"Iâ m a very picky property manager; frugal but withnletfectionistic tendencies. So many people for hire seem to be either grossly expensive or completely unreliable/incompetent. I shopped around for help removing squirrels in my attic crawl space. Hearing people over formalize the situation as they led me up to huge bills or suggested ongoing prices to make sure the problems was solved was stressful/disappointing. However when Matt the owner called me, he immediately seemed more frank and forthright. He tuned in to my situation and brought up questions showing his level of expertise that placed far more expensive did not think to ask. He was available, ready, and patient. When he came, he was professional and thorough, quick. I was very very happy with Bearclaw Wildlife and with Matt in particular. I definitely will refer back to him with any pest or wildlife issues at my properties. Nice to see a person take pride in their work and their companyâ s name. Keep up the excellence Matt! Thank you!"

"That there was a follow up done by (Matt) their quality control manager and we were able to come up with some points in seeing a more improved lawn in the future. They even sent out a inspector to do a quality inspection."

Pest Control FAQs, answered by experts

In most cases, a mother bird will return to a disturbed nest after the disturbance has passed. However, it can be hard for a mother bird to find a relocated nest. So, while it’s false that a mother bird will abandon her nest if it’s been disturbed, it’s not a good idea to relocate a nest with live babies or eggs in it.

Setting up an animal trap in your yard largely depends on where you live and the type of critter you're dealing with. In many states, trapping nuisance animals like squirrels, rats, or raccoons is allowed, sometimes without needing a permit. However, certain wildlife species are protected, and not all states have lenient catch-and-release regulations.

Before placing a trap, check your local laws to avoid fines or other legal issues. Some areas allow DIY trapping, while others may require professional assistance. Most areas require a professional to relocate the animal once trapped. Consulting a pro ensures you handle the situation responsibly, humanely, and within the law.

Humans attract fleas with their body heat, the carbon dioxide (CO2) they exhale, body odors, and movement. Fleas love hiding in warm, dark places like hair and scalps, armpits, and groin areas. Fleas prefer to feed on pets and wildlife, but they do bite humans when other warm-blooded mammals aren’t available.

The right snake trap depends on your needs and the species of snake. Glue traps are the easiest to handle but are inhumane and may catch and kill other animals, like squirrels, birds, and mice. Cage traps catch snakes alive so they can be released elsewhere. Minnow traps are the best choice for water snakes. 

Once the animals and their young are out of the house, remove the nest and locate any entry points. Some may be difficult to find because some animals can fit through very small holes. Once you’ve located as many entry points as possible, use materials such as metal or masonry to block off the entry. Ideally, you should choose materials that most animals cannot chew through. Create a one-way door or flap to allow animals to leave but not return. Additional methods include using repellants designed to make an area unappealing to the types of animals that find your home so inviting.
