Not exactly. The only difference is the term ‘insect repellent’ is a more general term, meaning that the product not only repels mosquitoes but insects in general. Mosquito repellents deal with mosquitoes only. Insect repellents can be used even during the day and on clothing, but mosquito repellents are only to be used at night when mosquitoes are most active. But this can vary depending on your country. Some countries have a larger number of mosquitoes than others.
