Pest Control FAQs, answered by experts

Silverfish can infest a bed, but it’s not likely unless you have a major infestation. Silverfish may be attracted to the fabric of the bed and the dark corners of the mattress, so you should check your bed thoroughly if you are seeing silverfish throughout the house. Seeing them in bed is a bad sign, because it means they are eating your cotton or silk sheets while they’re there.

The cost to hire an exterminator or pest control service is $175 on average, with typical costs ranging from $100 to $500. However, you could spend more depending on several factors, including the type of pest, the size and severity of the infestation, and the number of visits required.

Service costs also vary by frequency:

• One-time service: $300–$550

• Initial visit with ongoing service: $150–$300

• Monthly visits: $40–$70

• Quarterly visits: $100–$300

• Annual visits: $300–$550

The type of pest significantly impacts the price. For example, exterminating spiders typically costs between $100 and $300, while a termite problem can range from $230 to $2,500 or more, depending on the extent of the damage. Routine pest control services can help prevent future infestations and costly damage to your home.

Brown recluse spiders are found in Midwestern and South Central states like Nebraska, Ohio, Texas, and Georgia. While it’s possible to find spiders from the same genus elsewhere in the country, you’re unlikely to find a brown recluse infestation outside of these designated zones. In any case, there are other dangerous spider species across the U.S., so always use caution when dealing with infestations of any kind.

Cockroaches are attracted to the smell of food. They're particularly attracted to grease, meat, cheese, sugar, and starch. Any rotten food such as fruits or vegetables puts off a strong odor that attracts the pests as well. Even dirty clothing can be enticing for cockroaches, which is why they're often found in laundry baskets.

Raccoons should be removed in most cases, especially when they’ve made their way indoors. Even if they seem harmless, raccoons are wild animals that can damage your property and potentially harm you, your family, and your pets. As soon as you notice signs of raccoons on your property, address the situation by securing your garbage and consulting a pro.
