Las Vegas & Southern Nevada Weed Control Experts

Do you have weeds that are ruining your beautifully landscaped yard? Sometimes it seems like no matter what you do, they continue to grow back. This usually means spending hundreds of dollars on weed killer products or hours of back-breaking work pulling each weed by hand.

Our Las Vegas weed control service will take care of all of those pesky weeds so you don’t have to! We send a licensed pest- and weed-control technician to your house. All sites of weed growth are then sprayed with a mixture of products that are selected to work best on the types of weeds that are growing. This kills most of the existing weeds within a few days. The technician will then spray all treatable areas with a pre-emergent herbicide. This product is specially developed to prevent new weeds from growing.

As every yard is different and weeds can be a pain, we have the same Satisfaction Guarantee that we provide with our regular pest control service. If any weeds pop up between your regular scheduled service, we will come back again for free and take care of them at no cost.

The best part of this service is that it builds on itself. The more treatments we complete, the better the product works at keeping the weeds gone. Call us today to get an estimate scheduled and see how we can help keep your yard looking great!

FAQs of Weed Control

Q: How often do you need to spray?
A: Every 6 months

Q: When do you recommend having the service completed?
A: Anytime you are seeing weeds. The earlier we start, the better the product works. Typically we spray in early-Spring and early-Fall as that is when most weeds are beginning to sprout.

Q: Will this affect existing plants?
A: Our spot treatment is to kill any weeds that are already sprouted or established. We WILL NOT spray this on any other plants as it could affect them as well. The pre-emergent that is used to prevent the re-growth of weeds is safe for most other plants. People will even use pre-emergent in their gardens without any effect on existing or established plants.

Q: What types of weeds does this service cover?
A: Any types of weeds that are common around households. This includes broad-leaf weeds like bull thistle, chickweed, or dandelions; and grassy weeds like cheatgrass, crabgrass, or rattail fescue.

Q: Can you spray in my rock landscape?
A: Yes! Our weed control service works perfectly in rock and xeriscape landscapes.

Bed Bugs

Bed bugs have been nearly absent from developed countries for the last 30 years, thanks largely to the effectiveness of long-lasting insecticide products like DDT that were used extensively during the period around World War II.


In the southwest United States, scorpion control is a priority. Many types of scorpions are native to the desert environment and encounters are common. Not all scorpions are poisonous, but all have a sting that will cause pain and damage to people and pets. The Bark Scorpion is considered the most poisonous of all scorpions in the United States and for most of us it’s in our back yard.


Termites cost millions of dollars in damage a year to property owners. Termites don’t just attack homes; they infest commercial property as well. At Preventive, we offer affordable and dependable way to eliminate your current termite problem.
