I had a sudden invasion of ants a few months ago that caused some damage. As others have indicated, move the tarantula to a new container with fresh substrate. But you'll also need to make sure the ants are not going to re-invade. I was able to get poison ant bait traps at a local store, and they worked wonders. I keep a bunch of them on hand now, and have one on each shelf in my arachnid room.Remove the tarantula, and clean the entire terrarium and put in new substrate and put the tarantula back in.
There are thousands of varieties of ants, and only some of them would pay any attention to sugar. While you are fattening up the sugar ants in your back yard, the ones invading your cages (which are not looking for sugar) would continue to invade.Bury a pound of sugar in your backyard. Give the ants something else to annoy.
But she's so subtle about it.....I think BatGirl really hates ants.
Right. Stupid nasty evil demon things. Riding lawn mower or firecrackers are more fun. I swear they just move around the yard and never die. They should have brought the flies to regulate them if they were going to stick us with the damn things. Only way I have ever kept them under control is over and out and instead of wetting down with water use cutters spray to take care of both my most hated pest. All Sketters and fire ants must die. Actually this year they haven't been bad till a few weeks ago. I didn't get one mosquito bite till fall started even with high grass in the back lot.Batgirl lives in fire ant country so has every right to hate ants. We always mess with fire ant mounds when doing field work in the South. It is so much fun to swing a golf club at a fire ant mound to last those buggers and see them go bananas looking for something to bite. If you have ever been stung by a fire ant you would sympathize.
