"Just re-upped for another year of coverage with the No Nonsense Termite Company. I had them treat for termites two years ago and have had them out a few times since to perform work under warranty. Everyone they have sent out has been extremely courteous and professional and they always show up on time and perform the work quickly. They came back out today, did another thorough inspection of my property and renewed my warranty for a very reasonable price. If you think you have a termite problem, these guys are for sure the ones to call to make it go away and keep you protected in the future."

"Excellent. Painless. We saw dropping from our wood framed sliding glass door, so we thought it had to be termites. The last time we had termites, we tented and it was awful. We were delighted that this company advertised with KFI radio or else we wouldn't have known about them. The two licensed inspectors were very thorough. They explained how each of their treatments worked. As they found termites, they showed us the droppings. When the technicians arrived (on time) to do the work a few days later, we were pleasantly surprised how considerate they were. They were efficient, knowledgable, and cleaned up after themselves. They even brought their own vacuum cleaner. We would use them again. So nice that we didn't have to move out for a few days and are confident our problem has been taken care of."

"After the prior tenants moved out of the condo I bought, roaches were running around during the day. I had Gorilla come out once while the painters were there and it helped a lot. A few weeks later, there were still some stragglers. So they came out again for no additional charge and put spots of organic pest killer (I have cats and had to be sure it wouldn't hurt them)."

"We had an awesome experience with Josh and his crew at Pest Busters. From the start, Josh stood out for his professionalism and knowledge. Fumigation was a big concern for us, but after a clear explanation of our dry wood termite problem, the rest of the process went really smooth. We couldn't be happier with their guidance."

FAQs for termite pest control service projects in Ontario, CA

Most termite treatments protect your home for one to two years. Once the chemicals break down, colonies can move back in, so schedule a follow-up application before that window closes. Many pros offer ongoing service plans, but it’s smart to wait a few months to confirm the first round worked before you sign a contract. 

If your property sees repeat infestations, ask about a termite bond—an annual agreement that often covers both inspections and any additional treatments.

Drilling into the concrete foundation around your home is not always necessary for termite treatment. While drilling can be highly effective in exterminating subterranean termite colonies, there are alternative methods that work well for termite control. 

Drilling is safer than applying ground-level chemicals, which can be hazardous for children and pets, but a thorough termite treatment plan can be achieved without drilling. Consult with a termite professional to determine the best treatment method for your situation.

DIY termite treatment is possible, but its effectiveness in eliminating termite colonies is far inferior to that of professional treatment. DIY methods address only very minor infestations and do not guarantee complete termite control. 

A professional termite inspection accurately determines the infestation’s extent, and expert treatments—whether chemical or bait systems—ensure that all termite activity is eradicated and the structure is protected.

The best termite treatment is determined by the termite species, the infestation size, and your budget. Liquid termiticide applied to soil is an effective method for eliminating termites, while termite bait systems provide controlled management. 

For severe infestations, gas fumigation or heat tenting delivers thorough extermination solutions. A professional inspection guarantees that the proper treatment is selected to completely eradicate termite activity and secure your home.
