As temperatures continue to rise due to global warming so does the wasp population. This summer was one of the hottest in recent years and also saw the highest number of wasp infestations recorded by Rentokil in the last five years.

Wasp infestation in Ireland

Rentokil, Ireland’s leading pest control provider, has reported a significant increase (108%) in the number of callouts for wasp infestations during the period of July – August this year when compared to the same period the previous year. Ireland’s record-breaking temperatures this summer saw a steep rise in the number of home and business owners experiencing infestations from these annoying pests. Dr Colm Moore, Area Technical Manager for Rentokil, is today advising the public that it will be October at the earliest before the wasps dissipate for the winter.

As wasps are most aggressive towards the end of summer and beginning of autumn, it is advisable to call in a pest control expert such as Rentokil when dealing with wasp related issues. Rentokil predicts that if we get mild winter and good spring next year, the summer of 2019 will see another surge in wasp numbers.

Dr Moore said: “Wasps are most active in the late summer/autumn months. In Ireland, the Common and German Wasp cause the most annoyance with their distinctive yellow and black body. If you are experiencing high numbers of wasps in your home or garden there is likely to be a nest nearby. Although for the most part, this is not an issue at the beginning of the season, this can sometimes be problematic as mature nests in summer can contain thousands of wasps and the behaviour of the workers changes towards September, when they become more aggressive. To avoid stings and keep you and your family safe, the best course of action is to avoid the nest and consider having it treated. You do not need to have the nest removed in its entirety”.

The top four counties in Ireland that accounted for Rentokil’s callouts for wasps between June and August were:

• Dublin 37%
• Kildare 10%
• Galway 10%
• Mayo 9%

If you are experiencing high numbers of wasps in your home or garden there is likely to be a wasp nest nearby, either on your property, in your garden or very close by.

How to avoid wasp sting

• Dr. Moore offers the following tips and advice to avoid being stung:
• Do not panic – If you find there are wasps nearby keep calm and move slowly away.
• Do not scream, flap your arms or swat them – This will just agitate them and make them more aggressive.
• Avoid strong, sweet smells – Do not use highly perfumed fragrances, shampoos, hair sprays.
• Avoid bright colours – Do not wear bright, bold floral patterns on clothes and bags, which could attract wasps.
• Avoid orchards – Or any soft fruit plants and even uncovered bins, where wasps gather seeking food.
• Avoid open drinks – If drink cans or bottles are left unattended, it may encourage wasps to crawl inside.
• Cover food and drink – Always keep food and drink covered when eating outdoors to deter wasps.
• Stay clean – Ensure children’s hands/faces are cleaned after eating sweet foods/drinks.
• Never leave sugary drinks unattended. Also, always check sugary drinks for wasps before consuming.
