Great service from Marichal! Marichal was responsive, listened to my needs and gave me several options for service, and came the same day. He was prompt, friendly, thorough, and careful with all of my plants, furniture, etc. I especially appreciate how he guarantees his work between services!

Noticed a lot of small spiders running around. Could not figure out where it's coming from. Call the guy and he found an egg sag hanging at the window. He cleared it and sprayed around the house. Pretty happy guy.

I highly recommend hiring Marichal for all of your pest control problems. He is friendly, knowledgeable, and effective. My husband and I had been dealing with an ant problem for months and we finally gave up. I called Marichal and he came to help us the next day. He has been very proactive with checking in on us and he's very responsive.
Thank you for helping us with our ant invasion, you saved our food and my sanity!
