Pharaoh ants use a positive feedback system of foraging. Each morning, scouts will search for food. When one finds it, it will immediately return to the nest. This causes several ants to follow the successful scout's trail back to the food source. Soon, a large group will be upon the food.
Borate-sucrose water baits are toxic to Argentine ants, when the bait is 25% water, with 0.5–1.0% boric acid or borate salts. [52] [53] In spring, during a colony's growth phase, protein based baits may be more effective due to much higher demand from the egg-laying queens. [54]
Borax is also easily converted to boric acid and other borates, which have many applications. Its reaction with hydrochloric acid to form boric acid is: Na 2 B 4 O 7 ·10H 2 O + 2 HCl → 4 H 3 BO 3 + 2 NaCl + 5 H 2 O. Borax is sufficiently stable to find use as a primary standard for acid-base titrimetry. [17]: p.316
Poisoned bait containing hydramethylnon or fipronil, and boric acid powder is effective on adults. [84] Baits with egg killers are also quite effective at reducing the cockroach population. Alternatively, insecticides containing deltamethrin or pyrethrin are very effective. [84]
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
