Whats the solution for ants in VN

@Dannyroc3

Leaving a piece of cinnamon will attract the ants. It's a trick often used in Mediterranean countries. Best of luck!

Killing ants is easy - any bug murdering can will do nicely.

Killing the nests can be hard work. I used to kill them by pouring slightly soapy water down the holes, but that only works on the ground floor, and only until a new colony starts up.

@Dannyroc3

Ants dislike some strong smells. Try making a spray with spearmint or peppermint oil. Irish Spring and coast deodorant soap grated like cheese and spread in their tracks is also supposed to work  And I’ve heard that chili peppers work too. Try one of these and if it doesn’t work try another. Banana smashed up with Boric Acid might be another option. 

@drutter

Your ideas are better than the cinnamon. In fact the cinnamon should be the best one, but the Vietnamese cinnamon is a bit bitter

@ajairon

I hope one, or more, of them work. I’m happy to be of assistance.

@drutter

I will try the banana. I had some pancake syrup and thought they would like that but they showed little interest.

In the US, I found ants don't like baby powder but they will just avoid it and take another course. The boric acid w/ sugar takes a few days for them to carry it home and die but after trying a number of dedicated products, that seemed to really work because the spray just kills the ones you see and will repell new ones for a short time.

The boric acid worked so good I placed it around the outside as well.

I had an ant problem when I was living up in Thai Nguyen.

What did an excellent job for me was using a chalk-like stick, called "phấn diệt kiến". Lasts about 2 months per application.

You trace a line where the ants enter an area. I traced around all the doors and windows, and also any suspect plumbing entry/exit points and electrical outlets.

It worked very, very well. The locals swear by it.

(wear gloves when you handle it!)

Soapy water reminds me of my Grandmother, who told me to pour boiling water on the hole or nest.  She was probably

dealing with fire ant nests.

@Dannyroc3

You might also try the product Aidan mentioned, recommend by the locals. The locals would know what works best for any given pest in their area.

As you have already stated, what worked back home, may not work as well here.
