1 00:00:00,560 --> 00:00:03,600 Speaker 1: Welcome to brain Stuff from house Stuff Works dot com 2 00:00:03,600 --> 00:00:08,080 Speaker 1: where smart Happens. Hi Am Marshall Brain with today's question, 3 00:00:08,600 --> 00:00:13,119 Speaker 1: what is in moth balls and is it harmful to people? Clothes? 4 00:00:13,240 --> 00:00:15,680 Speaker 1: Moths can be a real problem in clothes made from 5 00:00:15,760 --> 00:00:19,720 Speaker 1: natural fibers, especially wool. There are two different types of 6 00:00:19,760 --> 00:00:23,240 Speaker 1: moth balls used to combat these moths. In one type, 7 00:00:23,280 --> 00:00:27,480 Speaker 1: the maid ingredient is naphthaline, and in the other it's paradichlorobenzene. 8 00:00:28,040 --> 00:00:31,120 Speaker 1: The idea with both chemicals is to kill moths and 9 00:00:31,240 --> 00:00:36,960 Speaker 1: moth larva with the fumes. Both naphthaline and paradichloro benzene sublimate, 10 00:00:37,159 --> 00:00:41,239 Speaker 1: meaning that they transition straight from solid to gas. The 11 00:00:41,320 --> 00:00:44,479 Speaker 1: gas is a toxin to the maths. For either of 12 00:00:44,520 --> 00:00:47,360 Speaker 1: these chemicals to be effective, they need to be placed 13 00:00:47,400 --> 00:00:50,199 Speaker 1: with the clothing in a sealed container so that the 14 00:00:50,280 --> 00:00:52,800 Speaker 1: fumes can build up and kill the maths. In a 15 00:00:52,880 --> 00:00:56,120 Speaker 1: sealed atmosphere like this, the fumes are not harmful to 16 00:00:56,240 --> 00:00:59,640 Speaker 1: people because they are contained. The main threat would occur 17 00:00:59,720 --> 00:01:04,040 Speaker 1: when opening the containers or from wearing clothes immediately after opening, 18 00:01:04,360 --> 00:01:07,920 Speaker 1: which is especially a problem for infants. A solution is 19 00:01:07,959 --> 00:01:11,080 Speaker 1: to open the containers outside and then let the clothes 20 00:01:11,200 --> 00:01:13,760 Speaker 1: hang in air out for a day or two before wearing. 21 00:01:14,440 --> 00:01:17,240 Speaker 1: We all seem to have that aunt whose entire house 22 00:01:17,280 --> 00:01:20,480 Speaker 1: smells like mothballs, and we've all walked into a public 23 00:01:20,560 --> 00:01:24,679 Speaker 1: restroom where the smell of parodichloral benzine is nearly overpowering. 24 00:01:25,120 --> 00:01:29,559 Speaker 1: Are these fumes healthy? The answer is probably not. Neither 25 00:01:29,640 --> 00:01:32,680 Speaker 1: of these chemicals is particularly good for people to breathe 26 00:01:32,720 --> 00:01:35,880 Speaker 1: on a regular basis. Airing out clothes is a way 27 00:01:35,880 --> 00:01:41,080 Speaker 1: to limit the exposure unless toxic. Alternative is cedar blocks, shavings, 28 00:01:41,160 --> 00:01:44,840 Speaker 1: or oil. The blocks are expensive, but cedar shavings in 29 00:01:44,880 --> 00:01:48,639 Speaker 1: the form of hamster bedding can be really inexpensive. Again, 30 00:01:48,680 --> 00:01:51,200 Speaker 1: the container needs to be closed in order for the 31 00:01:51,240 --> 00:01:54,240 Speaker 1: cedar sent to have any real effect on the moths. 32 00:01:55,400 --> 00:01:58,240 Speaker 1: Do you have any ideas or suggestions for this podcast? 33 00:01:58,680 --> 00:02:01,160 Speaker 1: If so, please send me an e mail at podcast 34 00:02:01,200 --> 00:02:03,760 Speaker 1: at how stuff works dot com.
