  • Small black ants cause no damage, but large black ants do

Small black ants are harmless. Even though they have mandibles and stringer, their effect at home is not always noticeable. The large black ants cause serious problems at home because they burrow into wooden elements, causing structural damage. The natural habitat for black ants is outdoors, but they make their way inside while foraging for water and food.

  • Black ants are seasonal

Generally, ant swarming spikes during mid-summer. You will often notice large and small black ant problems in the house between June to August. Once outside is warm during spring and summer, they find their way indoors.

  • Black ants are social insects

They have an organized communication system between the queen, king, and workers. The food they share is their primary means of communication. Using repellents on them may scatter their communication trail but doesn’t kill them. Professionals know how they communicate and can trail their activity to their colony, which they need to destroy.

  • You can follow their trail and locate their source

Black ants usually follow a trail to travel between their food source and their colony. The trail will help you discover their colony when you want to eradicate them. Following the trail may be difficult, so you should reach out to professionals.

Black ants live outside in wooden posts, rotten logs and stumps, and decaying decking. Indoors, you will find them around leaking sinks, damaged wood, roof leaks, and wet frames.
