Insecticide For Boxelder Bugs

The key to solving a problem is to understand the nature of the problem. The more you know about your box elder bug infestation, the more effective and efficient you will be in combatting it. The article that follows will provide you with information on how to identify common box elder bugs, how they got into your home, what signs to look for (both at home and in your neighborhood) and how to remove them from a structure and eliminate their existence from the environment.

Insecticide For Boxelder Bugs

Boxelder bugs (Boisea trivittata) are named for their primary host, the boxelder tree. One of the less destructive agricultural pests, boxelder bugs do infrequent damage to apples, peaches, grapes, strawberries, plums and non-fruiting trees including maple and ash. A bigger nuisance to homeowners, they seek and enter houses in colonies of hundreds, even thousands of insects as cold weather approaches, congregating in walls and warm basements, making themselves at home all through winter and occasionally emerging into kitchens, living rooms, bed rooms and other human-inhabited spaces. There’s nothing like watching your toddler bring a stray, otherwise harmless boxelder bug that’s making its way across the carpet up to her mouth. It’s an experiment children won’t likely repeat. Boxelder bugs, though mostly scentless, give off a pungent odor when disturbed or crushed. Also offensive: the accumulation of excrement and dead bugs that fall from the colonies inside walls and other hard-to-access places.

Identification

Adults, the stage most often seen in homes, are dark with three distinct orange or red stripes, the first centered behind its head, the other two running along the sides of its body. The adult’s abdomen is also orange. About 1/2 inch long, it’s dark wings cross along its back. Eggs, found on leaves, the seed pods of boxelder trees, and in ground vegetation, are yellow and clustered in groups that begin to redden as the nymph develops. Nymphs go through five stages, continuing to turn red as they mature. Adults are sometimes mistakenly identified as stink bugs, which they generally resemble.

Life Cycle

Adults survive the winter sheltered beneath loose tree bark, in plant debris, or in homes, garages and outbuildings. They emerge as the weather warms in spring. Staying close to the ground, they feed for two weeks on boxelder seeds and other vegetation before starting the mating cycle. Female bugs fly up female boxelder trees and lay eggs on seed pods and the undersides of leaves. They will also leave eggs on stems and branches. Eggs take 10-14 days to hatch. During the summer, all stages of the boxelder can be found in and around host trees. While nymphs continue to develop into the fall, only adults survive cold weather.

Damage

Box elder bugs are sap suckers, penetrating plant tissue with their considerable proboscis and using secretions to make it consumable. They almost exclusively feed on the acer family of maple trees and vines that includes the boxelder and its spinning “helicopter” seed pods, but have also been known to feed on fruit during dry summers. Infestations on box elder trees may cause its leaves to yellow and curl or leave spots on stems and new growth. Most trees survive. Damage to grapes, peaches, and other soft fruits is mostly cosmetic, appearing as depressions, sometimes as bruises. While a nuisance, boxelder bugs do relatively little damage to fruit crops, preferring to feed and procreate in its namesake tree.

Indoors, the bugs can be a major problem. While they don’t normally cause structural damage to homes or contaminate food sources (individuals will occasionally show up in dried beans and flour if not stored in tightly sealed containers), they can be a source of filth, odor and displeasure due to their sheer numbers. Warm weather or an increase in home heating may convince individual boxelder bugs that spring has arrived and they will enter a family’s living space in search of a way outside. In late summer and autumn, then they gather in groups much like swarms of bees on the sun-facing, preferably white side of homes and garages where their sheer numbers will discolor the building’s side if allowed to stay.

How to Control

Indoor and outdoor boxelder control are interrelated. Destroying boxelder colonies outdoors means few bugs looking for a way into our home come fall. Denying places in your home for boxelders to overwinter means fewer numbers laying eggs in your trees next spring and summer.

Most outdoor boxelder damage is minor and, most years, won’t require treatment most years. Some years will produce more boxelder bugs than others. Dry years may encourage the bugs to seek out fruit. Wind plays a great role in the dispersal of flying boxelder bugs.

Chemical pesticides are a poor option for boxelder infestations. Their use indoors can pose a hazard. Dusting of colonies may kill thousands of bugs but will only encourage other insects and rodents who feed on the dead bodies. The common and troublesome carpet beetle is attracted to dead boxelder remains. There it feeds and lays egg, guaranteeing another generation of increased numbers to damage in your home.

Here are several techniques to control boxelder bugs:

• Preventing boxelders from entering your home is the single most important defense. Seal around window frames, where utilities enter the house, cracks in the foundations and under eaves. Make sure doors are weather stripped at the bottom, leaving no space. Screen off vent pipes and other roof openings with fine screen to prevent the bug’s entry.
• Repair any loose siding which, like loose bark on a tree, allows the bugs to get behind the siding and against the house. Patch any cracks in plaster or stucco- sided houses.
• Eliminate wood piles, landscape debris and other places boxelder bugs will gather to survive the winter.
• Boxelders found in clusters on trees or the sunny side of houses can be sprayed away with a garden hose. A hard spraying is sometimes enough to convince the surviving bugs they should go somewhere else.
• Hot water between 160-180˚F will kill the bugs but, at these temperatures, can also burn the sprayer. Use extreme caution if you have a source of water this hot to use and do so only outside.
• Trees can be sprayed with horticultural oil early in the season as boxelder bugs begin to emerge. Cover thoroughly making sure to get under loose bark as best possible. Spray only while the tree is still dormant or in green bud stage.
• Swarms found on trees and houses can be sprayed with insecticidal soap. Repeated spraying may be necessary.
• Pyrethrin sprays will kill boxelders at all levels of their lifecycle. It’s a good choice for middle and late season use when the bugs may exist in various stages of its development, egg through adult.
• Sometimes your best weapon when facing colonies of boxelder bugs is a shop-vac. Vacuum colonies from the sides of houses and around window sills into a bagless, wet-dry vac canister with a quarter to half inch of soapy water in the bottom which will suffocate the bugs. If you find and can access boxelder colonies behind walls, remove them with the vacuum.
• Sprinkling borax or diatomaceous earth at the bottom of window sills and around door jambs will discourage their entry. Crack and crevice sprays — like Don’t Bug Me — will break down quickly in the environment and are also good for this use.
• Because it’s the chosen habitat and breeding ground of the bug, female boxelder trees are sometimes removed to decrease the insect’s number. This seems a rather radical move and is a mostly fruitless one as well, especially in areas where boxelder trees are numerous. The insects’ eggs disperse on seed pods — the “helicopters” produced by boxelder trees — and adults will fly as far as two miles seeking new sources of food and breeding grounds. Tree removal is not recommended, unless yours is the only boxelder tree for miles around and the bugs have been a persistent problem.

Insecticide For Boxelder Bugs

Box elder bugs are a common household pest in many areas of the United States. They are attracted to the sap of box elder trees and will congregate on the leaves and branches of these trees in the summer months. When they enter your home, they can leave behind a sticky residue that can stain your walls and furniture.

Box elder bugs are brown with orange-yellow patterns on their backs. They have long antennae and wings like all true bugs, but they cannot fly very far or very high off the ground. These insects can be distinguished from other similar species by looking at their legs: box elder bugs have five pairs of legs while other species have only four or six pairs.

Box elder bug infestations can be treated with an insecticide containing permethrin or pyrethroid compounds; however, these treatments will not solve your problem entirely because these insects reproduce quickly in warm weather conditions such as those found throughout much of the United States during summer months when most people experience box elder bug infestations at home or work premises where they live and/or work during this time period every year without fail every single year without fail ever since I was born
