The STUCK Mosquito Traps are designed to attract female and male mosquitoes to a stagnant water source. They find our traps to be the perfect environment for shelter or to deposit eggs. Our traps are simple, effective and easy-to-use. The trap operates without the use of pesticides, harmful chemicals, or electricity. Simply put, we've created something that mosquitoes are naturally attracted to, so all you have to do is add water and let the trap do the work.
