DIY Stink Bug Options

If you've opted to do battle with the brown marmorated stink bug on your own, without purchasing traps or chemical pesticides, you can still mount an effective attack.

Sealing & Mechanical Exclusion

The most essential part of dealing with a stink bug infestation is keeping them out of your home. First, make sure obvious points-of-entry are dealt with, including broken or open windows, gaps under doors and open chimneys or fireplaces . Once that's done, move on to the smaller, more concealed entryways. Just about every home will have these, whether they're in roofing, foundation, basements, crawlspaces, siding or elsewhere. The easiest way to fill these cracks is with some self-expanding foam sealant , but if you're opting to fight back without buying stuff, you can whip up a pretty decent seal with the following:

  • flour
  • salt
  • water
  • sawdust (optional)

By mixing about a teaspoon of the flour and salt, a drop or two of water, and a pinch of sawdust, you can create a decent joint compound . Apply this solution to cracks your cracks and sand until smooth.

Unfortunately, the self-expanding stuff is a pretty complex polyurethane-based concoction. I'm not sure there'd be an effective (or safe) way to make this stuff on your own. Unless, maybe if you were a highly trained chemist. And then, why would you be reading this?

(And of course, you might also consider using duct tape.)


Many people are finding success by making their own stink bug traps. There are plenty of homespun designs out there on the internets, but the one that seems most effective is a variation on the old fish trap, where a plastic bottle's top is inverted into the body. Julian Smith of New Jersey designs his stink bug traps using a two-liter soda bottle, and according to his local news station, the results are great. Of course, you still have to discard the deceased bugs, and if you're not careful, that can be a smelly procedure. Here's an incredibly handy video on how to put together your own stink bug trap...

Dealing with Invaders

Before you go firing up your vacuum cleaner, remember, they're called stink bugs for a reason. Still, the best method for catching stray stink bugs is with suction. If you have an old, junker vacuum, opt for that before using your nice new one. Or even better, if you have a shop-vac (wet/dry) , go for that. With many new wet vacs, you can actually put some soapy water (or diatomaceous earth ) in the drum to help kill the bugs.

Homemade Insecticides & Repellants

Liquid dish soap and hot water from a spray bottle works quite well in killing stink bugs. Also, some diluted bleach water works pretty well, but be careful where you spray (it'll irritate skin and potentially discolor clothing and furniture).

Boil down some orange and lemon peels in a reduction to mix with some hot water in a Spray Bottle to create an effective repellant.

Got some chrysanthemumschrysanthemums in your flower bed? Boiling about 100 grams of dried mums into a gallon of water for 15 to 20 minutes, then straining into a Delta Sprayers 82413-32 24oz 3pk Spray Bottles will yield an effective, natural pesticide.

Recruiting Feathered Friends

If you don't have a chicken (or don't feel like owning or buying one), you can, and should, still recruit birds. Many people have reported seeing robins, titmice, and starlings eating the brown marmorated stink bug. It was believed that the odor emitted by stink bugs prevented the bug from having any natural predators, but it would seem some birds have developed a taste. Install a bird feeder , bird houses and spread seed around your property to attract birds and encourage them to stick around.
