Life Cycle of Ghost ant
Egg Eggs of ghost ant are typically oval and minute. They lack distinct features and are laid in sheltered environments. During this stage, the insect is immobile and vulnerable, relying on the environment and parental care for development.
Larva The larva of ghost ant emerges as a legless, grub-like organism, distinctly different from the adult. Larvae primarily focus on feeding and growth. They exhibit molting, where they shed their skin multiple times as they increase in size.
Pupal The pupa represents a transitional stage where ghost ant is encased in a protective cocoon. It is immobile and undergoes significant internal changes, rearranging its body structure to form adult features.
Adult Emerging from the pupa, the adult ghost ant displays a complex exoskeleton, wings, and reproductive organs. The coloration is more vibrant and distinctive, reflecting their mature state. The adults are highly mobile, tasked with reproduction and colony maintenance.

Habitat Preferences of Ghost ant Through Different Life Stages
The eggs of ghost ant are generally located in concealed areas within nests built in soil, under stones, or inside wood. Larvae and pupae are found in similar environments, often in the deeper, protected chambers of the nest where moisture and temperature are regulated. For adult ghost ant, a researcher would search for them in a variety of habitats ranging from kitchens, pantries, and other indoor spaces, to outdoor areas like gardens, under rocks, or around foliage where they seek food and water. Regardless of the development stage, individuals seeking ghost ant will likely have to carefully examine small crevices and protected spaces while maintaining a keen eye for their trails.

How and Where Can You Find Ghost ant at Different Life Stages
Egg Ghost ant eggs are tiny and typically located in the concealed nests. To find them, one might need to locate ghost ant trails and follow them back to the nest.
Larva Ghost ant larvae are found in the nests under the care of adult workers. Identifying the species' nests, often near moisture and food sources, is key to observing larvae.
Pupal During the pupal stage, ghost ant can be found within the nest, sometimes in a cocoon or bare, depending on the species. Gently excavating nests in rotten wood or under stones may reveal pupae.
Adult Ghost ant adults can be found on foraging trails, around food sources, or in their nest. Observing foraging trails during peak activity times can lead to the discovery of the adults and the nest.

Put the ant food near the gathering point of ants, such as under the kitchen counter or under the window sill. This tip can gradually reduce the number of ants. Pay attention to moisture-proof storage. Spray it to the dried place to avoid losing its effectiveness. During this period, avoid cleaning the path that ants pass.

Toxic to Animals

Ghost ant possesses a mild toxicity that primarily affects creatures through stinging. In humans, the sting can cause itchiness and localized pain, whereas pets such as dogs and cats might experience similar discomfort. Other smaller insects can be adversely affected by its venom, which has evolved as a defense and predation mechanism. Adults of ghost ant are known to display this toxic behavior, ensuring their survival and facilitating their feeding habits.
