Im not sure what type of creature it is but if you want to get rid of it do a full water change. Thats really the only way to get rid of unwanted creatures. Take out all the fish, snails shrimp anything you want to keep and thoroughly wash all the gravel/ sand plants and anything you think they could be hiding on or have layed eggs on. Then put it all together again and fill it up. Dont forget to put in your water conditioner to get rid of the harsh chemicals in tap water. If they survive that then ...well i dono :P

I found one last year and it came out after almost 9 months. Don't give up yet ! Make sure the temperature in your house or the room you have them in is not too cold. it could influence the length of pupa stage

Hello eveyone! I was wondering if there was a place I could order the Hummingbird Moths from to release in my yard? I have one green tomato horn worm, that ate a green tomato the size of a golf ball in one day, but I would really like to see more of these huge moths out and about. Thanks, Lauren www.starbengal.net

Don't freak out yet. They're not that bad sometimes. :) Are you in the country or city? In the city it can be harder. Every time you open up a wall or hole, put in large amounts of boric acid. You can puff it through cracks with a turkey baster. They get their toes in it and wash themselves and get sick and die. It lasts forever and if you put it behind walls and under cabinets, nobody who is supposed to be in your house will get into it. Also, check with your local ag extension service--they may have suggestions for your particular area. And remember, those egg cases could be 50 years old and the cockroaches may be long gone.
