you probably still did not get a answer u looking for :
but i found how to control them around my house
1: petrol works only for about 6mths and they back in the same hole about 2ltrs i used and a match
2. insecticide i do my own pest control but i still think public should be banned and should be controlled better i buy my chemicals from LANDMARK agg store A. its cheap B. better range.
ok so buy some insecticide eg. group 3B, 3A , 2A so on now remember the group class you used this year to kill the ants coz the following year you need to use another class coz you dont what them to get immuned self educated on that and there's not much info on this so if anyone knows more teach me more apart from the 3hr to find government documents.
ok now you got your $50 1ltrs good shit mix it up like it says 80mls to 5ltrs
get your sprayer spray a nice mist around your houses window paving eves eta.. then pour about 0.5ltrs of milky water into each hole you find then next time you see them do the same but with a different class i did it 2 years in a row damm fire ants are back after 5yrs Perth
btw i redo my house every 6mths to protect from spiders small ants that looking for food scraps cockroaches eta....
