Frequently Asked Questions

Q: How Do I Stop an Ant Infestation?

Choose the appropriate killer depending on the type of insects, their number, and gathering places (indoors or outdoors.)

Q: How Do You Get Rid of an Ants Nest?

A: The best approach is to use baits with a slow-acting poison. Ants will grab the bait and carry it to their nest and die there. Other ants will eat the dead mates and die too. Thus, using the domino effect, you’ll be able to eliminate the whole colony, including the queen.

Q: Are There Any Poisonous Ants?

A: Ants produce a specific type of venom to defend themselves in the natural environment. Normally, this venom is too weak to kill or cause any serious harm to human. That said, stings of some ant species can cause allergic reactions, which, in turn, result in a fatal outcome.
