichlorobenzene * 1,3-Dichlorobenzene or meta-dichlorobenzene * 1,4-Dichlorobenzene or para-dichlorobenzene
Ortho-dichlorobenzene
It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals. In terms of niche applications, it is a versatile, nonflammable, high-boiling solvent. It is an insecticide for termites and locust borers. It is also used in softening and removing carbon-based contamination on metal surfaces.
Meta-dichlorobenzene
This finds no current uses, other than being isomeric contaminants in either chemicals.
Para-dichlorobenzene
It is used to control moths, moulds, and mildew. It finds use as a disinfectant in waste containers and restrooms and is the characteristic smell associated with urinal cakes. It also act as a precursor to other chemicals. The chlorides on para-dichlorobenzene can be substituted with oxygen, amine, and sulfide groups. In a growing application, it is the precursor to the high performance polymer poly(p-phenylene sulfide).
Regardless of the isomer dichlorobenzene will have 12 atoms in total: 6 carbon, 4 hydrogen, and 2 chlorine.

It is polar not ionic no metal present.
due to electronegativity
Any substance that contains poisons or harmful chemicals can be toxic to breathe or to intake. Some of which include household cleaners and products. Examples: p-dichlorobenzene (air fresheners, pesticides), ammonia, bleaches, oils, etc.
Dichlorobenzene
It is a covalent compound.
C6H4Cl2
Regardless of the isomer dichlorobenzene will have 12 atoms in total: 6 carbon, 4 hydrogen, and 2 chlorine.
Frequently used is 1,4-dichlorobenzene.
The bonds are covalent.

From the Wikipedia article on mothballs, "Older mothballs consisted primarily of naphthalene, but due to naphthalene's flammability, modern mothballs instead use 1,4-dichlorobenzene (also called para-dichlorobenzene, p-dichlorobenzene, or PDB)."
Napthalene dissolves anything nonpolar with only dispersion forces. p-dichlorobenzene is not polar because it's symmetrically polarized.
