House fly eggs resemble small grains of rice. The eggs hatch into larvae, also known as maggots, which range in size from about ¼-3/8” (7-10 mm) long. Maggots are cream colored with a greasy appearance.
Aphids. Aphids are sap-sucking tiny soft body bugs and affect the plant when the plant is under some kind of stress like drought, overcrowding, etc. The eggs of aphids look a lot like sesame seeds. They are encountered in colors like yellow, green, black, red, and even black.
House fly eggs look like small grains of rice. Eggs hatch within 24 hours, and house fly larvae emerge. House fly larvae, or maggots, appear similar to pale worms.
Fruit fly eggs measure only 1/2 mm in length. Under a microscope, they are yellow in color and appear to be the shape of a grain of rice.
Deer tick. Eggs of deer ticks look like sesame seeds, and they can easily spread them all over your property. You need to find and eliminate the eggs as quickly as possible because ticks pose a serious threat to both humans and pets.
In fact, they have a whole bunch of names, some of them misleading: onion seeds, black cumin, charnushka and kalonji, to name a few. Although they resemble onion seeds or black sesame seeds, they are actually the seeds of Nigella sativa, an annual flowering plant of the Ranunculacae family.
Bedbugs: An Overview
If you spot something that looks similar to a sesame seed, but definitely is not, you might be looking at bedbug eggs. Now, if you see something seed-like that is brown in color and is moving, an adult bedbug might be the culprit.
Flies lay eggs in different sizes, shapes and locations, depending on the species. The common house fly lays eggs that resemble grains of white rice. Within 24 hours of being laid, maggots emerge from the eggs. These maggots – or fly larvae – look like tiny, pale white worms.
These segments often are compared to rice, sesame seeds, or small white worms, and they are filled with tapeworm eggs. Tapeworm segments start off white and mushy when they leave the body and become more yellow and hardened as they dry out as time passes.
Thrips. Thrips look like brown seeds, but thrips droppings do look like tiny black bugs that look like poppy seeds. On a plant with thrips, you will notice that as these insects feed, they will leave tiny black droppings on the stem and leaves.
The main goal is to quickly eliminate the breeding site, which means removing the eggs and maggots and then thoroughly cleaning the area. After you eliminate the breeding site, focusing on the adult flies in the area is next. Remember, they breed very fast so it's important to act immediately.
Fruit Fly Eggs: 0.5 mm (0.02 inches) long and can't be seen by the naked eye. They are yellow in color and similar in shape to a grain of rice but much, much smaller. Fruit fly larvae: AKA (maggots) are 3-4mm (0.125 inches) long and is wormlike and pale white/yellow in color.
Fungus gnats
Fungus gnats are annoying little flies that look like poppy seeds when they land. They can sometimes be mistaken for mosquitoes or midges but don't bite. They lay their eggs in damp soil and may appear in your home if you have houseplants.
Tapeworms. This is the intestinal parasite that you are most likely to see with your naked eye. They look like grains of rice in the poop, or when they are dried they look like sesame seeds.
Colour: from white to dark brown depending on the roach species and development stage. Size: < 1 cm. Shape: resembles a flower seed or a bean. Location: ootheca is hard to see, because of its size and location.
The entire tapeworm is quite long, 6 inches or more in length, which most people find surprising as all they usually see are the small egg sac segments which are about the size of a sesame seed or grain of rice. The segments are very flat, like a piece of tape, hence the name of the worm.
Adult bed bugs will look like flax seeds only 3/16-inch long.
Recognising bed bugs and their eggs
They are visible to the naked eye. Adult bed bugs are usually brown in colour. When filled with blood, their colour ranges from red to dark brown. They are oval in shape and about the size of a flattened apple seed, 4 to 7 mm in length.
Egg: The white egg, about 1.2 mm in length, is laid singly but eggs are piled in small groups. Each female fly can lay up to 500 eggs in several batches of 75 to 150 eggs over a three to four day period.
House flies typically lay eggs on animal feces and garbage. White, legless maggots (the larval stage) hatch from the eggs and grow to about ½ inch.
Egg laying begins after the adult female is 10 days old, with maggots hatching within 24- 48hours. Larval development takes approximately 8-10 days, with development from egg to adult taking about 3 weeks.
These small spots are often bed bug eggs. They are oblong with a semi-transparent or white look like a grain of rice. These eggs are very tiny, but you can spot them since their eggs are usually clustered together.
These little black spots are sometimes smeared making them look almost like pencil marks. They are actually bed bug droppings which is pretty gross. Make sure to check your mattress, sheets, bed frame, and box spring for these marks.
The droppings consist of digested blood, so they will no longer be red once they dry. The spots will be darker, rust colored or black, and are about the size of a dot from a marker. If you think you may have a bed bug infestation, check for bed bug droppings around the corners and edges of your bed.
