Any recommendations or suggestions please? I was quoted THB 9000+ for a year. I think I might take this on for a year before having the floors ripped out and replaced with laminate.

I need something that kills the colony as it's a longtime issue. I fell off monthly blasting with orange Chaindrite aerosol last year for a few months and noticed bad activity yesterday. I forgot my usual mask and goggles and had angina last night into this morning

Thanks in advance. 

different company but assuming you check what they use the companies are pretty reliable, I use rentokil but the chemical for termite - which also works on ants and cockroaches- is that same as for the cheaper companies and is pretty succesful, it is the hygiene standars of the neighbours that is the real problem
