The Role of Pest Control in Zoos and Aquariums

Pests can be more than annoying. They can cause property damage and pose health problems. Rodents such as rats and mice chew electric wires, which can lead to fires, and they can spread diseases such as Hantavirus Pulmonary Syndrome, Leptospirosis, Plague, and Salmonella.

Physical pest control includes:

  • Picking and shaking plants.
  • Using fly swatters and mouse traps.
  • Clearing debris from the yard.

Chemical pest control includes the use of insecticides and other chemicals.

Whether they crawl, fly, squirm, or slither, insects are the most abundant animals on Earth. They form the biological foundation of terrestrial ecosystems, recycling nutrients, pollinating crops and flowers, and controlling pest populations. They are essential to the global food chain and biodiversity, and they support a wide range of other species, including amphibians, reptiles, birds, mammals and fish. However, by the end of this century up to 40% of insect species may disappear due to habitat loss, and their numbers are declining around the world.

Insects also directly impact human health. They transmit diseases to people and livestock, and they can disrupt food production by destroying cultivated plants and reducing animal forage. Traditionally, humans have managed these interactions through pesticides, but the rise of resistant organisms is changing the landscape.

While some insects cause problems for people and livestock, others perform critical ecological functions. For example, bees and other pollinators increase crop yields. Ground beetles reduce soil erosion and aerate the earth. Dung beetles recycle and bury animal waste, thereby lowering overall methane emissions from dairy and cattle farms. Insects play other vital roles in agriculture: They decompose organic matter, cycle nutrients and disperse seeds, and they control populations of pathogens, predators, parasitoids, disease vectors and competitors.

At Cornell AES professional greenhouses, staff have used biocontrols — encouraging one living thing to control another problematic living thing – for more than 20 years. The approach is a part of the integrated pest management system used to maintain a healthy and productive conservatory environment.

Biological control is the mass rearing and release of a pest’s natural enemies, such as predatory insects that feed on or parasitize the target insect. This is a relatively safe and environmentally friendly alternative to chemical pesticides, which can have unintended consequences. It requires careful research to find suitable natural enemies, and a long process to prepare the enemy for release. It includes quarantine to eliminate harmful pathogens and to ensure the enemy doesn’t have negative impacts on native species that are not pests, or on other natural enemies of the pest. It also involves releasing the enemy at the proper time in both the pest and natural enemy life cycles.

Rodents

Rodents (rodentia) are a major cause of pest problems and nuisance in residential, commercial, agricultural, and wildland settings. They cost billions of dollars in lost crops, spoil food stored by humans, and carry disease-causing pathogens, including bubonic plague, typhus, and hanta fever. Accidentally introduced species like rats and mice also destroy native wildlife and have contributed to the extinction of island birds such as the dodo.

Rodents are omnivorous, but their diet usually includes fruits, seeds, and grain. They are opportunistic feeders and will invade any food sources they can access, including grain silos, kitchen garbage, dumpsters, and unprotected bird feed. They are prolific breeders and can quickly develop into a serious problem when not controlled.

The most important factor in controlling rodents is sanitation. This means storing foods in sealed containers, addressing spills and crumbs immediately, and regularly inspecting interior spaces for signs of rodent activity, including droppings, gnaw marks, grease and sebum marks on pathways used by rodents, and urine (using a black light). Regularly cleaning up droppings and removing bird feed will help reduce rodent populations as well.

When rodents do invade buildings, the most effective control measures include exclusion, physical/mechanical controls, and occupant education. Exclusion measures include removing accessible entrance points and sealing them with appropriate materials. Physical/mechanical controls include snap traps, glue boards, repeating catch-all devices, and live traps. These can be placed in non-visible, inaccessible locations such as behind sinks, custodial closets, or in garages. Carefully placing bait blocks or other nontoxic monitoring baits in tamper-resistant stations is also effective.

Rats are active at night and can be sighted from dusk to dawn. Mice typically nest in wall voids or in cardboard boxes, wooden or plastic pallets, heating units, and appliances. Inspect cluttered spaces for evidence of rodents, such as droppings or pilfered food, and check walls and ceilings for grease and gnaw marks. Place traps and bait stations in areas where rodents are most active at night, and along travel ways or near entry points. Reset and monitor traps and bait stations frequently. Place a sign explaining the purpose of the treatment to encourage occupant compliance.

Birds

Whether in tropical rainforests, or on Midwest farms, birds play an important role in controlling insect populations. Over the years, scientists have discovered that when bird populations decline, so do insect pests. Often, this is because of the presence of pesticides on or near crops and in surrounding habitat. These pesticides, called neonicotinoids (neonics), are extremely toxic and can be absorbed through the skin, inhaled, or ingested by birds. Neonics can also be dispersed by wind, spray drift, or dust particles, and they can leach into soil and waterways.

Birds have long been natural predators of insect pests and can help control them by consuming large numbers of them during an outbreak. Birds also recognize that many insect pests are infected with parasites, and they tend to prey only on healthy insects. By reducing the number of parasitized bugs in the population, they can significantly reduce bug outbreaks.

In addition to direct bird predation of insect pests, birds may also indirectly influence bug populations through bioaccumulation and shifts in diet. For example, when an outbreak of one type of insect occurs, such as a tree borers, some birds will alter their feeding patterns to consume only that species of insect. They can do this by changing their search image or location, which increases the efficiency with which they can find this new food source. As a result, the overall population of that species of insect will increase, as will the survival rate of its offspring.

Another way that birds aid in pest control is by distributing seeds, which allows plants to regrow and replace the ones that have been damaged or killed by insect pests. When bird populations decrease, this seed distribution function is lost, which can lead to decreased crop production.

In general, the value that birds provide for human beings in terms of ecosystem services is immeasurable. Taking steps to create and maintain bird habitat on farms can help reduce the need for chemical pesticides, which can damage crops and cause health problems in humans. For example, encouraging farmers to install bird boxes and providing hedgerows and woodlots in an agricultural landscape can attract and retain birds that will aid in pest control without the need for harmful chemicals.

Other Animals

Pest control programs at zoos may involve several steps, including prevention (keeping a pest from becoming a problem), suppression (reducing a population to an acceptable level), and eradication (destroying a pest). The Animal Welfare Act requires licensed animal facilities to have pest management programs. The goals of these programs are to provide an environment for the animals that is free of pests, and to cause as little harm as possible to the animals, property, and people.

A pest control program should include routine inspections of the zoo to identify potential problems and prevent them from occurring. Sanitation and food storage procedures are also important parts of any pest management plan. Zoos should have appropriate barriers (e.g., fencing, netting) to prevent access by some pests. In addition, zoos should encourage visitors to feed animals only from designated areas.

Other animals, such as birds, reptiles, amphibians, and mammals, often kill or eat pests. Certain climate conditions also affect the behavior of pests and their hosts. Rain or freezing temperatures can kill or suppress plant-eating pests, and drought can limit a pest’s ability to reproduce.

Many natural enemies of pests, such as parasites, predators, pathogens, and fungi, also help control their populations. For example, aphids, one of the most difficult crop pests for growers to manage, are eaten by ladybugs. In turn, the ladybugs lay hundreds of eggs that eat even more aphids.

The natural enemy’s role in controlling a pest depends on its food supply, its shelter, and the availability of its young. A natural enemy’s presence in an area is also affected by its weather and the availability of water, shelter, and overwintering sites. Natural features such as mountains and large bodies of water can restrict pests by limiting their roosts, habitats, and food sources. Some natural enemies need to be reintroduced into the target area on a regular basis to maintain their effectiveness. This is especially true for some fungi and pathogens, which require an initial introduction to begin their control of a pest. In general, the use of natural enemies is a more environmentally friendly strategy than chemical controls.

What is Electrician?

Electricians Fort Worth install and maintain electrical wiring, systems and fixtures. They inspect wires and other components to ensure they meet safety standards.

They also use their skills to troubleshoot problems and develop effective solutions. This can include identifying circuitry and other elements to pinpoint the source of an issue.

Always consult with an electrician before attempting any DIY work. Faulty switches and outlets can pose serious hazards, especially if you don’t follow proper safety protocol.

Installing Wiring

The electrical wiring system in a home or commercial building is what ensures that lights, appliances and other devices are powered by electricity. Electricians use special tools to identify faulty wires, replace damaged circuit breakers or panels, and repair or upgrade switches, outlets, and light fixtures. They may also install energy-efficient lighting solutions or other home automation products.

When installing wiring, electricians need to make sure that all the components are rated and sized properly. They also need to make sure that all connections are made securely. A loose wire can create a fire or shock hazard, so it is important for electricians to check the connections on all electrical devices before leaving a room.

Before starting any electrical work, it is important for electricians to locate and mark the spots on a wall where any junction boxes will be placed. This is done with masking tape or directly on the wall if it hasn’t been drywalled yet. Then, using a drill, they will punch holes in the walls to accept the wires. Then, they will run the cables to the main electrical service panel in the house or commercial building. Depending on the project, they may need to run these cables under floors or in attics.

The cable that runs to the electrical outlet or switch has different types of wires inside, depending on what they are used for. The black or “hot” wires carry current to the fixture. The other wires, called neutral or ground, return the current back to the electrical service panel. The sheathing that covers the individual wires is colored, which makes it easy for an electrician to know what each one does.

After all the wires have been run, the electrician will connect them to the proper terminals on the outlets or switches. This is typically done by securing them with screws on the side of the outlet or using a clamp to secure them on the back of the switch. It is important to follow the manufacturer’s instructions when connecting the wires. Then, the last step is to test the outlets and switches for safety. Before touching any bare wires, electricians should use a multimeter to check for voltage and be sure that all connections are tight.

Repairing Wiring

Most homeowners need electrical repairs at some time or another. If your fuse box or circuit breaker keeps blowing, or if an outlet or switch doesn’t work properly, call in a pro. If you live in an older home, the wiring could be outdated and may need upgrading. Old aluminum or knob-and-tube wires can also pose a danger if they’re exposed or chewed on by rodents.

Electrical repair jobs often require the ability to think on your feet and solve problems quickly. This is particularly important if you’re working on new fixtures or complicated wiring tasks. You’ll also need strong math skills to calculate currents, volts and wire lengths. It’s also helpful to have good reading comprehension, as you’ll be required to read and interpret rules and regulations throughout your career.

Before you start any electrical repair, always make sure the power supply to what you’re working on is completely disconnected and that you’re wearing appropriate safety gear. This includes sturdy work gloves, rubber or plastic soled shoes and a hard hat. Ensure you’ve thoroughly inspected the area for any other potential hazards. If you encounter any bare wires, ensure these are properly protected or removed by cutting and crimping them to prevent future problems.

The first step of any electrical repair is to determine what caused the problem. Often, it’s a simple issue such as overloading the circuit. Having your TV, computer, refrigerator and air conditioner all running on the same circuit can cause it to trip or overheat. A professional can help you redistribute your appliances and add an additional service panel if needed.

Another common electrical repair is fixing outlets, switches and fixtures. These are the components that you use every day, so they can experience lots of wear and tear. If you notice that an outlet or switch isn’t working correctly, or if the light fixture is dim or flickering, it’s important to have this fixed as soon as possible. In some cases, the culprit is a frayed or broken wire, so it’s important to check for these and replace them as necessary.

Troubleshooting

When a fixture or piece of electrical equipment malfunctions, electricians use troubleshooting skills to figure out what the issue is. This involves careful observation and the help of diagnostic equipment. In addition to these tools, an electrician may also need to take notes and write down the results of their tests. They can then follow a set of steps to determine what the problem is and how it can be fixed.

Flickering lights are a common electrical issue that many homeowners have to deal with. This symptom can indicate that the wiring isn’t functioning properly, which could lead to overheating and even fires. It can also be caused by frayed cords, so it’s important to regularly check the connections of your light switches and outlets for any signs of wear and tear.

A skilled electrician will be able to identify the source of the problem, whether it is the result of a loose wire or a faulty circuit breaker. They will also have to take note of any previous repairs that might have been made on the electrical fixture in question.

Once they have all of the necessary information, the electrician will start analyzing the circuit in question. They will look for a set of values that are expected when the fixture is working correctly and then compare this to what they are actually seeing with their diagnostic tools. This process is crucial because it helps them zero in on the exact problem and how it can be solved.

When troubleshooting an electrical system, it is important to make sure that the power is turned off before starting any work. This will prevent any accidental shocks, which can be very dangerous. It is also a good idea to avoid using any appliances or lights until the problem has been resolved, since this will help to prevent further damage from occurring.

One of the most important things that an electrician needs to know is how to properly use their diagnostic tools. This includes knowing how to read and interpret electrical schematics. This will allow them to better understand how the various parts of the electrical fixture work together to provide proper function. It will also help them to spot any potential problems that might be causing future issues.

Maintaining Wiring

An electrician can perform a number of electrical maintenance tasks to keep your property safe and operating efficiently. This work typically involves inspecting and testing all components in a residential or commercial building to ensure they are functioning properly. It also includes ensuring the wiring is secure and protected from rodents and other environmental hazards.

The majority of electrical maintenance is preventive in nature, which means the electrician will look for signs of trouble and address them before they become larger issues. This includes checking all outlets, switches and other components for signs of damage or deterioration. It also includes inspecting for signs of overheating, which can be a sign of problems with wiring or the connections to wires.

Other electrical maintenance tasks an electrician may perform include installing whole-house surge protectors to reduce the risk of damaging voltage spikes from entering your home and frying wiring or other appliances. Electricians can also install more efficient lighting and appliances, such as those that run on solar or wind power, which can significantly lower your energy bills and reduce your carbon footprint.

During an electrical maintenance visit, your electrician will check your circuit breakers to see if any are continually tripping. This could be a sign that some parts of your system are overloaded or that you are using appliances that require more amperage than your current system can handle. An electrician can help you determine the cause of the problem and recommend a solution that is appropriate for your needs.

In addition to performing a visual inspection of all your electrical equipment, an electrician will test for loose or worn-out connections and make sure all wiring is securely fastened. They can also look for any signs of discoloration on insulation, which could indicate overheated connections that require immediate attention. Your electrician can also check for signs of wear and tear on control wiring, which is used to manage the electrical systems of complex machinery or buildings.

While some maintenance is unavoidable, preventing electrical problems can significantly reduce your energy costs and prevent unnecessary repairs. You can do your part by not yank cords out of outlets, ensuring all plugs fit snugly in outlet openings and not overloading your circuits or power strips. Having a multimeter handy can also be a great way to keep track of your electrical usage and know when it is time to call a professional.
