Ants in the newly built rental property

[Suvarna Joshi]

I have a rental house in Texas that I bought new from the builder and is still under 1 year structural warranty. The tenants recently called to report the ant problem in the master bathroom. Apparently the ants are coming through the unsealed areas in the bathroom where builder did a poor job of caulking and sealing the gap under trims. My question is- should I just open a repair request with builder and get those areas caulked or do I need to get the detail pest inspection done for possible structural ant infestation? The ants seem to be more in number than I would expect considering that there is regularly scheduled pest control service for the house, so not sure if there is a deeper problem here. Any suggestions are much appreciated.
