Raccoons are primarily crepuscular and nocturnal, meaning they are most active at dawn, dusk, and throughout the night. While less common, they may come out during the day to find food, especially in warm months or during the spring birthing season (April and May) when caring for their young. Seasonally, raccoons are active year-round and do not truly hibernate. However, during periods of severe cold, they will often remain in their dens for extended periods.

When you spray a roach, the chemicals, usually a mix of neurotoxins like pyrethroids or pyrethrins, start affecting its nervous system almost immediately. It disrupts the roach’s nerve signals, causing paralysis and eventually death. You'll often see the roach twitch, flip over on its back, and stop moving within seconds to minutes.

Common house roaches, typically American cockroaches or Periplaneta americana, usually live for around one year. The male American cockroaches survive for about one year, although the females may live up to 700 days. That’s because the reproductive cycle alone can last around 600 days for this type of cockroach.

Squirrels rely heavily on their sense of smell and are deterred by a variety of scents. Some of the most effective smells for repelling them include peppermint oil, coffee grounds, white vinegar, garlic, cinnamon, rosemary, and predator urine. They also have a strong aversion to capsaicin, the compound that makes chili peppers hot, making capsaicin-based sprays an effective repellent for areas like gardens or bird feeders. For a DIY solution, you can create a spray from garlic and vinegar and apply it daily. Additionally, squirrels dislike strong, fresh scents, so placing items like strong-smelling soaps or dryer sheets in areas they frequent can also help keep them away.
