Using insecticides safely

Dr. Douglas Street, Contributor

There are some insects that pose a nuisance, or even a danger, to us. We, therefore, have strong motivation to control their numbers. We usually do this by poisoning them. Improper use of these poisons can also poison us if we misuse them.

Children and the elderly are at particular risk of poisoning by insecticides. The dangers of insecticides may be unknown or underestimated by these vulnerable persons. Persons may be exposed to the hazards of insecticides in various ways. Insecticide sprays must be used in properly ventilated areas and persons should not remain in areas that are sprayed.

They may also mistake them for a food or drink, especially if stored in food or drink containers. In addition, the smaller bodies and the incomplete development of children and the deteriorating metabolism of the elderly make them more susceptible to the hazardous effects of the insecticide.

Before using insecticides, make sure that you are aware of the proper procedures. Make sure they are stored in appropriate containers and kept locked away from vulnerable persons. Also, do not overuse the chemical as the excess may put those around in danger, and get the minimum amount required for the application for which it is being used so as to minimise the amount left over.

After usage, it may be necessary to clean the surfaces exposed to the insecticide, especially those to which children will be exposed.

Food should not be exposed to insecticides.

Skin exposure may cause irritation and redness, while inhalation may cause coughing, shortness of breath, and wheezing. Ingestion may cause irritation. An unpleasant odour may be emitted from the mouth or nose. It may also cause vomiting, drowsiness, or even loss of consciousness.

If insecticide poisoning is suspected, drink plenty of water or milk, or ingest activated charcoal. Vomiting should not be induced as this may cause harm. Then seek medical attention as soon as possible.
