While we most often think of wildlife being a problem in the winter months, these animals don’t just disappear when the weather gets warm. Wildlife can still be quite active in the summer, wreaking havoc on our homes and gardens. Whatever the time of year, preventing and controlling these nuisance pests is of the utmost importance, as they not only cause damage to homes and property, but can also pose significant health risks to both humans and pets. Wildlife prevention (also known as wildlife exclusion) is the first line of control against critters; however, once they have established themselves in or around your home, wildlife removal becomes a more necessary option. Let’s look at some common summer wildlife, as well as ways to exclude them from your home.
Snakes are cold-blooded animals that require heat and sunlight for energy. They are more active in the summer months because they require more energy for mating. Too much exposure can overheat them so snakes are typically more active in the early morning and late evenings or at night in the summertime. They will also seek out shelter during the hottest parts of the day in cool, dark places like underneath rocks and decks or in basements. Snakes will choose where they live based on the availability of food, shelter, and shade.
To prevent snakes this summer:
- Clear away yard clutter, piles of leaves, and wood.
- Keep your grass mowed short to eliminate coverage.
- Trim bushes and hedges regularly.
- Make sure birdseed doesn’t fall on the ground and clean it up if it does.
- Block access to any potential hibernation areas.
- Walk the perimeter of your home and seal, cover, or repair any crack or crevice that is greater than 1/4″.
- Check your garage, garage doors, windows, and exterior doors for gaps and seal them.
- Seal any gaps around water pipes, electrical lines, sump pumps, and other spots that utilities enter your home.
- Ventilate crawlspaces and repair leaky faucets and pipes as these attract pests which, in turn, attract snakes.
While bats are scary to many people, they are actually quite beneficial at keeping insect populations down. In the southern United States, many bat species are active year-round. Bats enter homes through openings. They can cause damage in homes by ruining insulation, causing structural damage when their urine soaks through to sheet rock or particle board, and their urine and feces causing health concerns for occupants of the home. Bats also carry serious diseases such as rabies, with 1 to 3 cases of bat transmitted rabies occurring each year. Bats are nocturnal and emerge at dusk in search of food. Female bats search for summer roosts where they stay until they have their young. For this reason, unless there is a threat to public health, eviction or exclusion of bats should not take place between April and August. Colonies will disband in late summer as bats leave for their winter roosts.
To prevent bats in the summer:
- If you have a bat in your home, locate any openings leading to living spaces in your home from attics, garages, walls, etc and seal them off.
- Close all doors to the room where the bat is and open all windows and exterior doors to allow the bat to escape.
- Inspect and caulk any openings on the exterior of your home that are larger than 1/4″.
- Use window screens, chimney caps, and screen vents.
- Fill any electrical and plumbing holes with steel wool or caulk.
- If you find an entry point, cover it with plastic sheeting or bird netting and then once all the bats are gone, seal it off completely.
- Professional removal is recommended. Professional wildlife pest control will:
- Assess any entry points.
- Install one-way systems to allow bats to exit but not return.
- Seal any entry points.
- Clear, decontaminate, and deodorize the affected area.
Armadillos mate in the fall, with their young born in the spring, making them very active in the summer months. They prefer habitats near streams or other water sources with sandy or clay soil. They are often found in forests, woodlands, prairies, salt marshes, coastal dunes, pastures, cemeteries, parks, golf courses, and crop lands. They love to nest in rock piles, around trees and shrubs, and under rock slabs. Armadillos dig burrows that can be up to 25 feet long, which can significantly damage tree roots. These burrows can also cause flooding if they are dug around crawlspaces, patios, or walkways. Armadillos have poorly developed teeth and limited mobility. they have poor eyesight but a keen sense of smell. They have very few natural predators. They are strong diggers which they rely on to find shelter and food and causing most of the damage around your home and property. Armadillos will eat fruit (especially from gardens and compost piles), grubs, worms, beetles, wasps, ants, millipedes, centipedes, and snails.
To prevent armadillos in the summer:
- Eliminate food sources by getting rid of insects around your home.
- Clean up any rotten fruit that may fall to the ground.
- Maintain proper landscaping by keeping grass mowed and shrubs and trees trimmed.
- Install sturdy fencing that goes at least 1 foot into the ground and at a slight angle.
- Eliminate any areas of excess moisture in your yard as this leads to more grubs and worms.
- Set traps and relocate the armadillos.
Opossum females are laden with their young in the summer months, making them more active in their search for food. Opossums are found throughout the United States. They live in trees and will stay in them as much as possible. They also prefer wet areas like marshes and swamps. Opossums are nocturnal and will forage for food at night. They are beneficial in they eat harmful and unwanted pests around your home. They prefer to eat snails, slugs, spiders, cockroaches, rats, mice and snakes. They will also eat nuts, grass, fruit, roadkill, and garbage. They are rarely aggressive and will play dead when they feel threatened.
To prevent opossums this summer:
- Don’t leave pet food or water out overnight.
- Don’t leave garage doors, pet doors, or unscreened windows open at night.
- Pick up any fruit that has fallen from trees.
- Cover garbage cans at night.
- Clear out any dense bushes, shrubbery, or woodpiles.
- Keep swimming pools and hot tubs covered at night.
- Keep trees and shrubbery trimmed away from fences.
Raccoons are highly intelligent and curious animals. They typically give birth to their young in April and May, making them very active in the summer months. They are found throughout the United States. They prefer to live in heavily wooded areas with access to trees, water, and vegetation. They are extremely adaptable, however, and will make their homes in attics, sewers, barns, and sheds. They are dexterous, capable of opening doors, jars, bottles, and latches. They are known to carry several bacterial diseases. Raccoons are nocturnal animals, searching for food at night. They will eat almost anything including birds, eggs, fish, shellfish, frogs, fruit, insects, nuts, seeds, and even snakes. They are known to destroy gardens, tip over garbage cans, and cause structural damage in their quest for food.
To prevent raccoons this summer:
- Secure trash can lids, especially at night.
- Double bag any trash that contains meat.
- Remove brush and keep shrubbery trimmed.
- Keep grass mowed short.
- Seal any entry points to chimneys, eaves, and attics.
- Install motion detecting sprinklers or strobe lights.
- Remove any fallen fruit from trees.
- Bring bird feeders and pet food in at night.
- Seal pet doors at night.
Rats are active year-round. The summer provides them with ample sources of food making them very active. They are also busy making burrows and storing food in preparation for the winter. Rats can reproduce very quickly so control and elimination can be extremely difficult. They are excellent climbers and are well adapted to living in human environments. Rats can contaminate food, cause fire hazards by chewing through wires, and their urine and feces can cause serious health concerns.
To prevent rats this summer:
- Fill or seal any cracks, crevices, and holes found in foundations or siding.
- Install chimney caps and cover vents with screens.
- Replace any torn screens on windows and doors.
- Remove clutter from garages and storage areas.
- Try to use plastic storage bins versus cardboard boxes.
- Store firewood away from your home.
- Remove bird feeders and pet food at night.
- Keep food and pet food stored in airtight containers.
- Use trash cans with lids.
- Keep your kitchen clean from crumbs and spills.
- Empty the trash regularly.
Prevention is always a good first step at keeping wildlife away. Once you have a wildlife issue, however, prevention usually needs to shift to removal and exclusion. Consider contacting a professional wildlife control company who can assess your wildlife issue and provide you with the safest and most appropriate treatment and prevention options.
