For infestations covering large areas, growth regulators are used. When larvae ingest such a substance after it is brought back by worker ants, they die en masse. The eggs laid by a queen ant that has ingested the toxin will not be able to hatch, and the colony eventually dies out.
大面積的區域則採用「生長調節劑」，以干擾火蟻幼蟲的發育，幼蟲吃了工蟻帶回來的藥劑後會死亡，蟻后吃下後生的卵也無法孵化，蟻巢因而走向衰亡。
