Apartment cockroach & ant infestation

Hi there, I just moved back to Cyprus and staying with my mum. She’s been in this flat for a year and I noticed we have a year-round cockroach and ants infestation. Mainly in the toilets, kitchen & living room. My phone doesn’t work at the moment button WhatsApp is +447783414626. Please could you tell me how much an apartment extermination will cost for an apartment? Thanks! Noelie H
