How many fleas is considered an infestation?

• <div><p>Since fleas reproduce so quickly, the mere presence of one flea could mean you have an infestation on your hands. Hundreds and even thousands of fleas can lurk in your pet’s fur, carpet, furniture, and even your body. If you see fleas jumping on household items or notice your pet scratching more than usual, those are signs of infestation.</p></div>

Q: What does a rodent infestation smell like?

• <div><p>A rodent infestation often has a distinctive, unpleasant smell. The most common odor is a strong, musky scent, similar to stale ammonia, which comes from mouse urine. As the infestation grows, the smell can become more intense. You might also notice a foul, decomposing odor if mice or rats die inside the walls or hidden areas. This combination of smells is a clear sign of a rodent problem and should prompt immediate action to address the infestation.</p></div>

Q: Does rock landscaping attract snakes and other critters?

• <div><p>Rocks are less likely to attract snakes and other critters because their prey (termites, ticks, and other insects) don&rsquo;t usually inhabit this environment. However, if you have placed together rocks with large spaces in between or near a source of water, you may find a snake or an occasional chipmunk seeking shelter.</p></div>

Q: Why are wasps so aggressive?

• <div><p>Wasps are aggressive to protect their nests. Although they are deemed aggressive, they only act that way when they feel their nests are threatened. They can also act aggressive when there is a lack of food available. Most wasps will leave you alone if you stay clear of their nests.</p></div>

Pest Control questions, answered by experts

It can be difficult to know what type of animal is in your attic until you see it. But several clues can help you narrow down the suspects:

Sounds: Smaller animals like rats and mice make scurrying and tapping/gnawing sounds. Larger animals like raccoons and opossums make louder clambering noises. Also, note when animals are noisy: Squirrels are active during the day, while rats are busiest at night.
Droppings: Rats and mice leave small, rice-shaped droppings (the rat’s version is significantly larger). Bigger droppings belong to larger critters like raccoons. As long as you’re not squeamish, an image search can help you identify what you’re seeing in your attic.

When in doubt, take photos of damage or other evidence and show them to an experienced pest control pro.
