Rodents, wasps and ants top the list of the most common pests in Ireland.
The list comes from Rentokill, Ireland's leading pest control provider, who revealed that almost a third of their callouts in 2021 were to deal with rodents.
In total, 31% of all pest callouts were rodent-related, with wasps (13%) and garden ants (5%) also causing issues.
Dublin was the county which accounted for the most callouts this year, accounting for 42% of all callouts.
Cork (12%), Kildare (6%) Galway (5%) and Limerick (4%) round out the rest of the top five counties that were most affected by pests in 2021.
Rentokill say the changing public health guidelines throughout the year, as the country went through different waves of the pandemic resulted in conditions for pests to adapt and live in.
As lockdown restrictions were lifted throughout the summer and with improved weather, people began to interact more outdoors which resulted in increased activity of pests at that time.
They also believe that 2022 will be "just as busy" - with bed bugs being associated with increased travel.
Richard Faulkner, Advanced Technical Field Consultant for Rentokil said: "Pests have thrived during the lockdown measures of 2021 in environments such as vacant buildings which offered the perfect shelter for rodents and other pests.
"As those measures were eased in the summer and people socialised more, especially outdoors, this saw greater interaction between the public and pests, particularly wasps who would have benefitted greatly from outdoor socialising.
"With the relaxation of public health restrictions, it is expected that an increase in pest activity will occur and as we get back to normal levels of social activity there will be greater opportunities for them.
"Smart pest control measures which utilise expertise and technology are the best option to combat any pest issue that people encounter.”
