Pros:
It is (mostly) based on pyrethrine spray which kills the
insects rapidly.
It not poisonous to other animals.
It uses synthetic, natural spray which is safe to use because
it breaks down within 10 minutes.
Te technique can reach tall forests.
It can be used in closed spaces ( greenhouses, basements
etc).
Cons:
It requires windless circumstances ( which is mostly at
nights).
Breathing fog may cause respiratory and throat irritation to

Answer:
The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.
Explanation:
The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry anywhere.
Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.
Thus, the worst option are- nuclear, hydroelectric, combustion and fuel burning energy source.
