It’s very uncommon for roaches to bite humans. Cockroaches don’t need humans for food and prefer to be elsewhere than on a living being. They have no poison or powerful pincers to cause any significant damage. However, in very bad infestations cockroaches have been known to search humans for dead skin cells, which leads to them nibbling around feet, hands, and eyelashes. They don’t cause any serious harm, but this is an easy way to spread the diseases cockroaches carry.

The time it will take to see results from a professional exterminator can vary depending on the type of treatment and the severity of the infestation. You may notice a reduction of ants within a few days, but it can take weeks to months for the treatment to take full effect and kill the entire colony of ants. Make sure to discuss what results you can expect with your exterminator and any post-infestation cleaning you should do after the treatment.

When woodpeckers start banging on your walls or roof, they are probably looking for insects to eat, storing nuts for winter, drilling a hole to make a nest, or communicating with other birds to establish territory or find a mate.

The size of the hole can help determine the reason for the pecking. Small irregular holes are a result of insect hunts. Acorn holes are more consistently sized and often fitted with a nut in the middle. Nest holes are large and have rounded edges. If the bird is pecking to mark its territory or attract a mate, it may leave dents rather than holes, and the noise will stop when the mating season starts in spring.

Squirrels rely heavily on their sense of smell and are deterred by a variety of scents. Some of the most effective smells for repelling them include peppermint oil, coffee grounds, white vinegar, garlic, cinnamon, rosemary, and predator urine. They also have a strong aversion to capsaicin, the compound that makes chili peppers hot, making capsaicin-based sprays an effective repellent for areas like gardens or bird feeders. For a DIY solution, you can create a spray from garlic and vinegar and apply it daily. Additionally, squirrels dislike strong, fresh scents, so placing items like strong-smelling soaps or dryer sheets in areas they frequent can also help keep them away.
