What is considered a spider infestation?

• <div><p>A spider infestation happens when an unusually high and problematic presence of spiders occurs in a home to the point it becomes disruptive or poses a significant nuisance. If you notice an increase in spider sightings, numerous webs throughout the home, or see multiple spiders daily, it's likely you have an infestation. In cases where the <a href="https://www.angi.com/articles/types-of-spiders.htm">types of spiders</a> seen are venomous or medically significant species are present, the number of spiders is insignificant and would require pest control measures. On average, <a href="https://www.angi.com/articles/how-much-does-pest-control-service-cost.htm">pest control costs</a> between <b>$300 to $550 </b>for one-time service.</p></div>

Q: Where do scorpions live in homes?

• <div><p>In a house, scorpions tend to live in crawl spaces, attics, in the nooks and crannies of closets and furniture, gaps under doors/windows, and cracks in your foundation. Outside your home, scorpions like to inhabit shady spaces, such as beneath trees. </p></div>

Q: How effective are natural mice deterrents?

• <div><p><a href="https://www.angi.com/articles/get-rid-mice-and-spiders-essential-oils.htm">Scented mouse deterrents</a>, like peppermint oil, can be effective in the short term. The pungent smells may temporarily repel mice, but they lose effectiveness as the scent fades or mice get used to it. The main drawbacks are frequent reapplication and the fact that these deterrents don't address the root cause of the infestation, such as entry points or food sources. While they can be part of a broader strategy, scented deterrents alone are rarely enough to eliminate a mouse problem.</p></div>

Q: Are German cockroach traps safe for pets?

• <div><p>Gel bait and gel bait traps use poison to kill cockroaches, and aren&rsquo;t safe to use around pets. Many gel bait traps are called &ldquo;child-resistant,&rdquo; but this only means that the traps are hard to rip open for children. Large pets and children are still able to swallow them. If you use gel bait, use it in areas where pets and children can&rsquo;t access them, such as under a washing machine. Another option is to use glue traps, which don&rsquo;t contain pesticides and are safe to use around pets. </p></div>

Q: Can bears smell food in your house?

• <div><p>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.</p></div>
