Insect & Rodent Identification — Wells Pest Control, Central Ohio
Identifying the pest you are dealing with is the first and most important step toward effective pest control. Different pests require different treatment approaches — a treatment plan for ants is not the same as one for cockroaches, and rodent control strategies differ significantly from insect control methods. Knowing what you are dealing with helps our licensed technicians arrive at your property prepared with the right products and equipment to address your specific pest problem efficiently.
Wells Pest Control has been helping Central Ohio homeowners and businesses identify and eliminate pests since 1946. Our licensed technicians are trained to identify a wide range of insects, rodents, and other pests common to the Central Ohio region — and to recommend the most appropriate residential pest control or commercial pest management treatment for each situation. Use the information below as a general guide to some of the most common pests we encounter in our service area.

Common Household Insects in Central Ohio
Ants & Carpenter Ants
Ants are among the most common pest complaints in Central Ohio homes and businesses. Common ants enter structures in search of food and moisture — targeting kitchens, pantries, and areas near moisture sources. Carpenter ants are a more serious concern: they tunnel through wood to create nesting galleries, and a significant infestation can cause structural damage over time. Carpenter ants are larger than most ant species and are often found near moisture-damaged wood. If you see large black ants in your home — particularly near window frames, door frames, or bathroom fixtures — contact Wells Pest Control for an inspection.
Cockroaches
Cockroaches are one of the most resilient and problematic household pests. They are nocturnal, so a daytime sighting often indicates a significant population. German cockroaches are the most common species encountered in residential and commercial kitchens and bathrooms. They reproduce rapidly and can become heavily established very quickly. Cockroach infestations are a serious health concern — these insects contaminate food, spread disease-causing bacteria, and trigger allergic reactions and asthma in some individuals.
Spiders
Most spiders encountered in Central Ohio homes are nuisance pests rather than a danger to human health — however, the presence of large numbers of spiders often indicates a significant food source (other insects) in or around the structure. Brown recluse spiders are present in Ohio and can deliver a bite that requires medical attention. If you are seeing unusually large numbers of spiders — particularly brown recluse — contact Wells Pest Control for an inspection and appropriate exterior pest control treatment.
Stinging Insects
Wasps, yellow jackets, hornets, and bees are common in Central Ohio, particularly in summer and early fall. Nests built in or near structures pose a risk to residents and, in the case of yellow jackets and hornets, can be particularly aggressive when disturbed. Flying and stinging insect control is included in our residential pest control plans. Do not attempt to treat a large or established nest yourself — contact our licensed technicians for safe, professional removal.
Common Rodents in Central Ohio
Mice
House mice are the most frequently encountered rodent pest in Central Ohio homes and businesses. They enter structures through gaps as small as a dime, seeking food, warmth, and shelter — particularly as temperatures drop in the fall. Mice contaminate food, gnaw on wiring and structural materials, and carry diseases. Signs of mouse activity include droppings, gnaw marks, nesting materials, and evidence of food contamination. Rodent control services from Wells Pest Control address active infestations and help identify and seal entry points.
Rats
Norway rats are less common than mice in residential settings but are frequently encountered in commercial food facilities, older buildings, and properties near water sources. Rats are significantly larger than mice, more destructive, and can be more difficult to eliminate. A rat problem in a commercial setting can have serious consequences for regulatory compliance and public health. If you suspect a rat infestation, contact Wells Pest Control promptly for a commercial pest management assessment.
Asian Lady Beetles
Asian lady beetles are a significant nuisance pest in Central Ohio, particularly in fall when large numbers aggregate on the exterior of homes and enter through gaps around windows, doors, and siding. Once inside, they congregate in wall voids and attic spaces and become active on warm winter days. Unlike their appearance suggests, these beetles are not harmless — they can bite, leave staining secretions on surfaces, and create significant frustration for homeowners. Wells Pest Control provides exterior pest control treatments for Asian lady beetle management. Visit our Asian Lady Beetles page for specific treatment tips and information.
Insect & Rodent Identification Frequently Asked Questions
How can I tell if I have mice or rats?
The most reliable indicators of rodent presence are droppings (mouse droppings are small, dark, and rice-shaped; rat droppings are significantly larger), gnaw marks on food packaging, structural materials, or wiring, nesting materials, and audible sounds of movement in walls or ceilings — particularly at night. Mice and rats are primarily nocturnal, so a daytime sighting typically indicates a larger population. If you are unsure what rodent you are dealing with, contact Wells Pest Control — our licensed technicians can identify the species and recommend the appropriate rodent control services.
Are the spiders in my Central Ohio home dangerous?
The vast majority of spiders encountered in Central Ohio homes are nuisance pests and are not medically significant. The most commonly encountered house spiders cause no harm and actually help control other insects. However, the brown recluse spider — which is present in Ohio — can deliver a venomous bite that may require medical treatment in some cases. If you are finding spiders you believe may be brown recluse, contact Wells Pest Control for an identification and assessment. We can also provide exterior pest control treatments that reduce overall spider activity by eliminating the insect populations that attract them.
Why do I suddenly have so many ants in my home?
Ant activity in homes is typically seasonal, increasing in spring and summer as ant colonies become more active and begin foraging more aggressively for food and moisture. Entry into homes often increases after heavy rain, as saturated soil drives ants to seek dry shelter. A sudden increase in ant activity can also indicate that a colony has established itself inside or very near your home's structure — which is a more serious situation requiring professional residential pest control treatment. Contact Wells Pest Control for an inspection if you are seeing persistent or escalating ant activity.
