Mosquito control starts with finding where the insects breed, which is usually standing water, and then treats the shaded vegetation where adults rest. Removing standing water is the step that reduces the population most, so it is partly a homeowner job.
Mosquitoes need water to breed, and most summer calls around Montpelier come from places where water sits still. Old tires, clogged gutters, tarps, livestock tanks, low spots in the yard, ditches and wet margins along the river bottom all hold water long enough for a population to build. Culex mosquitoes lay their egg rafts on standing water, and some of that water is polluted, such as a barnyard drain or a livestock trough.
The Indiana Department of Health has run mosquito and bird surveillance since 2000. It monitors Culex mosquitoes with gravid traps, tests pooled mosquitoes by real-time RT-PCR, and uses dead birds such as crows, blue jays, hawks and falcons as an early warning, since those birds are highly sensitive to the West Nile virus. The state expects West Nile activity to continue until the first hard freeze. A Purdue article from August 2025 reported 511 positive mosquito pools across 78 Indiana counties and 10 confirmed human cases statewide at that point in the season.
Mosquito work is about the breeding and resting places around a property. It is not a diagnosis and does not change anyone's health risk. The technician walks the property, finds the water and shaded spots, and explains what the owner can remove and what the service will treat. Call (855) 974-4733 at any hour to ask about a visit.
Mosquito numbers follow water. A wet spring, heavy rain and warm weather give eggs more places to hatch, so a summer after a wet spell usually brings more calls.
Mosquitoes lay eggs on or near water, and the larvae develop in it. After heavy rain, low spots, tires, buckets and ditches fill, and the population can build quickly in the warm weather that follows. A dry spell can slow things down, but a single storm can refill the same spots within days.
Because the cause is water, the most useful work is the survey and the water removal. A technician can say which spots hold water after rain and which the owner can empty.
West Nile virus circulates between birds and mosquitoes. The Indiana Department of Health tracks positive mosquito pools, dead birds and human and equine cases, and this page does not describe any health effects.
The state's surveillance uses mosquitoes trapped across the state and dead birds reported to it. Its dashboard shows human and equine cases and positive mosquito pools, and the August 2025 Purdue figures cited on this page are statewide, not local. A technician does not diagnose or assess anyone's health.
Work on a property is about reducing breeding water and resting places near the house and barn. Questions about symptoms or a bite belong with a doctor, and questions about the state's data belong with the state agency.
No single visit clears a property. Breeding water comes back after rain, and adults move in from nearby places, so the work is repeated through the warm season.
A treatment on the resting spots reduces adults for a while, but it does not stop new eggs from being laid in the next puddle. The water survey and the owner's removal of standing water do more to lower the population than any single treatment.
A property next to a river bottom or a large farm will see more mosquitoes than a yard in town, because the breeding water and resting shade are both larger. The plan is set for the property and adjusted after each visit.
This page does not describe a county or district program. The service on this site is private work for the property, and the owner's own water removal is the step with the most effect.
Households and farms around the area arrange mosquito work privately, and the technician works on the property that has called. The state's surveillance is separate from any service visit and runs on its own schedule.
The owner can do a great deal before a technician arrives: emptying containers, clearing gutters, cleaning and covering livestock water where practical, and filling low spots that hold water.
The size of the property, the amount of standing water and shaded vegetation, the length of river or creek margin, the number of outbuildings and livestock tanks, and the number of follow-up visits all change the work. The price is explained and approved before any work starts.
A small yard with a few containers is a different job from a farmstead with several livestock tanks, ditches and a shaded windbreak. The water to survey, the vegetation to treat and access to the back of the property all affect the time the work takes.
How often the work repeats through the season changes the price too. The technician explains the price and the plan on site, and the customer approves it before any work begins.
Do not use a fogger or total-release product inside a house for mosquitoes, because it does not reach the breeding water and leaves residue on surfaces. Do not pour oil, gasoline or other chemicals into standing water, livestock tanks, ponds or ditches to kill larvae, since that harms animals and the water. Do not apply a product near a pond, a garden or a watering trough unless the label allows it there.
Phones are answered 24/7. The caller describes where the problem is worst, when it started, what has been wet recently, and whether animals are kept on the property. A visit the same day is possible only when a technician is free, and no arrival time is promised.
The technician walks the property and looks for every place water can sit: gutters, downspouts, tires, buckets, tarps, low spots, ditches, livestock tanks and wet margins near a river or creek. This is the most important step, because removing breeding water reduces the population most.
Adult mosquitoes rest in dense, shaded vegetation during the day, so the technician checks shrubs, the tall grass along a fence line, dark corners of outbuildings and the shady side of the house. Resting spots are often close to the breeding water, and the survey connects the two.
Treatment is placed on the resting vegetation and shaded margins where adults spend the day, chosen for the property and the animals and people who use it. Water that cannot be emptied is treated in the way the label allows. The technician explains what is used and where, and what the owner should keep out of water.
Mosquito work is repeated through the warm season, because new water appears after rain and adults move in from nearby places. The technician leaves a short list of water to remove before the next visit, since the service cannot reach every standing spot on its own.
Around a house, breeding water is usually in gutters, tires, buckets, planters and low corners of the lawn. The resting places are the shrubs along the foundation and the shaded side of the house. The technician treats the shaded margins and explains how to clear gutters and empty containers. The yard plan repeats through the warm months.
Livestock tanks, water troughs, drainage ditches and low spots near a barn hold water and organic matter, the kind of standing water Culex mosquitoes use. The technician checks each one, recommends the cleaning or covering that belongs to the owner, and treats the shaded areas near the barn where adults rest.
The river bottoms along the Salamonie, the Wabash and the Mississinewa, and the creek edges that run into them, are wet and shaded and hold water after rain. Adults rest in the brush along the bank, and breeding water collects in low spots and backwaters. The work is a survey of the whole margin, with treatment placed where adults rest close to the water.

The Salamonie River runs through Montpelier, and the low ground along it holds water after a wet spell [search]. The town sits on the high ground on the south side of the river, so the worst standing water is usually in low corners, ditches and yards closer to the bottom. The survey starts at the river edge when a property is near it.
Farmyards across the grain country hold water in livestock tanks, ditches and low spots along fence rows, and a farm's shaded windbreak or brush line is where adults rest. Shamrock Lakes has its own water, from its lakes and their shorelines [search], and lakeside lots are surveyed for the same breeding and resting places as a farmyard.
The Wabash River runs through Bluffton and the Mississinewa runs through Eaton [background]. Along those river bottoms the breeding water sits in backwaters and low spots, and the owner is asked to keep low corners drained where practical.

Pest activity around Montpelier follows a cold Indiana year.
Indiana Department of Health entomologists have found the blacklegged tick in all but three Indiana counties, and a 2025 Purdue Extension summary describes it as established in nearly all of them.
A treatment on the resting spots reduces the adults around a property, but it does not stop the virus from circulating in the state. The state tracks West Nile through trapped mosquitoes and dead birds, and a doctor can answer questions about symptoms or a bite.
Remove standing water. Empty containers, clear gutters, drain low spots where practical, and clean or cover livestock water. Breeding water matters more than any treatment, because mosquitoes need it to produce the next generation.
Rain refills puddles, tires, buckets and ditches, and the eggs laid in them hatch in the warm weather that follows. Adults also move in from nearby water, which is why the work is repeated through the warm months.
A technician chooses placement and method with the animals in mind, and the product label sets the limits. Livestock areas and water troughs need particular care, so tell the technician which animals use the area.
The state's surveillance is about trapping and testing mosquitoes and tracking birds and cases, and the Indiana Department of Health publishes the data. Work on a property is arranged separately, through a private service.
Often the first step is the water survey, since a few mosquitoes usually mean a few breeding spots. The technician can say whether treatment is needed and where. Removing the water first is often enough to reduce the problem.
