These insects are not bad, but they can be a nuisance to us in our homes or offices. We have 3 venomous spiders in Oklahoma; the Black Widow, the Brown Recluse (Fiddle Back), and the Brown Widow.

Black Widow

She likes to make her irregular web in dark undisturbed places. They are normally not in high areas.

She is big, shiny black with a red, sometimes orange, hourglass shaped mark on her belly. She’ll sometimes have a red stripe going from her rear end up her back. She has long spindly legs.

Her eggs are smooth and silky.

If bitten by one, seek medical help immediately. Their bites are seldom fatal.

Brown Recluse (Fiddle Back)

She likes to make her irregular web in dry undisturbed places. They favor wood piles, boxes, and other undisturbed things around your home or office.

They are normally a brown or gray colored spider. The shoulders and the rear end may not match colors.

They have a dark brown line on their shoulders that resembles a violin. They are long spindly legs.

Their bites may cause damage to tissue and medical help should be sought if bitten by one.

Brown Widow

She is not as elusive as the black widow. She likes to hide under ledges, rails, picnic tables, loose tree bark, etc., in well lighted areas.

She is more of a brownish color, but may be darker or lighter based on her surroundings. She has black bands around her knees which are obvious. Where the black widows markings are red or orange, hers are orange.  Caution: This spider may not have these specific markings because they conform to their environment. Their legs may be solid color. Their abdomen may be mixed colors or solid colors. This can be a trick one to identify at a glance. She still has spindly legs.

Her eggs are jagged, not smooth.

While their bite is normally not as severe as the black widow, medical help should still be sought if you get bitten by one.

We do a thorough inspection to find the problem areas, advise the treatment needed and the frequency of treatment, and treat accordingly.

We treat them with a liquid chemical or residual dust. We also take down their web.
