Boxelder Bugs in Spring

Boxelder bugs in spring

When is it not boxelder season? It seems like these gross red-and-black bugs are everywhere, all the time. Around this time of year, however, you may notice they’re around even more than usual. Boxelders wake up and start moving around starting in early spring. Unfortunately, they often wake up and start moving around in your home.

But why are boxelders around your home so much this spring? Where are they coming from? What do they want? Most importantly, how can you get them to go away? Here’s everything you need to know about boxelder bugs in spring.

What they are

What boxelders bugs areEven if you don’t know boxelder bugs by name, you almost certainly know them by sight. These bugs are extremely common in the fall and spring, when they swarm around windows, porches, and door frames. Boxelder bugs are a type of “true bug” in the Hemiptera order, similar to stink bugs. Like stink bugs, they can also release a foul-smelling scent if threatened or crushed. Despite these similarities, however, boxelder bugs are not considered stink bugs.

Boxelder bugs have .5 inch long black bodies with distinctive bright red or orange ‘X’-shaped markings on their backs. They tend to congregate on warm, heat-reflecting surfaces such as windows or porches in large groups. Boxelder bugs feed almost exclusively on the flowers, leaves, and seeds of boxelder trees. These bugs enter reproductive season in mid-spring or early summer, shortly after re-emerging from winter hiding places. Homes with southern or western exposure might be particularly attractive to boxelder bugs.

Why they’re back

why boxelders return in springLike stink bugs, boxelder bugs never really leave Michigan. Instead, they overwinter in hidden, secluded places where they can survive the cold. Boxelders survive winter temperatures by bunching together and squeezing into tight nooks and crannies. They seek out warm, dark places where they can remain unnoticed and dormant for months at a time. Unlike stink bugs, they don’t fully enter diapause. During warm enough winter days, boxelders may temporarily re-emerge.

Boxelder bugs re-emerge from their winter hiding places as soon as they can survive outdoor temperatures. In other words, the boxelders you find in your home in spring were probably there all winter. Boxelders are very temperature-sensitive and crave warmth, so they’re commonly found around sunny windows and reflective surfaces. The bugs congregate in large swarms in order to keep one another warm and exchange information via pheromones. These swarms may sometimes get trapped or lost inside homes as they try to find their way out.  

What they want

what boxelder bugs wantWhen boxelder bugs re-emerge from the overwintering sites, their top priority is food. Remaining inactive for long periods is very taxing to boxelder bugs, so they need to recharge quickly. During this period, adult boxelders are usually encountered on the ground, where they eat low vegetation and fallen seeds. Boxelders seek out female acer trees for their plentiful fallen seeds and flowers. Boxelders don’t begin mating until they’ve acquired enough energy from feeding, which can take weeks.

Once boxelder bugs find their way outside and acquire sufficient energy, they usually move to a nearby acer tree outside. From there, they lay eggs, eat, and prepare to begin the whole cycle again. Like stink bugs, boxelder bugs do not eat, mate, or reproduce indoors. They only enter buildings in order to stay warm, and they’re only interested in leaving come spring. Boxelders aren’t dangerous, but their stench and sheer number can make them a serious nuisance.

What you can do

what you can do to prevent boxelder bugsThe most important thing to remember about boxelders control is that when they die, their bodies attract other pests. Don’t kill the boxelders you encounter in your home, especially if they’re in your walls. Instead, vacuum or sweep up the boxelders you encounter and dispose of them outdoors. You could also use soapy water to kill the boxelders, as long as you remove the bodies after they die. Scrub down any areas where boxelders congregated with soapy water, too.

After you’ve cleared out the existing boxelders, you have some time to make sure they don’t come back. Boxelders won’t try getting back into your home until early fall, when they need to overwinter again. Before this happens, try to find and seal off the ways they get in. Boxelders usually find cracks and crevices near window sills, door frames, and baseboards. Use caulk to re-seal these openings, and you should be able to keep boxelders from getting in next season.

 

Don’t beat yourself up for having boxelders in your home this spring. Those little pests are as tricky and resourceful as they are smelly. There’s a reason there are so many of them.

Pests That Wake Up in Spring

Pests that wake up in spring

The whole world seems to come back to life in spring. Unfortunately, “the whole world” includes some things we wish would stay sleeping. Along with grass, flowers, trees, and birds, a whole host of Michigan’s most annoying pests wake up every spring.

When pests wake up in spring, they’re usually hungry, thirsty, and ready to find mates. To make up for their long winters off, they tend to pursue these activities ferociously. Their single-minded pursuits make pest problems all-too-common this time every year. Here are the pests you’re bound to run into this spring, what they’re up to, and the problems they cause.

Boxelder bugs

boxelder bugsStarting in early fall, boxelder bugs go looking for dry, warm places where they can wait out the winter. Unfortunately, those dry, warm places often include our homes. When spring comes around, boxelders become active again to seek their newly rejuvenated food sources and, eventually, to reproduce. When that happens, they vacate their winter hideaways en masse. If they were hanging out in your home over winter, you’re going to run into them again this spring.

Boxelder bugs are obviously a nuisance, but luckily they’re not a dangerous one. These pests don’t bite, spread disease, eat fabrics or stored foods, or lay eggs indoors. Instead, they simply vacate the premises to seek the seeds and flowers of acer trees like the boxelder. The nuisance part comes from how many of the gross bugs you may notice vacating. Boxelder excretions and feces may also stain window ledges and other favored areas.

Stink bugs

stink bugsStink bugs follow a similar seasonal routine to boxelder bugs, and they’re around for the same reasons. During fall, they desperately seek out any warm place where they can wait out the winter. Once they’re in position, they go dormant until outdoor temperatures rise back up to survivable temperatures. Once that happens, they wake up with one thing on their mind: mating. In their mad scramble to get back outdoors, however, they tend to get lost… or stuck.

Like boxelder bugs, stink bugs don’t reproduce or nest indoors, cause disease, or bite. They do… stink, however. When threatened or crushed, stink bugs secrete a foul-smelling substance from a special scent gland. This scent smells like rotten vegetables or coriander. The more stink bugs secrete at once, the more powerful the stench. These secretions can also leave behind a dark yellow stain on carpets, furniture, or window sills.

Carpenter ants

carpenter antsDuring spring, the infamous wood-infesters come marching in to build their nests and search for water. Carpenter ant invasions tend to be the most noticeable during the start of the season. Starting in mid spring, the reproductive carpenter ant castes swarm in order to seek mates and start new colonies. After mating, queen ants seek good places to lay their eggs. These eggs hatch into workers, and the infestation begins in earnest.

Carpenter ants are a problem because they make their colony nesting grounds by boring through wood. The tunnels they carve compromise the structural integrity of wood products. Carpenter ants don’t actually eat the wood they infest. Instead, they have to hunt for sources of protein and sugar. You may find foragers in your kitchen, basement, or garden. Keep a close eye out for swarmers, in particular. If these flying ants get trapped in your home, chances are their nest is also inside your home.

Pavement ants

During this time, you may notice swarms of larger-than-average, reddish-black ants flying in large clusters. After mating, pavement ants lay eggs in tight crevices (hence their association with pavement, and the cracks in it). When young pavement ants emerge, they start looking for food almost immediately.

Pavement ants are most often encountered in groups in your kitchen. They break down and carry off all sorts of stored food, especially grains and sugars. When they find food, they tend to stick around. It’s not uncommon to find ants infesting cabinets, pantries, cupboards, and anywhere else they could find food. They’ll attack any scraps they can get their mandibles on. Unlike other pests on this list, they can stay active as long as they’re warm and they have food.

 

Spring should be a wonderful, refreshing time of year–especially after a brutal Michigan winter. Don’t let pests ruin that for you.
