The Late Summer Rat Problem

Outside rats move inside when temperatures fall

We don’t like it any more than you do, but it’s time to face facts: summer is ending. Fall will be here before we know it, whether we’re ready or not. If you pay attention, you’ll notice the whole world preparing. Squirrels are busy gathering food, ants are reproducing, and bees are swarming.

Unfortunately, some of these fall preparations might be a problem for you. Rodents like mice and rats are gearing up for fall and winter like everything else. The first item on any rat’s fall preparation list is finding a warm place to stay. If you’re not careful, that place could be your home. The only way to keep rats out this late summer is to beat them at their own preparation game. Here’s what those rascally rodents are up to and how to counter them at every turn:

Looking for Food

Rodents have an incredibly keen sense of smell. Rats can interpret all kinds of information from different scents. This sense of smell helps guide rodents toward accessible food supplies. Rats can smell food through walls, even if it’s dry and stored. They can even smell how easily they’ll be able to access it. Rats literally follow their noses to sources of food, letting scents guide them to vulnerable access points.

Rats are looking for consistent sources of food they can access easily. They want to be able to sneak into boxes of food to chow down without anyone noticing. Make that as hard as possible. Store all your dry goods in airtight plastic containers. Clean up your dining and kitchen areas after every meal. Take your garbage out every night. If you can make your food hard for rats to get at, they’ll be much less interested in trying.

Rats start building nests in late summer and fall

Building Nests

Rodents aren’t picky about nesting material. They build small, tightly-packed clumps of various debris, which they rest and eat in. Rats build their nests of paper, insulation, stray fabric, and other trash. They gather these materials by dragging them into dark corners. Often, rats will rip paper or other objects to shreds to use as nesting material. Rodents also rear their young inside these nests, where they can stay safe and hidden.

Rats build their nests in dark, secluded, and warm areas. They want to be able to rest and forage for food without fear of being spotted. Consequently, if there’s a rat nest in your home, it’s probably in your basement, attic, or crawl space. Look for nests in corners or beneath furniture. Rats often build nests into damaged insulation, walls, or other nooks and crannies. Prevent rats from building nests by taking care to keep your basement clean and tidy.

Teething

Rat and mouse teeth never stop growing, so the rodents never stop teething. Rats and mice have to gnaw on something constantly to keep their teeth sharp and healthy. They’re not particularly picky about what they chew on. As long as it’s soft enough to bite down on safely, rats are all over it. Teething is a big reason why rats can be dangerous inside homes. When rats bite down on wiring, they could start dangerous electrical fires.

Rats gnaw on soft materials that they can access while they’re sneaking around. Usually, they’re chewing on boxes, storage materials, fabrics, or wiring. The best way to keep rats from damaging your stuff by chewing on it is to elevate it. Keep vulnerable stored materials in an elevated place where rats can’t reach it. Replace your cardboard boxes with hard plastic ones. Conceal and protect electrical wiring whenever possible, and consider affixing it to the wall.

Rats sneak into homes to find shelter in late summer and fall

Looking for Shelter

Rats have extremely keen perceptive senses developed over centuries of hard-won survival. One of the main reasons why they have these developed senses is so they can prepare for environmental changes early. When they start sensing a season’s change, they start looking for warm shelter right away. Rats use several senses to start searching for shelter. Their whiskers help them locate drafts and warm breezes, which they can follow into structures.

Rats use their heightened senses to find all kinds of access points. Once they find these access points, they can twist and squeeze their way in through surprisingly tiny openings. Rodents frequently squeeze through openings in door and window frames, utility lines, and small foundation cracks. Many rodents can climb surprisingly well to access openings, but most get in via access points close to the ground. Finding and blocking off these access points is the most important thing you can do to prevent rodent infestations.

Rodents are very, very good at preparing for cold weather. One of their most dastardly techniques is sneaking their way inside before we know to look for them. If they’re safely ensconced in your home before the temperatures even drop, they won’t have to worry about your fall defenses!

If rodents start this early, we have to start preventing them this year, too. Follow these tips starting now to keep rodents from infesting your home this fall. It’s not too early to start thinking about winter! If you do end up with rodents now or later, however, remember that you can always give Griffin a call. No matter how prepared your rodents are, we’ll prove we’re even more prepared.

How to Have a Rodent-free New Year

If you’ve ever had a rodent in your home, you know how persistent they can be. You lay out traps, seal off cracks, and even call in pros, but year after year, there they are. It’s easy to get discouraged or even apathetic about the whole process. But not this year. This year things are going to go differently. This year you stop the rodents. We’re here to help.

Sound ambitious? It’s easier than you think! Just follow these four steps, and you’ll be well on your way to creating a rodent-proof environment. Don’t give up! Getting a jump start on this will give you the momentum you need to complete your other resolutions. It all starts here!  

Replace Weatherstripping

replace weatherstripping to keep pests outWeatherstripping is the long, rubber material that makes up the threshold between doors and windows and their frames. This stripping makes an airtight seal between the door or window and the outside air. Without it, outdoor air would slip through the cracks and enter your home. Over time, weatherstripping can wear down. Damaged weatherstripping may not keep outdoor air out, or it may peel away from the threshold all together. Either way, it provides a perfect opportunity for rats and mice.

When outdoor air seeps in, the pressure difference between that air and indoor air creates a vacuum that sucks heat out. Rodents outside feel this heat escaping and follow it to its source: the damaged weatherstripping. Rats and mice can easily bite through or sneak under weatherstripping that’s already been damaged. Examine all the weatherstripping in your house and replace any that looks worn. You can buy inexpensive weatherstripping materials at most hardware stores.

Seal Utility Lines

Seal utility lines to keep pests outMice only need an opening the size of a dime to wriggle their way into your home. Some of the most common openings they find are around your utility lines. Gas, water, and electrical appliances have pipes, vents, and cords that need to enter your home from the outside. Rodents often follow the smell of gas or water along a pipe. Eventually, they’ll reach the opening where that pipe enters the home.

Cutting off this avenue of infiltration is simple. First, walk the perimeter of your home looking for any utility line access points. When you find them, check to see if there’s an opening rodents could use to enter your home. Remember: it can be a small opening. Use caulk or steel wool to seal this opening as snuggly as you can from the outside. To be doubly sure, go inside and repeat the same process. Utility lines are the #2 way rodents get into homes after windows, so don’t neglect this simple chore.

Clean Yard

Keep the lawn clean to keep pests outBefore rodents are attracted to your home, they’re attracted to your yard. All kinds of things bring them there: food, moisture, shelter, even random debris. Food can mean various things in this context. It could be pet treats, vegetables, fruits, or even bird seed. Moisture could come from bird baths and water features, or from sinkholes and puddles. Shelter is anything they can hide in or under to get away from predators. Random debris can be used for nesting or cover.

Keep your lawn mowed short, and prevent weeds from growing in it. If you have a garden, fence it off and protect it from pests. Be careful not to overwater your plants or grass, and don’t let water sit for hours. Keep your yard uncluttered and clear by picking up fallen seeds, branches, leaves, or fruits. Trim hedges and brush to a short, uniform length. It’s less obvious than the other tips, but yard care is an important way to keep rodents out.

Take Out the Trash

Take out the trash frequently to keep pests outRats and mice have truly incredible noses. Not only can they smell much better than we can, they can discern specific information based on smells. Information like where food is, how much there is, and how easy it would be to take. While rodents may come around looking for shelter, they’re probably interested in your home specifically because of food. Nothing attracts pests, including rats and mice, quite like the pungent aroma of garbage. It’s like an all-you-can-eat buffet.

This is another anti-pest tip that’s surprisingly easy to implement. First: line all your garbage and recycling cans with plastic bags. Make sure all the garbage you put in your cans actually ends up in these bags. Next, take the bags out of the cans and to the outdoor dumpster every night before bed. Seal the bags tightly before you throw them out. Keeping your garbage outdoors and away from your home will remove the main thing attracting pests to your home.

 

If these tips sound simple, it’s because they are. If they sound too good to be true, just give them a try! Even if you don’t solve your rodent problem overnight, you’ll be on the right track to a rodent-free new year.

If you need some help making that final push and driving the last of the rodents out of your home, just give Griffin a call. Our rodent experts have been fighting the furry menace since 1929, and they haven’t beat us yet. Have a great, pest-free* new year!
