Missing Corn Snake

Question
i have had 2 corn snakes for about 4 months now. i have lost them in the house before but they always show up within a week. however this snake has been missing for about 2 weeks and hasn't fed for about a month. i am getting rather concerned about how long the snake will last without food and do you have any good tips to find him as i have searched all dark and warm places.
many thanks

Answer
Lasting without food is no problem that snake could go 3 or 4 months easily without food.  Water is a bigger issue and probably a good start to looking for the snake.   Look early int he mornings anywhere there may be a source of water and you'll be likely to find it if it hasn't already left the house.  Also the air conditioning ducts are a good place to look.
