The answer is probably yes, but ivermectim is not available for human use in many places. I know of trials in which lice have been killed off with oral ivermectin, but lice blood feed many times so not sure if a single blood feed by a mosquito would kill it.

There is a safe dose - consult medical recommendations - its used a lot to control internal parasites in people and animals

You're correct - fogging is 50% effective against Aedes ageypti so basically useless. Local authorities use it to look like they are doing something. I wouldnt put ivermectim in water sources to prevent breeding - Bacillus thuringiensis or sphaericus or IGRs are the preferred method for treating water. Besides you would go broke...

I would be very careful. (a) Widespread use is likely to produce strains resistance to avermectins in many species. (b) Many avermectins are highly toxic to many aquatic species including some fish.(c) The classic way to produce resistance to any pharmaceutical is to under dose and use widely. In short to be used widely in the environment would need very careful planning and to be frank I doubt it is possible with that class of drug. Sorry to disappoint you

Aside from the fact that Ivermectin is not approved for human use in the US, part of prevention involves wearing long sleeves and using insecticides like DEET topically.  So, taking Ivermectin and then wearing long sleeves and using insecticides like DEET sort of cancel each other out.  I favor trying to eradicate the mosquitos by reducing stagnant water breeding grounds.  Unfortunately, I do not believe there is an easy and totally effective preventative approach.  Very major public health issue.

I thank all those who responded to my question. However, please note that my focus was only on the use of Ivermectin with animals like dogs. The idea is that research could estimate the number of mosquito bites a street dog gets in a day and whether safe doses of Ivermectin given to dogs kills the mosquitos that bite them. 

On another matter, I do agree that denying stagnant water collections to mosquitos for laying eggs is a good idea. Unfortunately, in many countries of the world, learning to do this might take two generations! 

I had earlier looked up the status of Ivermectin as medication for humans. I revisited this question and found that its use as an anthelmintic has been approved in India and it is produced as a generic by a few dozen companies. Visit

However, I reiterate that the focus of the question I had posted on ResearchGate was only the possible utility of giving it to street dogs in safe doses, to kill mosquitos without harming the dogs.

Saul, that is a valuable answer giving an important reference. Thanks.
