When to Call an Exterminator

A pest invasion can be a homeowner’s worst nightmare.

Uninvited insects, rodents, or other pests infiltrating your home and wreaking havoc can be unsettling. Some minor pest issues can be addressed with DIY methods. However, there are situations where calling a professional exterminator is not only wise but necessary.

So, here are some definite red flags to let you know when to contact a professional exterminator to detect and deal with hidden threats.

1. Widespread Infestations

If you notice pests in various parts of your home or if the problem spreads rapidly, it’s a clear sign that you need professional help.

Widespread infestations can quickly become unmanageable, and attempting to tackle them on your own may prove ineffective. A professional exterminator has the experience, knowledge, and tools to identify the source of the infestation and implement comprehensive control measures.

2. Pests That Cannot Be Identified

Not all pests are recognizable, and misidentifying them can lead to ineffective treatment or even make the problem worse.

Professional exterminators are trained to identify a wide range of pests accurately. Whether you’re dealing with a less common species or an entirely new threat, they can diagnose the issue correctly and choose the most appropriate treatment methods.

3. Structural Damage

Certain pests, such as termites and carpenter ants, can cause severe structural damage to your home. Signs of structural damage, such as sagging floors, warped walls, or hollow-sounding wood, should prompt an immediate call to a professional exterminator. They can assess the extent of the damage, eliminate the pests, and recommend necessary repairs.

4. Health Risks

Some pests carry diseases or allergens that can pose health risks to you and your family. These pests include rodents, cockroaches, and ticks.

If you suspect that pests in your home are endangering your health, such as through contaminated food or bites, it’s crucial to seek professional pest control. They can eliminate the threat and advise you on preventive measures to protect your health.

5. Recurring Infestations

Dealing with a recurring pest problem can be incredibly frustrating. If you’ve tried DIY treatments multiple times and failed, then it’s time to call in a professional exterminator.

Recurring infestations often indicate that the root cause of the problem hasn’t been effectively addressed. A professional exterminator can perform a thorough inspection, identify the source, and implement a lasting solution.

6. Complex Pest Species

Certain pests require specialized knowledge and equipment to control effectively. For example, bed bugs are notorious for their resilience and ability to hide in cracks and crevices. Attempting to eliminate them without the expertise of a professional exterminator can result in frustration and prolonged infestations. A trained exterminator understands the behavior and biology of complex pests and can apply targeted treatments to eradicate them.

7. Environmental Concerns

When dealing with pests in a home with sensitive individuals or pets, there may be concerns about the safety of DIY pesticides. Many professional exterminators use environmentally friendly and low-toxicity treatments that minimize risks to humans and pets while effectively controlling pests. They can provide peace of mind that the treatment is both safe and effective.

8. Presale or Pre Purchase Inspection

If you’re planning to sell or buy a home, getting a pest inspection is a common part of the process. Professional exterminators can conduct a thorough inspection to identify any existing or potential pest issues. This information is crucial for negotiations and ensuring that the home is pest-free before moving in.

While some minor pest problems can be handled with DIY methods, detecting hidden threats and dealing with severe infestations or complex pests require a professional exterminator. They have the knowledge and tools to identify and eliminate pests effectively and can offer long-term solutions to prevent future infestations.

Don’t wait until the problem becomes overwhelming; if you suspect hidden pests in your home, contact a professional exterminator to protect your property and your peace of mind.

Troy inspected my home carefully, made a recommendation, gave me a bid and did the work competently. He explained the termite life cycle n how the pesticide treatment worked. He indicated they may swarm again but after 90 days all evidence of live termites should be gone. He explained his warranty n yearly inspection.

They have great knowledge about the biology and behavior of termites as well as years of experience working with residential customers. They knew exactly what needed to be done, were on time, worked hard, and patiently answered any questions I had. Having them do the job gave me great confidence that my pest problem will be promptly resolved.

Troy is the best! As realtors, we work with Pest Inspectors a LOT and have had issues with multiple companies being wrong or missing some sort of infestation. Troy is the ONLY guy we can always trust will do an amazing job. He is quick to respond and usually can get the job done very quickly! We really appreciate you!

Look no further. They offer free initial inspections. Robert from Pest Shield came out and quickly developed a plan to solve our yellow jacket problem. His advice provided quick and complete eradication of the yellow jackets and a plan for any future concern. Pest Shield offered the honest and pressure free service we appreciate. Pest Shield is now our “go to” for any future pest control issue.

Great service, called them about an issue I was having with yellow jackets flying in and out of the siding of my house, Troy came out the very next day and assessed the situation and got the problem fixed, he even checked in a couple days later to make sure the yellow jackets were not coming back. I would highly recommend them for the super quick service they provided and the fact that they check up on their work. Thanks again
