What to spray to keep spiders away?

• <div><p>Experts have mixed opinions about spraying spiders. <a href="https://entomologytoday.org/2018/01/22/do-chestnut-lemon-or-peppermint-scents-repel-spiders/#:~:text=Results%20were%20mixed,the%20three%20species.">A recent study</a> found that chestnut and peppermint oil have a repelling effect on some spider species, but were ineffective at repelling others. You should consult with an expert exterminator to find out what works best to repel the spiders living in and around your home.</p></div>

Do bats in the attic cause damage?

• <div><p>Yes, bats can cause quite a bit of damage to the attic. Their weight and movement from flying around can damage insulation, and they can chew through wiring and the walls. As if this isn’t enough, they leave their droppings throughout, which carry harmful bacteria and is dangerous for humans to breathe in, not to mention the extremely foul-smelling odor.</p></div>

What should I do if I see a tick crawling in my house?

• <div><p>If you find a tick inside crawling in the house, remember not to just step on it or try to crush it. Ticks have hard bodies and it’s hard to kill them this way. Instead, pick it up with toilet paper and flush it. You can also place it in a sealed bag, or kill it by placing it in alcohol. </p></div>

Q: Why are there suddenly bugs in my house?

• <div><p>Having bugs in our houses is quite normal. However, if you notice a sudden uptick in quantity, there's often a reason behind it. Seasonal weather changes, particularly warm to cool, drive bugs indoors as they look for comfort. Structural damage to your home can open up new ways for them to get in, and a new water leak somewhere in the house can invite them to get comfortable.</p></div>

Q: Will leaving lights on keep roaches away?

• <div><p>Leaving lights on is not an effective or foolproof method for keeping cockroaches away. While roaches are nocturnal and prefer darkness, light alone is not enough to stop them, especially if they are seeking food, water, or shelter. A bright light might temporarily discourage them, but hungry or determined roaches will often adapt and venture into lit areas. For more effective cockroach control, it is better to focus on proven prevention methods. These include maintaining cleanliness by eliminating food crumbs, sealing cracks and entry points, reducing clutter that provides hiding spots, and fixing any moisture issues. Using traps or repellents can also be part of a comprehensive strategy.</p></div>
