				There is a disconnect between the field Tech’s and the scheduling team. The initial Tech seemed knowledgeable and was one time and communicated everything he was going to do and had done.

				Matt always does an excellent job at finding all the places where insects and pests live. He finds them, he eradicates them. I am allergic to hornets and Matt has done such an excellent job I haven’t seen 1 hornet on my property all year. He also alerted me that my gooseberry and current plants can cause blight to my white pines. I much appreciated that knowledge. Matt is meticulous to detail, and always informs me of his findings. Matt is a true professional and a credit to his craft!

				Terminex technician, Riley, was great to work with while he sprayed my poolside back yard for ants/pests. He seemed very knowledgeable regarding the type of application he was putting down. Riley even got to meet Ace, my pet capuchin monkey😆.

Your Questions About Guaranteed Pest Control in Wisconsin

When should I request a re-treatment after my service?

Please allow 7 to 10 days post-treatment for the products to work fully and disrupt pest life cycles. If pests persist beyond this window, contact us immediately for a free re-treatment under your warranty.

Does the guarantee remain if I cancel my recurring plan?

No. The pest-free guarantee is valid only while your recurring service plan is active and current. To maintain your full warranty, continuous quarterly or seasonal treatments are essential.

How does your money-back guarantee work?

If we’ve re-treated your property and still can’t resolve your covered pest problem, Wil-Kil Pest Control will credit or refund your last service payment. We stand firmly behind the quality of our pest control services.

Are treatments safe for pets and children?

Yes. Our products are applied following strict safety protocols. Once dry, usually within 1 to 2 hours, treatment areas are safe for children and pets.

How long should I avoid my home after an interior treatment?

Generally, avoid treated interior spots for 1 to 2 hours until the applications dry. Your technician will notify you if any special treatments require longer precautions.

Do you offer eco-friendly or organic pest control options?

Absolutely. Upon request, we provide environmentally responsible treatments and Integrated Pest Management strategies designed to minimize chemical use while maximizing effectiveness.

Can I transfer my pest control plan and guarantee if I sell my home?

Pest control plans and guarantees are non-transferable and tied to the original account holder. New homeowners must set up their own agreement with Wil-Kil Pest Control. If you’re moving, let us know your new address, we can usually transfer services after inspecting the new property.
