The Sniper insecticide is very popular in Nigeria. It has been known as the most effective method of driving away insects including mosquitoes, cockroaches and more.
However, on the bottle, it is clearly written that it is meant for outdoor use (on farms or greenhouses) and should be mixed with water to reduce the concentration.
Sniper belongs to the DDVP chemical family, 2,2-dichlorovinyl dimethyl phosphate compound, marketed in Nigeria by a Swiss-Nigerian Chemical Company, as a synthetic organophosporus but many Nigerians have turned it into an indoor insecticide. One can be exposed to the many risks of DDVP by breathing it in, skin absorption, swallowing it, and eye contact.
Center For Disease Control (CDC) , states that the effects of exposure may include irritation of eyes, skin; miosis, eyes pain; rhinorrhea (discharge of thin nasal mucus); headache; chest tightness, wheezing, laryngeal spasm, salivation; cyanosis; anorexia, nausea, vomiting, diarrhea; sweating; muscle fasciculation, paralysis, dizziness, ataxia; convulsions; low blood pressure, cardiac irregularity.
There are lots of insecticides that contain DDVP chemical, but Sniper insecticide still seems to be the most abused and overused; hence the emphasis.
It has been observed that people would rather use Sniper than other well established brands of insecticides because of its supposed effectiveness, the price and their ignorance of the health dangers.
