"I used them for mosquito control Weather has a major impact on scheduling, so it was hard to set firm dates for service. Always showed up once they were scheduled. Treatments provided significant, but not total relief from mosquito problem. Price was good compared to other services. Techs were always pleasant and professional."

Pest Control FAQs, answered by experts

Bed bugs do not always go away after one treatment. A small case may be a one-and-done deal, but many infestations need about two to four visits within about six weeks to fully eradicate the pests in your home. It’s critical to stick to your treatment plan to ensure any existing eggs don’t hatch and create a new infestation.

Some of the best smells for keeping squirrels away are those that have a spicy or pungent odor. This includes pepper, garlic powder, vinegar, mint, and coffee. Just be careful when handling cayenne or chili pepper. Don’t touch your face to prevent getting some in your eyes, and be sure to keep it away from children and pets.

You may find fleas in your bed if they followed you there on your pet or your clothing. While they will need you or an animal as a host, they can hide in bedding since it is warm and out of sight. If you spot signs of fleas or see live fleas in your bed, hire a flea control specialist immediately to eradicate the infestation and prevent it from spreading further.

Yes, exterminators are a type of pest control professional that is qualified to remove wasps safely and effectively. Exterminators will inspect the wasp problem, administer professional-grade treatments, and apply preventative measures to avoid a future infestation. Consult a local exterminator about your wasp problem as soon as you identify it.

Pros offer targeted treatments that are more effective and long-lasting, using specialized equipment and knowledge.
