When I moved into my apartment in Valencia I saw armies of ants parading on their little, defined routes. I used the clear Terro liquid on cardboard and they were gone promptly. Left the place for two months of travel expecting that I would be overrun on arrival, but they were nowhere in sight. After being here for a few weeks, I started to notice them just a little bit. Finally rolled out the Terro today and they must have made an announcement about the free food because they massed at the chow-down. Actually ate all of the bait I put out, so I replenished and they are still eating. It appears that they are now on crack cocaine as they are running around in just a bit of a frenzy. I just hope they get some back to the queen, and then they will be gone for quite a while, I guess. I love chemistry....I mean...nature!

 

We wipe Malathyon (sp) on the foundation of our house. Be sure to use gloves, it's nasty stuff.
The ants do not re-appear for a couple of months.
The smell is terrible for a few hours but worth the annoyance.
Available at most Agri Vet stores.

 

I believe for low cost Boric acid "Boraxo" mixed with sugar, works the best. But, I have not found it yet in the Philippines. I have been using Terro Liquid Ant Killer. They sell it at Handyman across from Lee Plaza, they didn't have it at Handyman Robinson's Place.
