I moved into a newly renovated place and unbeknownst to me, my downstairs neighbors had a roach problem (rental office refused pest control service inside of the residence! Crazy right!) Listen…I was researching and found this product from Pest control professionals in Florida that swear by this stuff! I used two packets in my sprayer with hot water, shook for five minutes and sprayed every area they recommended (behind fridge, behind and under stove, behind dishwasher and in every corner of the place). Within a week every bug that had been in hiding came out extinguished! I HAVEN'T SEEN A SINGLE INSECT in over two weeks!! I am definitely spraying this solution every 3 months. I even sprayed my sister's apartment! This stuff is THE TRUTH! It is worth every single penny.
