Crematogaster scutellaris utilizes its toxin as a method to subdue prey. The toxin is delivered through a bite via specialized mouthparts. While primarily affecting smaller organisms, the intensity of the toxicity can range from mild irritation to severe reactions. For example, humans and domestic animals such as dogs and cats may experience discomfort or allergic reactions. The adult stage of crematogaster scutellaris is responsible for the secretion of the venom that causes these adverse effects.

Crematogaster scutellaris, typically a non-aggressive species, do not characteristically bite humans. Instances of this behavior are uncommon unless the ants feel threatened or their nest is disturbed, leading to a defense response. The bites are usually mild with minimal immediate consequences.

Crematogaster scutellaris can create trouble for humans due to their nesting and feeding behaviors. When they establish their colonies within homes or buildings, they can cause structural damage by burrowing into wood or insulation. Electrical systems may also be compromised as crematogaster scutellaris may chew through wiring, causing safety hazards and requiring costly repairs.

To prevent issues caused by crematogaster scutellaris, it's crucial to maintain structural integrity by sealing cracks and crevices in buildings. Regularly inspect and repair any damaged wood or insulation. Manage moisture levels, as crematogaster scutellaris are attracted to damp conditions. Also, ensure proper housekeeping to deter crematogaster scutellaris from seeking food inside homes.

After troubles with crematogaster scutellaris occur, start by identifying and removing their food sources to discourage further infestation. Use physical barriers such as airtight containers for food storage and seal entry points. Employ environmental controls such as reducing moisture in infested areas. During recovery, keep living spaces clean and dry, and routinely check for signs of re-infestation to prevent future issues.

Crematogaster scutellaris is considered a structural pest due to its potential to inhabit and damage buildings. In their development as larvae and adults, they can compromise wooden structures and cabling. Damages can range from mild to severe, causing issues like weakened structural integrity and electrical faults. People may face repair expenses and safety hazards due to their destructive behavior.
