Pest Control FAQs, answered by experts

DIY treatments exist, but professional extermination is recommended for thorough elimination and prevention.

Professional treatments can be immediate but may require follow-up for complete effectiveness, lasting several weeks.

You can 100% get rid of roaches, but it takes weeks or months of consistent killing effort, meticulous kitchen clean-up, and airtight food storage. Working with a local roach control pro to fight an infestation enhances your DIY efforts to ensure total elimination. A multi-pronged approach with a roach contractor prevents repeat infestations.

Yes, bears can smell through walls if they are close enough. Estimates vary, but experts say bears can smell up to a maximum distance between one and 20 miles. Food inside a house does not attract bears to the degree that food left outside does, though.

Squirrels have a strong sense of smell and can be deterred by various scents they dislike. Effective options include peppermint oil, rosemary, garlic, cinnamon, white vinegar, coffee grounds, and predator urine. Squirrels also have a strong aversion to capsaicin, the compound that makes chili peppers hot, making capsaicin-based repellents a good choice for protecting specific areas like gardens or bird feeders. For a DIY solution, you can create a garlic and vinegar spray and apply it daily. Additionally, placing strong-smelling items like certain soaps or dryer sheets near where squirrels frequent can also be effective.
