Is there a mat bug in the mahjong mat in summer? How to deal with it?

I haven't found this problem after using mahjong seats for many years. However, as far as I know, mat bugs are produced because mats are wet. Small red pimples (similar to those bitten by mosquitoes in the north) will appear all over the body after being bitten, which is extremely itchy.

If you want to get rid of the bugs on the mat, you should first keep the mat clean and dry it often. If there is sunshine, you'd better wipe it with a towel and dry it. Without an environment suitable for the survival of mat worms, mat worms cannot survive. If the weather is always wet, you can put some mothballs or insect repellent on the bed.

Another way is to go to the drugstore to buy a bottle of spray for killing mat insects, treat the mat according to the instructions, then scald it with boiling water and expose it to the sun. This operation is done once a week, and the mat is wiped with a warm towel twice a day before going to bed.
