5 Star Review for Harper Pest Control

I woke up to a mess of ants invading the kitchen and so I called Harper Pest Control. They were out immediately to remedy the situation. This was extremely helpful because of my six kids that are constantly running and playing through the kitchen and throughout the house, so I really appreciate their clean green products and methods of taking care of the pests quickly and safely. The ants were gone the same day, within hours.

If you have a pest problem, I highly recommend calling Harper Pest Control.

Common Pests That We Service in Costa Mesa CA


Ants enter your family home looking for shelter from the weather or for food or water. It is critical to stop ants before they enter a house. We will treat the entire colony. Harper Pest Control technicians will search for Ant trails and look for nests. For some people baiting rather than spraying does better for others. Some ants - Argentine Ants for example have multiple queens so when they see the combination Raid can or Borax you created, one or more of the Queens will break apart and set colonies for a while on the land and to your house. Heart services are here at the clinic.‍ Our Harper Pest Control Costa Mesa Office will help you get rid of Ants.


Harper Pest Control treats for spiders and removed webs and eggs around the perimeter of the house (the first level). Spiders such as Black Widows have been known for hiding under furniture and in the ground. Most spiders are not poisonous though black and brown widow spiders can be damaging to kids and pets at times when they disturb one's home. Our Harper Pest Control Costa Mesa Office will help you get rid of Spiders.

Rats & Mice

Rodents can have small gestational periods and very large litters. Mice rats spread disease through droppings and bring other unwanted pests, such as fleas and mites to your house. The staff at Harper Pest Control will begin a rodent service by locating the source of infestation. We will customize the action plan using rodenticides or traps. After the removal of rodents from the home, we will point out their entry points and provide exclusion work to discourage future rodents from coming back to the home. Whenever the rodent is removed we are able to mark the entry point to ensure that your home is safe for the future.


Cockroach infestation is common in Orange County and San Diego County. They contain poisonous fungi which transmit diseases and thrive in rapid succession without addressing them immediately. German Cockroaches, Brown-Banded cockroaches, Oriental cockroaches, and American cockroaches are the most common.

Bed Bugs

Bed bugs are prolific breeders and can travel freely across walls often taking rides between people or pets or touching items bought or purchased for personal use. Bloodsucking species that eat the human body. Our Harper Pest Control Costa Mesa Office will help you get rid of Bed Bugs.
