Problems with carpenter ants have only just begun
Carpenter ants are large and polymorphic (meaning several sizes of workers) and are black, reddish-brown, red and black, or light brown in color, depending on the species.
If there is damp wood available, they will make galleries to make their nests.
If they are in the house, they will forage for any foods available, including pet foods, candies, syrups, sugar and other sweet products.
To prevent carpenter ants from entering your home, you should remove or repair all damaged wood that has a moisture problem.
Make sure your gutters are clean so water doesn't back up and damage the siding or the roof, and trim any branches that are touching the house.
If you find a nest, you can spray it with a good natural pesticide, such as Greenbug for Outdoors, not a synthetic one that will do more harm than good.
Silverfish are small insects, up to 3/4 inch long and silvery in color.
Silverfish are attracted to moisture, so you want to make sure you fix any plumbing leaks as soon as possible.
