Crazy Ant built its name on ant work. Clark still handles that, and a good deal more. Here is the short version of what the team can take care of. If you want full service details, or you are ready to book, start on the Clark Pest Control Fresno page.
This is the service most people start with. It covers the common household pests in one visit instead of a separate call for each one. A technician treats the inside where there is activity, then works the outside of the house, the foundation line, the eaves, and the entry points where pests get in. If you are not sure what you are dealing with, this is the right place to begin. See the general pest control page for what is included.
Year-Round Pest-Away is the ongoing version. We come back on a set schedule and keep treating the exterior, so pests stop making it indoors in the first place. It is built around the seasons, which matters in the Central Valley where the pressure shifts from ants in summer to rodents in fall. Details are on the Year-Round Pest-Away page.
Rats and mice head indoors when the nights cool off. You usually hear them in the attic or the walls before you ever see one. Droppings under the sink, chewed food packaging, and a musty smell in the garage are the other giveaways. Traps alone do not solve it. A technician finds the gaps they are using, because if those stay open the next group moves in a few weeks later. More on the rodent control page.
German cockroaches are the kitchen and bathroom problem. They breed fast and hide in warm, tight spaces close to food and water. Oriental and Turkestan cockroaches are the ones that come in from outside, through drains, garage gaps, and water meter boxes. Store sprays scatter them deeper into the walls and make the job harder. Bait and targeted treatment work. Our cockroach identification guide shows what the different species look like.
Most spiders around here are harmless and actually eat other insects. People still do not want them in the house. Black widows are the one to take seriously. They like garage corners, woodpiles, and anything that sits on the ground outside and does not get moved. Treatment clears webs and egg sacs, then treats the spots where spiders hunt. See the spider control page.
Bed bugs travel in luggage and used furniture. A backpack that spent a night in the wrong hotel room does it too. The first sign is usually small dark spots along a mattress seam or behind the headboard, not the bugs themselves. This is not a do-it-yourself pest. Store products push them into other rooms and turn one bedroom into a whole house. Clark's bed bug service starts with an inspection, then treatment of the infested area. More on the bed bug treatment page.
Standing water is the whole story with mosquitoes. A saucer under a plant pot is enough to start a batch. Long Central Valley summers stretch the season out, and irrigation, pools that are sitting idle, and clogged gutters keep it going. Treatment hits the shaded spots where mosquitoes rest during the day and addresses the breeding sites on the property. See the mosquito control page.
Crazy Ant handled snails, and they are a real Central Valley problem. Irrigation, ground cover, and shaded beds keep them going most of the year, and they chew through a vegetable garden fast. At Clark this falls under yard and garden service rather than general pest control, so it is a separate conversation from an indoor treatment. Ask about it when you call, or see the lawn and garden care page.
Argentine ants are the most common ant in this area by a wide margin. Carpenter ants, odorous house ants, and pavement ants turn up too. Identify the species first, bait at the colony, then treat inside and out. Full detail is on the ant control page, and there is more on crazy ants specifically just below.
Crazy ants get their name from how they move. Most ants march in a tidy line. Crazy ants dart around in fast, jerky, seemingly random directions, which makes them easy to spot even before you look closely. The name covers several species in the Paratrechina and Nylanderia genera. Two come up most often in the United States: the longhorn crazy ant (Paratrechina longicornis), also called the black crazy ant, and the tawny crazy ant (Nylanderia fulva).
Sometimes, but not the way they are in Texas or Florida. Longhorn crazy ants show up in California mainly indoors, in heated buildings, warehouses, and goods shipped in from warmer regions. They are a tropical species and do not survive Central Valley winters outdoors. Tawny crazy ants, the ones that swarm electrical equipment across the Gulf Coast, are not established in California.
Worth knowing: most ants people call crazy ants around Fresno turn out to be Argentine ants. They are the most common ant in California, and when they scatter after a spray they can look just as erratic. Correct identification changes the treatment, which is why a technician confirms the species before anyone treats anything.
Crazy ant colonies have many queens, not one. They also nest away from where they forage, often outdoors under mulch, leaf litter, or objects on the ground, then travel long distances to reach food inside. Spraying the ants you can see kills workers and does nothing to the queens. Worse, most over-the-counter sprays are repellents, so they push the colony to split into new satellite nests. That is why the problem comes back bigger a few weeks later. Argentine ants react the same way, which is one more reason identification matters.
If you have already sprayed, that is fine. Just stop before your appointment, and wipe visible trails with soapy water to erase the scent line.
Expect to see ants for a week or two after baiting. That is the bait doing its job as workers carry it back to the nest. For ongoing protection after the colony is cleared, ask about Year-Round Pest-Away®. Full detail on our approach is on the ant control page.
Free inspections apply to pest control service. Inspections required for a real estate transaction are a separate, billable service.

Central Valley heat drives most of the ant pressure here. Once outdoor water sources dry up, usually from June into September, Argentine ants push indoors and trail along baseboards, sinks, and counters hunting for moisture. Heavy rain does the same thing in reverse, flooding shallow outdoor nests and sending the colony looking for dry ground. Come fall, the calls shift to rodents as rats and mice look for a warm place to wait out the winter.
