I heard that Vicks vapor rub wards off bugs like misquitos. Just putting a little bit on your kneck or wrists is supposed to be better than bug spray and less hazardous. Has anyone heard this or tried it?
Sounds to me like you want to feed the bugs...
There are many rumors of various substances repelling bugs. Many of the reports are untrue or of substances which are not as effective as DEET.
DEET is provern effective and safe if used properly:

Note comments on safety near the end.
Excerpt:
"Despite the substantial attention paid by the lay press every year to the safety of DEET, this repellent has been subjected to more scientific and toxicologic scrutiny than any other repellent substance. The extensive accumulated toxicologic data on DEET have been reviewed elsewhere. DEET has a remarkable safety profile after 40 years of use and nearly 8 billion human applications. Fewer than 50 cases of serious toxic effects have been documented in the medical literature since 1960, and three quarters of them resolved without sequelae. Many of these cases of toxic effects involved long-term, heavy, frequent, or whole-body application of DEET. No correlation has been found between the concentration of DEET used and the risk of toxic effects. As part of the Reregistration Eligibility Decision on DEET, released in 1998, the Environmental Protection Agency reviewed the accumulated data on the toxicity of DEET and concluded that "normal use of DEET does not present a health concern to the general U.S. population." When applied with common sense, DEET-based repellents can be expected to provide a safe as well as a long-lasting repellent effect. Until a better repellent becomes available, DEET-based repellents remain the gold standard of protection under circumstances in which it is crucial to be protected against arthropod bites that might transmit disease."
DEET may be applied to skin and/or clothing. It is a solvent and, particularly in high concentrations, can damage some plastics.
Picardin-based repellents have just been introduced to the US market. Performance appears to be similar to DEET of a similar concentration.
Permetherin is a contact insecticide which is applied to clothing. (It is not effective on skin.) It is best applied at home and lasts 2 weeks or so.
I use permetherin on my clothing and 20-30% DEET on skin if needed.
