"In Time You Will Become Aware That It Works"

First Lady Boss Fancy ordered Harris Famous Roach %26 Silverfish Killer Tablets, 6 oz. on May 24, 2025. The product was delivered on May 25, 2025. "The Story" On May 16, 2025, [Friday] a cockroach was spotted behind the toilet. Bugs are a no, no! By May 17, 2025, spotted in the office ceiling. Then, another one in the bathroom ceiling. Another one in the hallway. On its back on the kitchen floor. This is when the family noticed the poison had started serving its purpose. After these come crosses, as of June 23, 2025 [Monday] no more have been spotted. Although it took research to find this particular product, thank you, Harris. If you have patience, I recommend If not, I do not. Patience is necessary when working with these invaders. With appreciation,

Doesn't really work

I've learned to only use professional products for roach issues. Advion and gentrol point source is what my exterminator uses, and I ended up buying the latter myself after his recommendation. These natural do it yourself products are useless.
