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.

The label on H24 says "Dietal toluamida 20%." I've yet to meet a mosquito that buzzed: "Hah! Only 20%? No problemo."

Actually, one of the difficulties dealing with Mexican mosquitoes is that they're so tiny, you can't hear them. REAL mosquitoes of the, say, Winnipeg variety....the size of small hummingbirds.....can be heard 10 meters away.

My problem, other than those occasions when I'm under the table, are the jejenes/sandfleas/zancudos/noseeums....whatever they are.... that occupy a narrow band of territory of the beach at Playa Larga, between the restaurants and the shore. They're the closest thing I've seen to our voracious Canadian black flies - and H24 works just fine for me.

Walmart's Great Value 100 ml pump spray, at $5, says "Guarantee: DEET plus related active toluamides.....30%." It works well too, at half the cost of over-priced OFF.
