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.

Vinegar can keep some animals at bay, like deer, rabbits, foxes, and raccoons. Keep in mind that your household pets, like cats and dogs, also don’t like the smell of vinegar. You can soak rags in white vinegar and put them up around your garden beds to keep the pesky critters from eating your plants.

The cost of pest control services depends on various factors, but the average homeowner pays around $175, with a typical range of $100 to $500. Your final cost will be influenced by the type of pest, the size and severity of the infestation, and the number of treatments needed.

Service costs also vary by frequency:

• One-time service: $300–$550

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

• Monthly visits: $40–$70

• Quarterly visits: $100–$300

• Annual visits: $300–$550

For specific pest examples, getting rid of spiders typically costs between $100 and $300, whereas a termite infestation can cost from $230 to $2,500 or more, depending on the extent of the damage.

No single deterrent will work 100 percent of the time, so we suggest combining deterrents to ensure your seed has the best possible chance to grow. Using bird netting over your seed, with physical deterrents like mylar tape coupled with hanging bird feeders at the edges of your growing area—and removing any bird’s nests, if possible—will give your seeds the best possible chance for success.
