Herbicides and pesticides are killing frog species worldwide now and have led to the extinction of many species of frogs already around the world

So, if you find frogs trying to live in your hot tub it means that your area isn't so polluted with herbicides and pesticides that it kills all the frogs.

Though I have found frogs when I first moved here in 1999 up to around 2009 or 2010 I haven't seen any here trying to climb into my hot Tub (Jacuzzi spa) since around 2010 which likely means neighbors of mine are spraying things like Roundup which is a weed killer and has killed many people who use it too worldwide because it is similar to Agent Orange which defoliated the DMZ between North and South Viet Nam and is still causing human deformities and mole pregnancies in locals there to this day in Viet Nam.

Also Frogs take in chemicals of all kinds through their skin just like apples and potatoes do too. So, it isn't really good for humans to eat apples or carrots or potatoes that have been sprayed with insecticides or herbicides as a direct result because you cannot wash these off these types of vegetables because they go into the meat of the vegetables.

So, because there is NO barrier between frogs and the chemicals humans use many areas of the world are completely devoid of all frog species and this is also something to think about for people who eat frogs because all the toxins the frogs people eat have taken in through their skin also will concentrate and infect the people who eat these frogs too potentially. 

Conclusion:

So, the lesson here is eat organic potatoes and apples and carrots and maybe don't eat frogs because of the toxins created by humans that they have absorbed into their bodies during their time alive on earth.

The other lesson of course is frogs are likely going to be extinct on earth within 20 to 30 years completely.
