As Gauteng residents experience flash flooding due to heavy rainfall, Rentokil warns of the impact residual standing water can have on fly and mosquito infestations.

Heavy rains in Gauteng this week have seen numerous car accidents, flooding on several roads and reports of lightning strikes. At the time of writing, provincial government has activated a disaster management centre to investigate the trail of destruction and continue with search operations.

As the waters recede over the next days and weeks, residents are going to be faced with another issue; that of residual standing water. Standing water may not seem like a huge concern in light of the damage caused by the flooding, but it has the potential to cause a significant longer-term problem; that of an increase in the fly and mosquito population.

Both flies and mosquitoes lay their eggs in standing water, and hot weather – such as Gauteng residents generally experience between October and March- increases the probability of a large scale infestation because larvae hatch, mature and reproduce at a much faster rate in the heat. Under optimal conditions, fly larvae can mature into adults in as little as four days!

This is problematic because both mosquitoes and flies are known to spread disease. Flies carry diseases like malaria, dysentery, gastro-enteritis, typhoid fever, cholera, conjunctivitis, tuberculosis and diarrhoea. They also cause parasitic tapeworms in poultry and horses. Mosquitoes are just as bad, carrying infectious diseases from several different classes of microorganisms, including viruses and parasites. Mosquito-borne illnesses include malaria, West Nile virus, elephantiasis, dengue fever, yellow fever and zika virus.

Whilst there are many DIY options for flies and mosquitoes, most of them don’t fully resolve the problem. DIY solutions may be able to get rid of adult flies and mosquitoes, but the larvae and eggs are often left untouched, resulting in another infestation arising.

Mosquito and fly prevention tips:

If you are keen on getting rid of flies and mosquitoes yourself, there a couple of prevention tips you can enlist which have a proven track record of reducing the presence of both flies and mosquitoes. The most important of these is to eliminate any source of standing water around your home, so that you break the breeding cycle.

Remove any standing water from your garden; empty pots, buckets etc where rainwater may have accumulated
If you have a garden pond, think about adding some goldfish as they will eat fly and mosquito larvae.
Water tanks or jojo’s should be covered with a well- fitting lid.
Change the water in your pets dishes regularly
Maintain your gutter by removing old leaves which can cause blockages and the risk of standing water
Keep grass and weeds trimmed and under control
Inside, keep the air circulated using fans
Install fine mesh screens on doors and windows
