It may be cheaper than off but it's unlikely it works as well, especially if it's off with an higher content in Deet. As much as Deet is not a very healthy product and you don't want to overuse it, nothing is as efficient against moskitoes that you can spray on yourself. Yes there are natural and other products that works, but not as good as a high Deet concentration product. Where I live now and where I have traveled over the years is full of moskitoes and I have tried litterally every product available, every home made but nothing has been as efficient as Deet. Where I live is actually a testing ground for several products against moskitoes.

And it makes sense you will find moskitoes under tables as it would be away from the sun and possibly a slightly higher humidity content under a table, especially if covered by a nap.
