My best friend outdoors

I don't know why do I have so many mosquito repellents...from Mexico! I took my outdoors kit  with me today and it was so heavy! I went through it and found 5 mosquito repellents and 6 sunblock bottles. It was hard to figure out how old they were, since they have no expiration date! But there's no way I'm going to throw them away! Why did I get so many? I guess I'll have to try them at the risk of being bitten by mosquito if any of these repellents doesn't work. It will be a fun summer or a miserable one.
