Prevent and Treat Infestations









Natural Science Exterminating doesn’t just fix pest problems – we prevent them throughout Orange County, Los Angeles County, and Riverside County.

Annual or semi-annual maintenance is the most effective way to mitigate the risk of stubborn pests – especially termites.

Our goal is to avoid expensive spot treatments and make tent fumigation a last resort.

We’ll help you protect your property from pest-related damages and deterioration.

We’ll assess your home for infestation warning signs and possible pest entry points.

All of our preventative extermination products are eco-friendly and safe for children and pets.

Our maintenance contracts are flexible to meet your schedule and specific requirements.

Maintenance isn’t free – but preventative measures cost far less than emergency exterminations and reparations.


I have a yearly maintenance contract for termites, which more than pays for itself given the number of swarms I've had – both dry wood and subterranean varieties.

I use their eco-friendly solutions as we have pets, and they got rid of our ant and spider problem. I really appreciate that they allow me to change from monthly [service] in the summer to bi-monthly in the winter.

Natural Science has been our go-to guys for over a decade. When an agent says we need to use any other company, we say, “No thanks, we have our own team.


Real Estate Investor and General Contractor
After one company told us we needed to tent our house for a full chemical termite treatment, we called Dave DeGraw at Natural Science for a second opinion. After a no cost/no obligation comprehensive inspection, he said we only needed spot treatments with orange oil. He was in and out in a day, no dangerous chemicals and even expertly repaired all the wood damage. Six months later, we’re still termite free.

Dave DeGraw and his crew at Natural Science are only one of two inspection and exterminating companies we call for every home we sell. Timely, thorough and fair are just three of the reasons we count on them. New home owners love them as well.
