SOUTH Korea was the latest country to declare a war on bedbugs following a resurgence in cases.
Authorities fear for the worst after an expert warned Japan may be next.
This year, South Korea witnessed its biggest bedbug outbreak in the past 40 years.
From just nine cases in 2014, the numbers soared to 180 in the past three months alone.
Authorities fear Japan will face the same outbreak following an increase in cases.
Professional bug killers are on the rise amid growing bedbug anxiety in Asia that was triggered by similar infestations in the United States and Europe.
The nocturnal, bloodsucking creatures usually hide in cracks and gaps in furniture during the day and crawl out of their hiding places at night to feed on the blood of humans and pets.
One female bedbug can produce hundreds of eggs which means populations can easily explode.
Local officials are also concerned the bedbugs have become more resilient chemicals compared to previous infestations.
