Should I let cellar spiders live?

• <div><p>Yes. While cellar spiders can seem creepy or scary, they’re essential to the ecosystem. They feed on smaller insects in your home or elsewhere, keeping those populations in check. They’re also food for birds and small animals, so if you let a cellar spider live and simply transport it outside your house, you’re letting the natural cycle continue undisturbed. </p></div>

Q: Will bees leave on their own?

• <div><p>If you&rsquo;re dealing with a bee colony on your property, you might wonder if they&rsquo;ll leave naturally over time. The answer depends on their circumstances. Bees often relocate if the hive becomes overcrowded, food is scarce, or they face a threat. With that said, if a hive&rsquo;s location is safe, warm, and with plentiful food sources, they are unlikely to relocate on their own, and the hive may persist for many generations.</p></div>

Q: Why do I have so many flies all of the sudden?

• <div><p>If it seems like many flies appeared in your yard overnight, don&rsquo;t be concerned. A single fly can lay over 200 eggs per day, so having one in your yard could lead to dozens more the next day. That&rsquo;s why it&rsquo;s important to eliminate flies from outside your home before they take up residence.</p></div>

Q: How often should mosquito fogging be done?

• <div><p>Mosquito fogging should be done every two days during the first week of treatment. This level of frequency helps to interrupt the mosquito breeding cycle and prevent them from laying eggs in your yard. After the first week, mosquito fogging can be reduced to a schedule of once a week.</p></div>

Q: Will filling gaps help with pest problems?

• <div><p>Yes, filling gaps can help with pest problems in your home. Sealing baseboard gaps reduces small-insect entry points into your home. Even tiny spaces provide pathways for pests, so addressing all gaps throughout your home creates a more effective barrier than spot treatments in individual rooms.</p></div>
