Too many bugs hanging around your house and yard? Here's a DIY guide to the most common ones, with information on what they are and how to get rid of them.
We do-it-yourselfers seem to have more wasp appeal than “normal” folks, what with exterior painting, gutter repair and yard work. Try to get the nest in the spring before it gets big. Keep an eye on the wasps for a while to see where they go—either to a nest or to a hole in the ground. Use an aerosol wasp and hornet killer; it will shoot a stream of non-staining, quick-acting insecticide directly on the nest—up to 30 ft. away. Caution: The stream is powerful—but also toxic.
When box elder bugs swarm in the fall, you may think they're taking over your house—maybe even the world! Even though they're harmless, here's a solution. Look for major congregations of bugs outdoors and spray them with a strong solution of soapy water. Keep the spray bottle handy, and spray wherever they recongregate.
Before you start whacking away at invading ants, figure out where they're coming from. Look for a trail, or a pattern in their appearance. The best way to control them in the house is to kill them in their nest. If you find the nest outdoors, apply an ant insecticide directly to it. If it's inside a wall, drill a 1/8-in. hole and squirt an insecticide or boric acid dust into the cavity. If you can't find the nest, use ant bait. The containers look like tiny flying saucers with holes in the sides. They do work, but you may not think so at first; it can take weeks to kill them all.
Check what your ants are eating. Some brands of bait work for sweet-feeding ants; others (like ant traps) attract protein feeders. If one type of bait doesn't work, try the other, or put out both at the same time.
Don't worry. They're mostly harmless. Carpenter bees are huge—like a bumblebee—and they look ferocious, and they can be very defensive about their territory. But they rarely sting, and even though their tunnel-like nests inside deck wood and under eaves look destructive, the nests are usually small, and control is easy. After dark, squirt an insecticide, labeled for carpenter bees, in the entrance hole and caulk it closed a few days later.
Look, we won't kid you. Yellow jackets, a type of wasp, have the human race beat. Those big hummers that try to take away your hamburger when you eat outside are almost invincible. You can kill their underground nests by pouring lots of soapy water down the hole, if you're lucky enough to find it. And you can eliminate outdoor sources of food and water—uncovered garbage cans, pet dishes, drippy faucets. For above-ground nests, try an aerosol wasp and hornet insecticide.
The first step in controlling them is eliminating all food and water sources.
Running across my kitchen floor! Scientists say that for every cockroach you see, there are 100 to 600 more hiding in cracks and under your dishwasher and refrigerator. Now don't you feel better already?
Getting rid of their food is the first step in getting rid of them. Clean up every speck and crumb—from shelves, drawers, pantry, under appliances, under the sink. Store any accessible food in plastic containers. Equally important: Remove the roaches' water supply. Fix leaky sink traps and drippy faucets. Elevate Rover's water dish. Eliminate damp dish towels, sponges and scrub pads. Sealed bait containers like Roach Motel are most effective. Boric acid pesticide powder also works. Just sprinkle it lightly into all cracks and crevices. It's long-lasting and relatively nontoxic. Look for it at hardware stores and home centers.
We don't recommend spray insecticides; they're quite toxic for use around a kitchen, and not very effective. Many roaches are immune to them.
No, probably not. Meal moths, also known as pantry moths, get into dry food like flour, cornmeal, beans and dried fruit. Also food-based decorations and Christmas ornaments, birdseed and dog food. Either toss out the affected stuff or put it in the freezer for at least four days. Or heat it in a 130-degree oven for 30 minutes. Meal moths don't carry disease, so after picking the dead bodies and larvae out of the food, you can eat it. (Arrgh! Not me!)
Next time, store your food in glass or sturdy plastic containers with sealed lids. And would you believe this? High-IQ meal moth larvae can penetrate unopened plastic-wrapped food and then hatch.
Carpenter ants tunnel through wood, but don't eat it. Reproductive carpenter ants are winged, and when you see them they're leaving the nest.
Termites build mud tubes to get from the ground to the food source in your house.
Flying termites can leave piles of wings behind. Worker termites stay hidden in the safety of tunnels and nests.
You find a swarm of ant-like bugs with wings inside your house or on the siding. You think it could mean trouble, and you may be right. They might be carpenter ants or they might be termites. Both will eat your house. And in both cases, the ones you see are reproductive individuals leaving the nest. You can tell the species apart this way: Carpenter ants have a pronounced “waist” and back wings that are shorter than the front wings (not shown).
You can usually deal with carpenter ants yourself: Find the working ants. They're large and black. Find the nest and use insecticide directly on it, or use bait. Be sure either product is specifically labeled for carpenter ants. Then fix the moisture problem that gave them their cozy habitat; it's the wet wood that attracts them.
But if you do have termites... don't mess with them. Call a state-certified pest management professional—even if you're just guessing that they're termites. A termite inspection will cost a little, but repairing termite damage could cost you thousands. A pest professional's work is usually guaranteed and normally includes a reinspection every year after treatment.
Termite signs: Here's what to look for:
Reduce the risk of termites by eliminating all wood-to-soil contact around the house.
Any outdoor pet can pick up fleas from chipmunks, squirrels or rabbits. But you don't want them on you. Adult fleas may target your pet, but they live in your space too—on the floor, ground or bedding material—wherever your pet hangs out. That's why it's essential to treat those areas as well as the animal.
First, thoroughly vacuum the carpet. Wash bedding in hot water. You might need to steam-clean carpeting. Outdoors you can use insecticide.
Treat your pet with one of the various flea killers available at pet stores, or better, ask your vet about one of the flea killers given orally. These products get into your pet's bloodstream, and when fleas bite, they become infertile. Eventually the whole population dies. Unlike other flea-killer powders, the oral treatments are completely harmless to mammals.
What do you do if you've got a swarm or colony of bugs that you can't identify, and they're a nuisance, or you suspect they may be harmful? Your local county extension service may be able to help. Or try the National Pest Management Association's “discussion forum” at www.pestworld.org. You can also check with a pest management professional.
